Henrik Grobelnik ( of ActionSportGames, A/S - http://softgun.dk/ ) very kindly organised for this new CA M15A4 to arrive with me for review and testing. ActionSportGames A/S, Denmark are the exclusive world wide licensee for the ArmaLite trademark and design in relation to Airsoft guns. So firstly a big thanks go out to Henrik for making this review possible!

The Classic Army M15 as we see it now in it's latest incarnation, the M15, is the result of several permutations of this AEG from Yick Fung.

The original CA Colt M4 series hit the shelves around mid-June 2002, at which time we published an honest review of one of the first batch (written by Comega).

I had the chance to use and fire the original version 1 ClassicArmy M4a1, and true it was a heavy full metal item, but as out the box rifles went, truth be told it was not exactly desirable. The gearbox sounded distinctly painful when fired, and running on standard batteries the gearbox had a habit of locking up (it really needed a >=9.6V high mAh to crank it). Numerous problems surfaced over the coming months after it's release, with major issues highlighted such as:

  • the plastic that the stock and foregrip were made from being far too weak, and prone to snapping
  • the barrel tightening ring lubs snap off
  • the foregrip fell off far to easily
  • the gearboxes regularly jammed

Over the coming releases several improvements were made:

  • v2 had general updates to it, these being mainly internal adjustments.
  • v3 had the original Colt markings removed, which were instead replaced with ClassicArmy markings. One can only speculate over the removal of the original trademarks, but it's almost certain that a dispute of some sort took place. The bodies were much more well built in this version. V3 also had one piece receiver tabs, rather then singular ones stuck to the upper receiver that broke off.

So what's new to the v4 ArmaLite series? Well CA teamed up with ArmaLite Inc. in the US, and ActionSportGames A/S in Denmark (http://softgun.dk/).

The main improvements surround the power output, and the external build quality. The plastic parts are made from a much more durable fiber reinforced polymer, that is much less likely to shatter or crack, the bodies have been severely improved, this time featuring original decals, and the gearboxes have been fixed up.

It transpires that a spacer/shim fitted to the spring guide in the pre v4 CA ArmaLite was responsible for the gearbox failures as it placed considerable strain on the gears, and led to catastrophic failure when the slightest problem occurred.

The official list is given as (ref news article):

  • New Metal Body - ‘Armalite’ Real Gun Logo / Laser Script
  • Improved material of Hard Grip, Foregrip and Retractable Stock (Change from Plastic to Nylon & Glass Fiber)
  • Individual Series no. will be added
  • New Gears will be used (high speed gears and motor)
  • Re-enforced Adaptor Ring for Foregrip
  • New Version of Hop-up Chamber & Rubber
  • High Speed & High Torque Motor
  • Takes up to 10.8V in stock

To say that the v4 rifle is an upgrade is really complete rot, the v4 is miles ahead from the previous versions, it's like saying that humans are an 'upgrade' from monkeys, there's really just such a huge gap between them, sure they look similar, but they don't act or perform in the same way. The effort placed into the v4's production positively shines.

The new ArmaLite Airsoft rifles were first shown in the US at the Shot Show in Orlando on 13-16 February 2003. ArmaLite had them on their booth where they drew a lot of good attention and were met with a great success.

I'll try to leave off making direct comparisons between this AEG and the TM M733, as I'm putting that into a separate review.

Please note that in some shots you may see what look like scratches and marks in the receiver if you look closely. These weren't on the M15 when it arrived, but after being dragged around with me for a skirmish, and generally 'used' is aquired a set of scratches on the front ring, receiver and flashhider on the LHS (the side facing me when I hold it). That isn't CA's fault, it's just that I was testing the M15 in the frield for this review.

Out the box Well the word "wow" comes to mind. To put the looks into one simple phrase this is, put simply, the best stock/standard AEG I have ever seen out the box. The realistic markings are amazing, the plastics look great and generally speaking I can't think of anything that either gives it away as an Airsoft piece, or could be improved upon.

The box itself is getting somewhat similar to TM's own, even with a mock TM style 'hopup' logo. Of course there's CA's new logo on the box, and ArmaLite's own logo emblazed on the front. A nicer touch with the new CA boxes is that it has the right picture/label on the top of the box, rather than a generic logo of some sort. Hey it's the small things in life that matter. :)

Grabbing this piece out the box and swinging it around, it just doesn't feel like it was made by the same company as the first CA M4a1 I saw. It just feels stronger, more rigid, and simply put better constructed from better materials.

