Aero Upper lower set, Jp industries 1:11.25 twist cryogenically treated barrel. Trigger tech trigger, adjustable gas block. Magpul Adjustable stock. Currently setup for suppressed fire with FMOS bolt carrier. I also have the LMOS BOLT CARRIER AND Spring kit along with various buffer weights. Really cool rifle , fairly lightweight, with everything in the package it can be setup to run about anything. Currently running Vortex Sparc red dot with riser. I am also interested in trades for 308 WIN bolt action rifles with threaded barrels. Also interested in long range setups and frankly anything of equivalent value. High end optics, higher end lever guns , etc
