So I’m in the process of registering/purchasing my first SBR and suppressor. I’ve ordered a KAC NT4, and I’ve had my LMT lower engraved with my name and city/state.
I haven’t ordered an upper yet, and since this is going to be a MK18 Mod0 clone, and the lower is LMT, I plan on using an LMT upper.
My question is… What is the best route to take to ensure the barrel threads are concentric? I am either going to just order an LMT 10.5 and hope for the best, or order a 14.5/16 and send it to ADCO and have them cut it down to 10.5, and open the gas port to whatever LMT’s 10.5 are, which I believe are roughly .068-.070.
Since this is my first SBR/Suppressor, I could just be worrying about nothing, but I figure it’s better to be cautious now. Perhaps I’ve seen too many threads with “baffle strike” in the title, and perhaps there is a strong trend of lower quality manufacturers in those threads, but I’d rather not shell out all this money and then have a baffle strike when it is only an extra $50 roughly, to ensure the threads are perfect.
