Ive seen countless Ar's with the ops inc brake and collar used with their 12th model can but none of a heavy contour (MTU M24 ~#7 or the like) bolt gun that has been contoured to fit the same brake and suppressor. I understand the collar is substituted by machining the barrel to the correct dimensions if the diameter is sufficient but I could be wrong on that.
And I have seen heavy barrel bolt guns with the 12th attached but if anyone has anymore of those feel free to post em
And I only ask because when (if possible) I order one I will send my gun to get threaded and contoured while im waiting so when the big day comes it'll be ready, but seeing how I don't really know when that big day might come I'm curious to see what my ole gun will look like in the meantime...
Much appreciated if anyone has any.
