Hey guys I picked up a used 16 from a fellow member a few weeks back and finally got a change to Trim the Fat off this girl, this is a PMM 10.5" SCAR 16" (including the threads.)
Normal PMM Barrel work with the exception of having to machine a custom tapered Delrin coller Spacer to hold the Barrel in the chuck as there was real flat to clamp onto with the Soft-jaws, Total run out from OD to ID .0005" 1/2x28x.625" deep Threads.
I also machined some of my own different sized Gas screws out of Stainless for this application and will have bot of these services/Parts up on the Site soon if anyone is interested.
