Aod Posted December 15, 2012 Report Share Posted December 15, 2012 mags seam OK. they like to belch liquid gas because of the fast ROF on FA, but i use mostly semi. the construction of the mags is OK, not as solid as a WA/WE/KWA/KJW style mag, but looks like it will hold up. it appears to be made with the same magazine shell as G&Gs regular high caps, so its a rather thin sheet metal. on design, its really easy to load, easier than even an AEG mag. just bung the speed loader up to it and it just fills right up. only downside is if you insert the mag at the wrong angle, you can dump some gas accidentally as the valve protrudes from the mag a lot. but that's a training issue, it wouldn't be too hard to avoid doing so. PS, im still trying to sell mine. trying to get myself away from GIM GBBs. any good offer will take it. The Mags are actually made with a much lower grade of steel than G&G's regular HiCaps which are much more sturdy. The Mags are currently made for G&G under contract by GHK, but G&G tell us that they'll be making them themselves soon. If you're having gas-venting issues on Full-Auto, it's entirely possible that your Upper-Gas-Assembly needs regreasing, I've found that a correctly greased one of these is fine for bursts of Full-Auto of up to ten rounds without issue.

I know valve knockers in the forward position can cause issues. Quote Link to post Share on other sites
Horsem4n Posted December 16, 2012 Report Share Posted December 16, 2012 yeah, it hits the lower receiver somewhere. i think the magazine catch or the baxk of the mag well. Quote Link to post Share on other sites
Cannonfodder80 Posted December 31, 2012 Report Share Posted December 31, 2012 I picked up one of these from PAS last month and I'm happy with it. Re the maintenance, they do require oiling but it is a quick easy job (10 minutes). I have also had a few issues with mags not feeding but as I understand it they do need breaking in, also it's worth noting that you should not use the little tab ontop to empty them as it can come off leaving you with a £35 paperweight. Lastly I was told by the guys at PAS that you can reduce the fps by clipping a couple of coils from the recoil spring Anyway, here's a quick pic of mine after I gave it a new paint job with Halfords camouflage paint Quote Link to post Share on other sites
ncvikingx97 Posted December 31, 2012 Report Share Posted December 31, 2012 So you guys are liking these? Want something a little different, but don't want to invest in the heap of money it costs to get some conventional gbbrs running good. This takes regular aeg parts? Has anybody tried to change the body on the gun, or actually put the box into a different gun? I heard that g&g is going to release the boxes separately so that current combat machine owners can put these into their guns. Might be worth trying, could be interesting if the boxes are cheap Quote Link to post Share on other sites
John_234 Posted January 1, 2013 Report Share Posted January 1, 2013 Yeah, from my understanding they're just G&G's version of a drop-in GBBR gearbox that RA-Tech or someone else tried to develop. I think they cost $80-ish. Personally though, since box + magazine would make it about 130 anyway, I'd just get a complete gun and build it as a dedicated GBBR. The way I think of it, is the gas efficiency and fun of a gas SMG with the ergonomics of a rifle. They're quite nice for that purpose and priced right. Quote Link to post Share on other sites
ncvikingx97 Posted January 1, 2013 Report Share Posted January 1, 2013 Cool. Might order one tonight if time persists, need to get that coupon. If I order tonight , it will come at 120 with free shipping:p. Might be nice to try something new , also like the price. Wouldn't buy one if i had to pay the conventional costs of a regular one. Really liking what I am seeing, might even try putting the box into my king arms m4:). If that works, ill have a metal gbbr with awesome externals and AEG compatible parts, and a shell for a dmr or cqb gun. Happy new years! Quote Link to post Share on other sites

I'm not sure if they fit into all receivers - I'd see online if people have tried similar. Hope it goes well, and same to you. Quote Link to post Share on other sites
Cannonfodder80 Posted January 1, 2013 Report Share Posted January 1, 2013 Want something a little different, but don't want to invest in the heap of money it costs to get some conventional gbbrs running good. That was what I thought too and as they were on offer at only £100 when I got mine I thought that even if it did turn out to be a sack of *suitcase* I could either just drop in a V2 gearbox or sell most of the body for parts Also I forgot to put in my earlier post that despite the body being plastic and very light they still feel solid as a rock and with the heavier mag very well balanced Quote Link to post Share on other sites
John_234 Posted January 1, 2013 Report Share Posted January 1, 2013 Yeah, though the price can be deceptive. Mags are just as expensive as most of the other GBBR designs, so your cost goes up as your scale up your loadout. Quote Link to post Share on other sites
gisburn20 Posted January 19, 2013 Report Share Posted January 19, 2013 Hi Cannonfodder, How is this working out for you? accurate ? good range? I had a look on PAS website and found these were listed in the clearance section! I had been looking at picking up some G&P GBB PMAGs for my ACM GBB M4 (to finally use it to skirmish with!) but this looks a better bet all round for less money.

LboroSlider Posted June 30, 2013 Report Share Posted June 30, 2013 Has anyone managed to reduce the FPS on this rifle? I saw a review online and he stated that on hot days, this rifle also ran hot, over 370fps. This would be too hot for some sites, but he said he didn't know of anyway to reduce the FPS. Someone talked about snipping a few coils off the spring, but then the FPS would be low in the cold, you can't win. Is there a way to actively change the FPS? Quote Link to post Share on other sites
Horsem4n Posted June 30, 2013 Report Share Posted June 30, 2013 i have tried a lot of things to lower the FPS. the only way to be sure to do it is to install a more restrictive or less restrictive floating valve. i haven't seen any type of NPAS valve for it, so i wouldn't count on one to show up. only other thing i can think of is to mix gases or just use duster on hot days.

Inq Eisenhorn Posted July 5, 2013 Report Share Posted July 5, 2013 Surely you could do a quick spring change on this, wouldn't that drop the fps. I mean, rather than cutting springs, just buy a spare softer(?) Spring. Quote Link to post Share on other sites
LboroSlider Posted July 5, 2013 Report Share Posted July 5, 2013 Thats a good point. Does anyone know if the spring is accessible enough to hot swap it during a skirmish day as the temp changes. (Obviously not mid-game) Quote Link to post Share on other sites
Inq Eisenhorn Posted July 6, 2013 Report Share Posted July 6, 2013 Maybe I'm confused, thinking about it, a spring would only affect rate of fire (?) as it's function is to return the bolt to closed. The volume and expansion of the gas is what gives the bb velocity.....am I right? Quote Link to post Share on other sites
LboroSlider Posted July 6, 2013 Report Share Posted July 6, 2013 Some one did say that you can reduce the FPS by cutting a few coils off the spring, so if this is correct the your theory is sound. I'd much prefer your method than cutting springs and forever reducing the fps in cold weather. Quote Link to post Share on other sites
Cannonfodder80 Posted July 8, 2013 Report Share Posted July 8, 2013 Some one did say that you can reduce the FPS by cutting a few coils off the spring, so if this is correct the your theory is sound.

Skintband Posted July 20, 2013 Report Share Posted July 20, 2013 Yes it is possible to lower the fps of the G&G GBB rifles, and cutting the spring is not the answer. I will have some downgrade parts available soon just hang in there. Quote Link to post Share on other sites
