getting back on track, anyone got a pic of a FSB they had ADCO shave down to fit under a rail? Im thinking about having them do that for me, $5 cheaper on the service and saves the cost of a new gas block....
Amazing that one can patent a golf ball pattern to a rifle barrel.

I never would have guessed. Learn something new everyday.

Another +1 for Adco They recieved my upper on Monday for pinning and had it back in my hands by Friday! Excellent work![]()
I know I've already posted above, but I have just came back from zeroing my ADCO-pinned BCM and I thought I should add a few words.
One thing that's not mentioned is the fact that ADCO also crowns/threads bbl, when they do length reduction/pinning job, and crowning and threading are excellent. Before I had my 16 inch BCM cut, I shot it for accuracy - 10 rounds, and saved remainder 10 from that box. When cutdown bbl came back, I shot those remaining 10 rounds and the accuracy started to approach my SS Noveske. Not quite, but close. It could be that bbl became more rigid, but I think it had something to do with crowning.
I recalled it today when I was zeroing Aimpoint on that upper. I didn't take pictures, so you just have to imagine 4 rounds touching each other just left of 10-ring. After adjustment for windage, fifth round drilled 10 ring. Chrome-lined bbl, 2MOA optic, commercial training ammo (55 gr PMC), PMAG as monopod, no rear bags - sub-MOA group. The only "precision" component was Geiselle trigger and, I firmly believe, ADCO crown.
Adco did great work on my LMT. Good communications keeping me appraised of the status of the work too.
