We have drop this magazine from 1.8m onto the hard floor and continue charge top gas to shoot for so many rounds, no gas leaking sign appeared!
The "open-bolt" system is a better verison of the S.C.A.R GBBR system. No gun jamming at all for so many times and so many friends try out! We all perfer to use the good old unrealistic looking "copper tube" system. W.E should sell this system seperate.
Some internal trigger chassis parts are enhanced, a rubber bolt stop buffer pad is good design.
The polymer body is strong and rigid enough compared with "MaLoYah" AEG plastic body! The colour matching of parts is good as well.
The factory power can not punch through softdrink can bottom. Which we happily to use this G39c as a GBBP pistol shooting indoor rather than outdoor GBBR rifles games!
My first modification is to replace 3 REAL pivot pins (we suggest at least to replace the rear pin), strip out the sticker and replaced the new sticker brought from 3army for HK$20.00, unscrewed the side rails.
There are not much things will be done for this G39c, the German ergonomic design makes this rifle very good handling and no need scope lazer, maybe a touch and sling is enough.
We like this G39c as a GBB! Therefore, any other real stuffs, parts, accessories are not necessary (save money $$$$$ vs M4)!
The gun is boring sofar! It's cheap! Magazine construction is good and resonable cheap 10 mags only HK$2,500.00! No jamming! Just a GBB.......
Will any C-hing lazer print good quality magazine ammo photos stickers for the plastic mags internal! Make the mags look a bit "REAL" hahaha......just saw this printing in a kongwahstreet store!
