I have a 16" barrel that I'm interested in having cut to 11.5" then threaded to accept a flash suppressor. Does anyone in the Portland area have this ability with a quick turn around time and quality work? I know I can send it out to a number of reputable shops and have it done, but I want this done locally. I also have 3 sections of 12" picatinny rail that I want some machining done on. I'm looking to mill/flatten a 6" section of the ribbing to create a narrower rail - similar to the KAC URX 3.1 rails. I would not be trying to take on this rail project but the weapon being worked on is a PWS which uses proprietary rails and so I'm kind of stuck with modifying what I have. If anyone has access to CNC type milling equipment I would ultimately love to see what would be necessary to create a barrel nut that would be threaded to allow a regular rail to be installed on a PWS to allow a Daniel Defense M4A1 RIS II to be installed. I can pay in parts, gear, ammo, MRE's, cash.... Edit: PM me if you can help out with this - you don't need to be a professional shop, just competent.
