The Brownells BRN-22 receiver is based off of the Ruger 10/22. It has a monolithic scope base and is mahcined from billet 6061 aluminum. The end result is a lightweight rugged receiver. This BRN-22 is a take down model with an overmolded rubberized thumbhole stock. The bull barrel is threaded and has a compensator already attached to it. This would be an ideal competition or backpack .22LR plinker.
