Nooooo! Just about to post this! I'm buying one. Sadly, no fake piston.

nice

How hard would it be to weld a piston on there?

Doesn't the GHK only recoil about half that distance?

Yeah but it's got a small plastic stop in it that really helps to cushion the moving parts. Mine is realllyy reliable, love that gun to death. I wouldnt buy a clone tho, I've seen how AGM M4's are and theyre total sh!t, tho I guess the WA's are too. GBBR's just really need TLC unless theyre a quality build, and so far the GHK has been great.

Only concern is the hopup which is plastic and the bolt head, tho both of which seem to be made out of good quality ABS.

My GHK has about 2 inches to spare, but that has been taken by a big piece of rubber.

Mines like a semi hard plastic. Is yours squishy?

Kinda sorta, I guess semi-hard plastic would more accurately describe it. It's hard, but has some give.

Can't wait to hear if this is junk or not. I've always wanted a GBBR, so a drop kit this cheap would be amazing if it's of good quality.

hmm, so with the purchase of a Dboys/Kalash AK for ~$150, thats a DIY GHK Kit for ~$300. not bad, and definitely tempting, but I think I'll wait for WE's solution, given their recent pricing scheme

Oh, for gods sake....

WHY DO I OWN A 47??? ;_;

Hmmmm extra mags are how much, bb capacity?

GHK mags are about £35 in the UK at the moment, so I'd expect the clone ones to be on par with a chineese hicap; IE, £15-£20 when shipped to the UK, dirt cheap when in china.

Though, there's only so far you can drive the price down on something complex like a Gas mag.

Given that a GHK needs most of the major internal components replacing with RA-Tech parts, I'm exceptionally wary about this as a 'cheap' alternative.

Expect to budget another £100 or so on replacing the externals with quality reinforced components - presuming it's even compatible (can't view from work so I can't comment).

thing is you're not having to spend 250 bucks on a GHK kit (thats a bugger to find now in kit form anyway) in order to throw 90 percent of it away

now you get to spend 140 bucks or so, and if the fire control parts are steel then you actually have a fair few less bits to throw away

buy a new DG or RAT bolt carrier, and a new RAT npas bolt

you might even be able to buy an RAT or DG hop chamber as it looks like this kit is using the old style hop, so the bits you need to scrounge from supplied hop to complete those will have a good chance of fitting..

I hope the reviews are good. It's almost too good to be true. I wonder when the DBOYs GBB kit will come out, it has the gas piston.

not sure if the dboys has the gas piston or not Only photo of it thus far was an external shot where cant actually tell one way or the other..

Also bear in mind the gas piston will also require a slightly different bolt carrier from standard GHK ones - if dboys bolt carrier is pot metal or cast steel and you want a decent CNC'd one to replace it, then Im not sure if the RAT steel carrier is available to buy in 'can attach gas piston' version as a standalone part?

This is pretty interesting as it says steel made I'm going to presume that its all steel, in which case theres a good chance that you can save most of the parts. Will be interesting to see some reviews of this.

I'm talking about this thing:

From this thread:

They didn't say who makes this one. I thought it was DBOYs, guess not. Supposedly it's cheap, $120-ish.

Snorkal man, any parts you recommend replaceing besides the bolt? Can these take AEG barrels? Forgive my ignorance...

I was about to buy one of these last night until we realised they are not in stock yet

I've seen many of the parts break over on the threads on www.gasguns.info. I would replace the hammer, valve knocker, and there is another piece that prevents the gun from firing without the bolt in it, can't remember what it's called. Not to mention the springs break, but can be replaced with ones made of piano wire.

I ended up getting the whole daytonagun kit ($300), hopefully it all holds together, I'm still not so sure about a plastic hop-up and steel/aluminum bolt group.

The missus just ordered one for my birthday so I guess that's me doing a review

reason those break is they're usually made of some of the cheapest naffest pot metal known to man and quite inconsistently too (so you end up with ###### grain structure air pockets etc on some of them and those give out in no time)

If the hammer etc on this one are steel (even roughly cast) then those should hold up OK as they arent under a lot of stress - just more than the roughest of the original pot metal ones could handle

main two parts Id wait n see on are the bolt and the bolt carrier theres soooo little metal supporting the screws that limit the bolts travel within the carrier that a carrier ran off from anything short of cnc'd billet is just asking for probs - and this one has a bolt carrier that looks like its been pretty roughly cast.

Time will tell wether it holds up or not (ie I wouldnt run out and buy one at same time as the kit but Id certainly budget for the need to go out and buy a decent carrier in worst case scenario)

Main issue with the original style plastic hop unit is actually the tab underneath next to the BB feed that trips the BB release on the mags rather than contact with the nozzle. Cause of the angle the mags get inserted at and way it was originally designed its a wee bit more prone to snapping the tab than it could be, and a snapped one would prevent the mag from releasing BBs into the feed.

Looks promising and let us know how easy it is to install, 1st Commando. It's a shame there isn't any AKM/AK47 mags out there. I'm debating a DaytonaGun drop in kit, if I can find one or this.

-Piano.

I waiting for dboy or cyma.

Has anybody else recieved one of these yet ?

Just got mine through the post but NO instructions which could prove interesting.

I'm off to have a look through the review section to try and glean an idea from the GHK reviews

Keep us updated mate. I'm hoping for the best.

I've been hearing rumblings about this for a while. People out here in Hong Kong right now are VERY excited about it even though no one's had direct exposure to it yet. GBBs in general appear to be just as popular out here with the HK crowd as it is with the international crowd it seems.

