Panoptes Posted April 16, 2009 Report Share Posted April 16, 2009 What parts/mods do I need to make an HK G3KA4? Is it even worth considering? Link to post Share on other sites
ED-SKaR Posted April 17, 2009 Report Share Posted April 17, 2009 G3a4 and a shorter front end? Is there any more to it than that? Link to post Share on other sites
Cannonfodder80 Posted April 17, 2009 Report Share Posted April 17, 2009 I was looking at doing the same with my JG G3 and IIRC the inner barrel also needs to be cut down or replaced as it will stick out of the end of the flash hider with the shorter front end. Hope this helps Link to post Share on other sites
Mat Posted April 17, 2009 Report Share Posted April 17, 2009 Actually scrub what I said http://www.airsoftretreat.com/forums/index...52605.msg568281 The wonders of google. I still don't think it's worth it though, the difference between a G3A4 and a G3KA4 being just 5 inches. Link to post Share on other sites
navymp28 Posted April 17, 2009 Report Share Posted April 17, 2009 G3KA4 for Airsoft is intresting and unique. There are not alot of proper G3KA4's put there. What you will need is the following: HK33 Forearm and cocking tube. MC51 frontsight post and flash hider G3 slither stock And to get super detailed and real a G3 one peice navy style poly lower, similiar to an MP5 lower and the same one that the G&G FS51 has. I have an almost 100% accurate G3KA4 just need the G&G lower for mine. But IMO it is not 100% necessary but the HK33 front is. I used a BE HK33 front for mine, AFAIK the KSC HK33 and associated clones will NOT work for this. I have heard of people putting MP5 lowers onto a G3 but I would just wait for WGC shop to get the G&G lowers in stock. If you were to just start from scratch for a build I would buy an FS51 and add the HK33 front set to it. This would save the majority of the work. All you would need it to source a Frontset.

Panoptes Posted April 17, 2009 Author Report Share Posted April 17, 2009 Thanks. Engineering (and an abundance of time) isn't my forté so I'll probably look to commisioning someone to do this (or pay a fortune for one good to go! ). Thanks for the info, that's just what I was after. Link to post Share on other sites
Mat Posted April 17, 2009 Report Share Posted April 17, 2009 Panoptes, there's the lower receiver: http://www.fire-support.co.uk/store/comers...?idProduct=2345 Link to post Share on other sites
Panoptes Posted April 17, 2009 Author Report Share Posted April 17, 2009 OOS as per usual, heheh! Thanks though, I'll keep an eye out. Link to post Share on other sites
Panoptes Posted April 17, 2009 Author Report Share Posted April 17, 2009 HK33 Forearm and cocking tube. Isn't that too long? Also, what's an FS51? I've seen an MC51... Link to post Share on other sites
Kingmob3 Posted April 17, 2009 Report Share Posted April 17, 2009 G&G's version of the MC51 KM Link to post Share on other sites
navymp28 Posted April 17, 2009 Report Share Posted April 17, 2009 Isn't that too long? Also, what's an FS51? I've seen an MC51... Panoptes- No the HK33 forearm is the actual forearm that was used on the real H&K G3K. And to be honest man this is not a hard gun to put together. I know jack about this stuff and I was able to do it..the G3 series are really simple to tak apart. To swap the Forearm all you really need to do is unscrew the forearm from the G3 and then swap them. I will warn you this though, a battery is not easy. I can't remember if it was a stick battry or a custom nun-chuck I had to put in mine. This is the G3K I built: Link to post Share on other sites
Panoptes Posted April 17, 2009 Author Report Share Posted April 17, 2009 Thanks. Could I (should I) put CA MP5 internals in?... Link to post Share on other sites
navymp28 Posted April 17, 2009 Report Share Posted April 17, 2009 No, different gearbox set up internally. The feed port would not synch up with the body and mags. Link to post Share on other sites
Panoptes Posted April 17, 2009 Author Report Share Posted April 17, 2009 Thanks. Just reviewed the earlier post again: HK33 Forearm and cocking tube. MC51 frontsight post and flash hider G3 slither stock And to get super detailed and real a G3 one peice navy style poly lower, similiar to an MP5 lower and the same one that the G&G FS51 has. What about the receiver? Link to post Share on other sites
Adiventure Posted April 18, 2009 Report Share Posted April 18, 2009 If you were to just start from scratch for a build I would buy an FS51 and add the HK33 front set to it. This would save the majority of the work. All you would need it to source a Frontset. Now will the KSC or JLS work front set work on the FS51? Sorry if I misunderstood, afraid I'm not so well versed in G3 variants. Link to post Share on other sites
Panoptes Posted April 18, 2009 Author Report Share Posted April 18, 2009 That's the problem. It's all very well knowing what parts but will they fit between different manufacturers? Link to post Share on other sites
PlasticMag Posted April 18, 2009 Report Share Posted April 18, 2009 AFAIK the KSC HK33 and associated clones will NOT work for this. Panoptes - it's a G3 receiver. Link to post Share on other sites
Panoptes Posted April 18, 2009 Author Report Share Posted April 18, 2009 Thanks all so far. Slowly getting my head around it! What's the fit of the HK33 front set like? In the comparison here, it looks to me like it won't quite fit to the front of the magwell...? Does the HK33 handguard overlap the magwell slightly? Also, can I assume that the attachment of the HK33 frontset and cocking tube to the FS51 is going to be a weak point? Link to post Share on other sites
T8TRG8TR Posted April 18, 2009 Report Share Posted April 18, 2009 No, different gearbox set up internally. The feed port would not synch up with the body and mags. Okay this is completely random but your sig made my day... and I dont think its worth the trouble to make the G3KA4... Link to post Share on other sites
Panoptes Posted April 18, 2009 Author Report Share Posted April 18, 2009 it's part of a 'UKSF setup' so it's absolutely worth it. Link to post Share on other sites
navymp28 Posted April 18, 2009 Report Share Posted April 18, 2009 It overlaps slightly, it would fit great on there provided the FS51 comes apart like the CA's and TM's. Yeah a BE on would suck because it is plastic. But a CA one would be money. Ohh...and if you want an intresitng look for your G3K there is this: Apparently this is what the SAS have there G3K's configured like. I was reading an article about SRR and they mentioned SAS G3K's specifically and that they had PSG-1 butt stocks on them. Link to post Share on other sites
Panoptes Posted April 18, 2009 Author Report Share Posted April 18, 2009 ---- Anyway - I never realised CA did an MC51. Must check. Link to post Share on other sites
scratch Posted April 18, 2009 Report Share Posted April 18, 2009 They do, SAR Offizier M41 I believe they call it - but the G&G would be better because it comes with the correct lower receiver. But I believe the chap above meant that the BE HK33 has a plastic cocking tube, while the CA33's is metal. Link to post Share on other sites
navymp28 Posted April 19, 2009 Report Share Posted April 19, 2009 yeah I was reffering to the BE plastic CA metal as far as the front sets from the 33's are concerned. Link to post Share on other sites
Panoptes Posted April 26, 2009 Author Report Share Posted April 26, 2009 They do, SAR Offizier M41 I believe they call it - but the G&G would be better because it comes with the correct lower receiver. But I believe the chap above meant that the BE HK33 has a plastic cocking tube, while the CA33's is metal. I note there's a CA33 KA3 and a CA33E. Any idea which? I trust the CA G3 sliding stock will fit the G&G? Will I need to shorten the inner barrel or buy a longer one? If the latter, which size? Link to post Share on other sites
