I bought my first suppressor, the tax stamp waiting period has begun.
Noob question, ... Do people check the concentricity of their barrel threads with the bore? I have 4 hosts for my 7.62 can; a 5.56 bushmaster, an AR10 A2, a 12.5" Noveske 5.56, and a 10" Noveske blackout. I would hate to have to disassemble all these uppers and ship the barrels off to Adco to be checked. What do you say? Do you have your threading checked before shooting through your can? |

I would hate to have to disassemble all these uppers and ship the barrels off to Adco to be checked. What do you say? Do you have your threading checked before shooting through your can? Noveske barrels are the only ones I know of which AAC will warranty a baffle strike if unchecked. Your A2 and Bushmaster are the two I would check. Since 556 is significantly smaller in diameter than 762 you might get away with it without having to take the upper apart. The difference, though, is that zero shift with a can is affected by how concentric the threads are to the bore. If you were using a 556 can I'd be willing to bet a baffle strike very likely. According to ADCO, the best barrels for concentricity are Noveske, BCM, and Daniel Defense, in that order. I'll be using my 30cal can on a DD 5.56 midlength I just started. The MFG I'm purchasing it from will be able to check the concentricity for me when I'm ready to pick it up. You will probably want zero shift to be minimal with and without the suppressor. Threading by Adco would be the ideal imho. Posted Via AR15.Com Mobile |