What're your overall thoughts with the build quality? Can you post some pics of it? I'm was interested in getting one of these to do a GBBR AKM, but I've been waiting to see some hands-on reviews first.

RA-Tech had instructions on how to install the GHK GBB kit on their website. But I can't find it. It shouldn't be too hard to figure it out. I'll see what I can find as I want to see it working as well.

does this help? or you saw it already

Mine is now built despite needing a little modification to ensure reliable semi (will explain later)

The only problem I have now is the gun seems to give poor blowback unless held with the muzzle in the air .

Does anyone have close up pics of the GHK bolt carrier group as I suspect there maybe a small spring missing from my recoil unit ?

I'll update properly after supper but I can confirm build quality is surprisingly good !

quick update and first impressions.

The kit arrived very well packaged in polystyrene inlay inside of a card box.

Each of the main components have individual compartments while the springs, screws and small parts are all bagged in clear seal bags.

Using the RaTech guide as a rough reference made installation quite easy save for the hole for the selector paddle which on my AKSU was not filled with a pin and needed to be drilled out !

The hop was very easy to install and appear to adjust well.

The semi auto spring which sits on top of the trigger and under the sear was too weak so I inserted a short screw underneath it to give it a bit more tension and now it shoots semi fine !

The bolt carrier is a good solid lump although like all the other parts was coated in a horrid chinese grease.

Mine still only gives full performance when pointed muzzle up so any ideas on how to rectify this would be great.

I will take some pics tomorrow as for now I have stopped fiddling

Uncompany now has a "UN Special AKS-74U GBB Rifle" for 151$. I think this might be the BF kit thrown in a Cyma or Kalash AKSU. Does anyone know for sure?

when I fitted GHK kit my kalash had a pin but it would be hard to notice it (all you could see on inside of the receiver was a very faint circular line on the strengthening plates) - unlike the other pins you can knock out as soon as lookign at them, that one was in as tight as gnatts chuff and needed a 4lb hammer and a fair bit cursing to knock it out (the side mount plate for the sight didnt help either as it got in the way of knocking it thru)

far as the optimal performance pointing straight up goes Ive never came across that one - give the tabs at rear of the boltcarrier/channels it runs on in the receiver a good look over Same goes for the channels on the carrier the bolt and nozzle assembly rides along. Theres usually a fair bit of play in those on the GHK kit so just wonderign if you have a slight alingment issue thats letting one of those assemblies drop a little too low and as a result is driving the parts slightly 'into' their channels rather than just 'along' them when gun is held in normal position. That might account for why the same parts then ride along the channels as intended when held vertically?

I may try pinching the top of the lower reciever together a little as I suspect that may be the cause as you suggested , thanks for the help Snorkleman

Luckily I removed my sight rail a long time ago so that was not an issue but i'm glad I drilled out the pin instead of spending hours trying to bash it out as that was getting tedious

whats the ratio of steel content on these, if any at all?
how are the mags seals?

I'll test steel content tomorrow when I upload pics.

The mag seals seem fine so far

I'm trying to figure out why all the complaints about this new GHK(cloned) AK GBB kit?

It says "steel made"...ya don't have to be a rocket scientist to know that no matter the grade, it's still likely to be stronger than zinc alloy parts...that's a huge plus

All 1st Commando has to do to test steel (iron) content is slap a magnet on them..if it sticks, well..you get the idea

I'm ordering my kit as we speak...if it is steel, it will make a nice engine for my Ino AK74M or Guarder AKS74U

(not to mention keeping my other 5x GHK AKs company)

the magnet test shows ALL components are steel with plastic nozzle !

You get the blowback fixed yet Commando? Are you sure all the springs are tensioned right?

schweeet!

I placed my order for the BF kit hours ago. Hopefully I'll get mine next week!

I just heard about the Boyi cloned GHK AK ( complete gun)...wondering if they are tied to the new Boyi release

did a quick test this morning and it seems fine.

I suspect it like to have a little warm up time after you fill the mag with gas or else it suffers cooldown

Video and pics please! XD How strong is the blowback?

not as strong as my WE M4 but stronger than Guarder aeg blowback kit in my AKM

Thanks for answering my questions mate.

How reliable is it? You can get a shot off with each trigger pull and empty a whole mag on a full charge right? Any parts that look weak or are prone to breakage? Is there a threaded hole in front of the bolt for a piston?

being a bit cool i've not tested it fully on auto yet but short bursts are fine and fires every trigger pull if you don't let a BB drop under the trigger when stripping it
It certainly looks and feels very tough !
I'll check the front of the bolt shortly

huh? what threaded hole are you referring to? Threaded hole in front of the bolt for a piston? The piston lies in the rear of the bolt/nozzle

are you familiar with the GHK bolt design?

are you referring to the current(and clone) GHK design on the bolt carrier? There are two brass screws that prevent the bolt/nozzle from coming off...here's a pic of a bolt I machined for one of my GHKs. The bolt is in its forward-most-position in the bolt carrier:



otherwise, the bolt(not bolt carrier) is made up of 6 parts:
-piston body (piston head is integrated)
-nozzle (and gas valve exit)
-O-ring
-ball bearing (acts as a valve)
-spring for ball bearing
-pin to hold the nozzle to the piston body

There are and should be NO threading on the bolt...on the bolt carrier, YES...there should be two threaded holes for two brass bolt-retaining screws

The only other thread I can think the bolt COULD have is if BF possibly copied RATech's NPAS bolt. ..but the threading would be internal (inside the bolt/nozzle)