In the box you'll find the AEG itself, a cleaning rod, sight adjustment tool, and a hicap magazine (and a heap of paperwork).

First looks: Well it's a heavy beast, clocking in at 2.7kg with no battery.mag/ammo in it. You really feel the weight when you pull it out of the box for the first time. The other thing that struck me was the feel and texture of the front and rear grips, there's no rattle to the piece, and it just feels dead solid.

This can really be split into three sections:

Metal parts: Unlike my older CA MP5, there's no horrible pot metal (aka monkey metal) anywhere to be found. The castings on the carry handle aren't exactly wonderful, but I'm sure the real thing isn't too hot in that area either,

Plastic parts: As has been mentioned the new plastics are glass fibre reinforced, and very very nice. The stock doesn't split apart like previous versions that I've seen, and I'm fairly sure I could stand on the grips and not have them crack. Again, I don't know what the real grips are like, but these are a very pleasant texture to hold and feel very strong.

Detailed parts: The sights are very robustly built, with all the correct lettering. The markings are laser engraved in white down the side of the receiver.

Features: The M15 tactical carbine features a one piece metal barrel, all metal parts, a tougher foregrip, engraved receiver, removable carry handle, comes with a hicap magazine in the box, reinforced stock and features better wiring.

The fire select switch is much improved over previous versions, it's a nice tight fit, and clicks into place very nicely. The marker on the other side of the receiver does not turn with the selector (like the real steel does) as there's no way to put a connector through the gearbox at that point.

Unlike the TM Armalite copies, pulling the handle below the carry handle back does not release the dust cover. This is mainly down to the thickness and differing shape of the metal body.

Lets start from the front of the rifle, the flash hider is removable to reveal the usual 14mm threading for accessory fitment.

The barrel has a nice powdercoated look to it, matt and looking very realistic. Orientated on the RHS slightly to the top of my barrel I found the markings "5.56 NATO 1/7" with "C MP" marked above that.

The front sight mount features a side mounted sling loop, which is more useful (at least to me) than the underbarrel mounts. You'll also find the bayonet lugs underneath the sight, which is suitable for mounting items such as bipods. The front sight can be reversed and place on the other side of the barrel if needed, simply push out the securing pins and remove and refit the unit.

Under the front sight you'll find a small allen key threaded bolt, if the front sight becomes loose, that one will need tightening.

The foregrips as I have mentioned are of a texture and build that is very pleasing.. it's difficult to say more. The ring that you must slide back to remove the foregrip halves is more than a little amazing. Unlike some TM models, and the older CA models where the slightest knock or gentle breeze would leave them dropping to the ground, the new CA ring is held on by a spring that need hands of steel to move.

Yes guys, CA took the world rather seriously when we said the foregrip ring spring was a little weak. Unless you have a habit of turning green and bulging when you get angry you may find this ring almost impossible to slide back to remove the grips.

This isn't so much of a problem for people with the tactical carbine version, but anyone looking to hide a battery inside the foregrip (such as on the M4a1 clone) may wish to look into seeking out the real M4/16 foregrip tool, which allows you to easily slide back the ring to remove the grips.

I found that it is possible to push the ring down by hand and remove the grips, but it takes a certain 'nack'. Place the stock on a flat surface at your feet with the barrel pointing vertically upwards, stand over the rifle and then place both hands around the ring. Using your bodyweight carefully press down on the ring and remove the grips. Refitting is simply done in the same way.

The rear sights are fitted into the carry handle. There are two backsight holes available, one larger and one smaller. The larger hole allows more light through, and easier snap shots to be taken, in short the larger hole is more tactical whereas the smaller hole affords a more accurate shot.

For Airsoft usage the larger hole serves me well but you may find your personal preferences differ. A fair amount of light can get around the backsight, personally I prefer blocking the side up with a little black PVC tape to allow easier co-opting aiming.

The carry handle is easily removed - there are two thumb clamps with slots in them. Should they prove to be too tight to remove, simply use a large slotted screwdriver to easily undo and remove them.

