Good question Deja
I dunno. I can live with a few MOA.
I think I might have found a small problem with the Douglas barrel/Coastal LRT combo. It seems even when "gorilla" tight the rear of the can is a tiny fraction from seating on the shoulder of the barrel.
And... the threads are a little looser than the other two barrels. When nearly fully threaded on, the suppressor wobbles more than the others.
Maybe a shim is in order.
