Hypokondrikern Posted August 7, 2022 Posted August 7, 2022 Hi there, After years with GBBRs I have decided to build myself a lightweight AEG. The base is a G2 gearbox from a used G&G SR15, which will get new polymer receiver, buffer tube, carbon fibre barrel and handguard. This is where I find myself stuck on the build. I haven't found enough info that can steer me into a choice of barrel length nor cylinder. Well, neither spring strength as that is a part of the mix. I would like to have a replica that is built around the 0.28 bb. What is your experience - what would be the ideal barrel length / diameter and cylinder + spring strength to proppel the 0.28? (350 FPS full auto or just under 420 FPS Semi doesn't really matter) Also, How compatible is the G2 gearbox with older G&G polymer / nylon receivers? Or even Cyma receivers? Thanks in advance!
xaphor Posted August 7, 2022 Posted August 7, 2022 I'm in the middle of doing this exact thing, I've picked up an SRC polymer body, I'm going for CF Stock and outer barrel, I'm in the middle of piecing it together but the predicted weight I'm going for is just over 1kg. V2 gearbox's are extremely universal, I'm putting a Cyma one in my SRC body Hypokondrikern 1
Hypokondrikern Posted August 7, 2022 Author Posted August 7, 2022 @xaphor Incredible! Please post some pics when the build is finished. Mine is set to be just under 2 kg. But I find it hard to lose grams beyond that. Will it be a CQB, Recce or normal assault? And do you also have any advice regarding barrel / cylinder optimisation for 0.28s?
Supporters Samurai Posted August 27, 2022 Supporters Posted August 27, 2022 For extreme lightweight you might try this: https://www.printables.com/model/164853-mosquito-airsoft-kit-open-beta?fbclid=IwAR21DHG2pd7Kju6MgZVn7h4Kkvx4XfUIRZzD0Q9G0cs0X9ANVLV_JZd9CWc V3 gb and AK hop. Mags are mp5 mags though. For super-extreme, you can even try it with a plastic gearbox.
Sneaky Posted August 31, 2022 Posted August 31, 2022 (edited) Builds should always meet the requirements of .20g bb at your site. Once passed, you can use what ever bb, just make the finer hop adjustments. Edited August 31, 2022 by Sneaky