The threading is perfectly normal in orientation (counter clockwise to remove, clockwise to tighten), but don't force it the threads aren't as strong on the real thing and you can shred them if you're not careful.

If you have a look into the mag well you'll see the black gearbox chassis the reinforced hop unit, and the metal nozzle. I'm afraid it's difficult to get good shots inside the well as it confuses the auto-focus on my digital camera:

The grip externally looks pretty much like any other M4/16 grip that I've used, although the CA version features a heat sink style grip plate. I've not managed to get the motor so hot that it needed the heatsink myself, but I'm sure on higher voltage batteries and hotter days it may well come into play.

The motor tightening bolt is large and easy enough to get to. There's no need to touch this unless you upgrade things internally (which is unlikely to do), but again, it's nice having an overspec'd adjuster, as the TM allen key bolts are a bit too easy to accidentally undo and loose.

The rear stock features what I am given to believe is a replica of a tool storage cover, but on the AEG version allows you to slide the battery into the stock.

MY 8.4 3000mAh fitted fine (7x C cell), and CA tell me that a 10.8 will fit in there. Heaven knows how fast the thing will turn on a 10.8 though.

To fit the battery, slide the wires out, then slide the battery in bum first, attach the power wires together and tuck the connectors/fuse in after the battery.

You'll also find the rear sling loop mounted underneath the stock. This is somewhat confusing, and may hinder the fitment of some 3 point slings, as the front sling mount is on the side and the rear mount is on the underside of the stock. I prefer side mounted sling points as when the rifle is on your back it allows for it to be more tidily stored away. Again each to their own here.. I just prefer both sling mount to be on the same side as easch other. ^_^

Functionality - so what do all these levers and things do?

Dust cover - The dust cover hides access to the hopup unit adjuster. It's held closed by a magnet, and to flip it down, you just flick it with the corner of a nail. The cover is spring loaded and will stay open until it's moved back into position for the magnet to hold it.

Cocking handle - the cocking handle does move, but it's just for show, pulling the handle back doesn't do anything, but it does make a nice sound when you let go and it springs backl into place.

Bolt release catch(s) - The push button on the RHS, and the lever above the mag release catch don't do anything, and are simply there for show.

Mag catch - the mag catch does of course work, as does the fire select switch and trigger.

Performance So how strong is the M15? Well I've taken the piece out with me, and the AEG had as much of a tough time as I did (believe me it took me 48hrs to recover from the last game). I didn't abuse it, but I gave it a very thorough test, and I can find no problem with it so far.

Now onto this new metal body I mean, how strong is it? Well you can actually clamp the flashhider to a table and suspend the entire body of the rifle (with battery and mag in it) horizontally - as in free floating in mid air. Now that's impressive! If you did that with my stock TM SG1 you'd be a very unhappy bunny with the rather bent and buckled results.

Gearbox innards: I can't really strip the model that I have here for review, as it will invalidate my long term tests of the piece, but I do know what is in them from my discussions with Henrik ( of ActionSportGames A/S - http://softgun.dk/ ), and from information from CA.

The older model that I tried out a year ago sounded terrible when you pulled the trigger. Strangling cats viciously would have been nicer. The reason for this was simple, there was too much strain on the gears and not enough grease. This has completely changed with the new gearbox setup, it sounds wonderful and truly purrs.

The gearbox features highspeed gears and an EG1000 motor, the gearing is basically a copy of the Systema standard ratio flat gear set, and there's also a bore-up cylinder, reinforced spring guide and one of those new yellow pistons in the box too. Lets not forget the reinforced tappet plate, reinforced hopup and metal loading nozzle. It's worth noting that all the gearbox screws have philips heads, which makes any gearbox work a whole lot easier!

Bearing in mind that a few years back I had to pay around £120 for a Systema FTK (and the ensuing exercise to fit the thing), getting an AEG prebuilt to the same spec is somewhat of a luxury.

I also note that the wiring has been improved, and the loom is now made from a much nicer fatter and more flexible wire set. The previous incarnations featured much more brittle wiring, which although got the job done, just seemed "too cheap".

Take down: So how do you field strip this sucker? Well it's not too hard, and the manual, which is all in English (handily, and also shows you CA's target audience), details exactly what you need to know.

Firstly use a good screwdriver.. not a leatherman or multitool. You want a nice flat bladed thin screwdriver that fits the bolts screwed into the receiver pins.

