I recently purchased an older blackmagic w/ e1 1.06 trigger and grip frame. Got it put ir to it and immediately leaks from the reg. and leak from the front block ok easy fix, now noticed that the asa with is on/off twist you understand, omg will not turn off jammed tight, I had to use a pair of channel-locks to turn it off jesus it was hard, noticed that when i grease the threads the pin looked bent on the on/off knob when turning it, found it was stripped when disassembling it. another thing is that when fired i chopped the first 3 balls then no firing at all. I cleaned it bore and bold clean and so is the valve. after reasembling the gun i can't adjust the regulator its ****ing stuck all the way down to the e-clip inside the adjustment. took **** loads of anti-seize to free it. so put it back the way it was time the bolt with the feedneck, and back block being a paper-thin gap between housing and back-block, still sounds ****ty and won't fire at all 3 trigger pull then a lod crack of air out the barrel, and this is as far as i got other than trying to adjust the valve thinking it was a valve problem.

I have no clue, please someone help it maybe a timing problem or malfunctioning part or multiple part failure, but before i call it a POS and sell it for parts/scrap would like to have some help.

Hope you guys can help.

Thanks
