So as you might've guessed, I have an ASR. I stopped using it because it got to the point where it was so inconsistent that I couldn't hit the same 1 foot square twice from 50 feet away. I have the echo 1 upgrade kit and was pretty satisfied with the fps it had. Anyway the problem turned out to be a broken hop arm (plastic, go figure). This part
http://www.airsoftgi.com/product_info.p ... s_id=14769 looks exactly like it. I'm planning on doing a flat hop and I should probably get a new barrel (the madbull I already have is made for an aeg and won't fit the stock chamber) but I wanna know if I should get this part and a barrel that fits the stock chamber, or should I get the pdi type 96 chamber and use my madbull (black python ver 2 6.03mm and 509mm length).