Firstly undo the rear bolt, now with something like a punch (or anything that won't damage the threads) tap out the pin itself.

When you've done this carefully lever the upper receiver away from the lower. Be gentle and apply a steady pressure, and you'll find that the top receiver swings upwards and away, hinged on the front receiver pin. The motion is tight, as the metal receiver tabs slide over the gearbox.

Now two things will most probably drop out of the receiver as you do this. One is the 'orrible shiny cover that the dust cover sticks to to close. The other item is the bolt release button on the LHS next to the "ArmaLite" lettering. So don't do this over grass or you'll be hunting for the parts for weeks.

Because I'm such a nice chap you'll find photos of the two parts so you know where to put them if/when they fall out. ^_^ (ain't my coffee table lovely?)

Take out the front pin (again undo the nut) and you'll now end up something like this (image shown to the left)

The boreup hole is on the RHS of the cylinder so you can't see it in this shot.

The inner barrel can now be removed if you want. Before you pull it out of the outerbarrel make a note of the way up it goes. I was stupid enough to slide the inner barrel back into place upside down with the hopup the wrong way around.

Retracting the inner is easy, but again it's a tight fit, so don't force it. The hop unit is reinforced plastic, so don't break it. Carefully pull the unit backwards from the muzzle end and slide the inner barrel out along the receiver. It will fit between the receiver tabs, but it's tight.

With the barrel out you'll see that it goes right to the end of the barrel and stops just before the flashhider.

Here's a shot of the hopup unit, watch that little spring, there's not much holding it in place so make sure it's in right when you stick the inner barrel back in place.

As you can see this hopup is a straight copy of the TM version, so sourcing spare parts (if needed) won't be difficult.

When you push the inner barrel back into place, again be careful, it's not easy to slide into place back again, so don't force that hopup unit.

When you refit the receiver pins make sure that they are nice and tight.. you don't want to loose one when you're out and about.

Mags: Okay, well here's a selection of mags from the cupboard. From the left we have the following magazines: G&P midcap, TM lowcap, CA HIcap, TM Hicap

As you can see there's quite a variation here in colour. I took the shots in natural light to get them as close to how you see them as possible.

All the mags have lettering stamped into the base of them, the GP mag says "Adventuer MFG.Co.INC. Parsons KS USA". The TM hi/low caps say the same, but in lower case lettering. The CA mag says " Yick Fung Ind. Int'l Ltd. Classic Army". It's also worth noting that the new Thermold mags do not fit into the CA receiver, they seem to be around 1/2mm too wide.

I had no feed problems using either the CA or TM hi-cap mags (actually all of the ones shown here worked fine), so given the price difference I'd recommend buying real CA mags for your CA ArmaLite.

Manual: Here it is scanned in all it's glory. Click on a thumbnail for a larger image (pages are in order).


Niggles: So what is there to complain about? Truth be told.. not a great deal

  • Dust cover magnetic catch - I know it's a very cosmetic thing, but the dustcover is only held closed with a small magnet, and the metal cover inside the chassis that is meant to look like the real bolt is awfully shiny and unrealistic. The shiny ring around the end of the barrel near the flashhider may not be to everyone's tastes either.
  • No foregrip removal tool - CA should give a foregrip removal tool out with the M4 series, as to be honest it's really needed, especially for quick battery changes.

Conclusion: Well the CA ArmaLites had a really bad rep a year ago, and this new rifle is just a whole new beast. There's nothing really wrong with it, apart from a few minor niggles. Not only does it perform well out the box, but it represents huge value for money. The decals are nicely printed, and for our US brethren as the logos are 'approved'/licensed there should be no problem importing these pieces with the logos intact.

Upgrade Potential

8/10 internally it's all nicely copied and the same dimensions as TM gear. Externally you'll find that grips and cosmetic addons may not fit so easily because of minor sizing differences.

Build Quality

10/10 it's built like a rock

Value for Money

10/10 It's just impossible to fault

Overall Potential

10/10 I'm an official CA ArmaLite convert now

In short... I don't think I really want to go out onto the field with a different rifle ever again. The only minor niggle is that as the rifle is pre-upgraded to 1J, it isn't quite as user-friendly to use it for CQB/indoor use against living targets.
