AR15 ARC Stock

A1-length buttstock for low prone shooting with 10- and 20-round magazines. Fits AR-15 and Airsoft M4 gas blowback (GBB) rifles. Universal fit for rifle, commercial carbine, and mil-spec carbine buffer tubes. Flats on underside for installation of Picatinny rails, monopods, and sling hardware.

For installation on rifle buffer tubes, an upper buttplate screw is required and might need to be shortened for full buffer travel.

For installation on carbine buffer tubes, you will need a nylon- or brass-tipped 1/4"-20 set screw and long hex wrench. Apply pressure while driving set screw to form threads.

A standard grip screw, washer, and lock washer are also required. You might need to elongate the grip screw hole in the stock for proper fit.

UPDATED 12/21/2018: Fill 1mm gap forward of grip, relocated selector spring hole and grip screw, added ambi selector lever cutouts, and narrowed grip mount. Please post a comment or message me if the updated models improve or worsen the fit.
