Hi!
I'm making GBB to HPA 350 bbs mags for WE GBBR :
Scar/MSK /HK416 /M4/M16/L85

It's really awesome solution for GBB guns: You have cool recoil, stabile fps, and a LOT of bbs:-) I think hi caps like this one are future of HPA. I hate using standard low cap greengas mags, becouse they works like lates shit with GBB airsoft guns.
If You interesting in having HPA hi cup for Your GBB riffle, let me know: aceton@wp.pl, or check out my FB profile: https://www.facebook.com/Camo-Airsoft... You don't have to do anything with You gun, just plug HPA hi cup and have fun:-) Thats Scar is load with 100 psi and run round 350 fps on 0.2 BBS, perfect for CQB.

Best Marcin
