ProWin sealed hopup
 

i just recieved my ProWin hopup chamber for the AK and i LOVE IT. I havent gotten around to checking the FPS gain (if any) but when that sucker is shooting full auto it has gaind about 20ft of range and the shot to shot consistency is greatly improved.

Doing the install was incredibly easy and i am not a smith by any sense of the word. The only thing i found was that the cocking leaver no longer has a smooth slide and seems to get tight at the end of the slide. My roomate (who is a gunsmith) recons its the because of the increased amount of materieal that it involved with the unit.

I hope this info helps those AK users out there.

sweet I'm going to get me one of those when my current hop up rubber dies and I can have an excuse to replace the whole assembly
