safx i agree about the upper, but that was due to over torque delta rings. Iv seen RS uppers snap also, not pretty. Oh and i was the one that had to upgrade a lot of PTWs and that over torque delta ring was giving me nightmares (i was scared of breaking them!). At the end i never broke one or crack anything. Patience + proper tools = win.
I love GBBR, i own one + a LOT of parts, i'm trying everything out to see if they are worth it. But heck just the feeling of shooting one puts AEG/PTW's to shame!
