I've got a 9mm AR barrel that I need cut back to about 7", and threaded 3/4-10 like an M11/9.
I've got a suppressor for my Cobray M11/9, and I'd like to use it on an SBR AR with a 9mm kit. It's got to be as close to perfect as possible, the can is 11" long. I plan to use a freefloat tube around the rear portion of the can.
What would this cost and what kind of time would be required? I can't send the suppressor along since it's not in my possession yet (I'm still waiting on paperwork), but I have a threaded Cobray muzzle extension that I can ship with the barrel to double check the threads.
Adapters are available for 1/2-28 to 3/4-10, and I can get the barrel threaded 1/2-28 locally. If you think this is a better option let me know also. I'd just really prefer to have the existing barrel machined to the same specs as the Cobray barrel.
