I’ve been trying to sell a 16” Rock MTUish SS barrel, 10 twist with 400 rounds fired. Cut by unknown smith for an AW. It’s cut down from an 18” OPS 3rd model setup to 16.25, but I didn’t decide on a thread pattern before I sold my AW. Threads would clean up the last of the OPS profiling but here’s the deal. If someone will drop a Form 1 on their AW or AT and cut this to about 13”, I will give you the barrel to do it. Just because I dreamed of it and it won’t happen. Just send me pictures when your stamp comes back. If you’re only brave enough to pin and weld I’ll give you a discount, $300 shipped. And remember, you can put the NFA markings on the barrel and not on the receiver.
