This stock system allows the use of AR-15 type optics and accessories. Includes an upper receiver housing with integrated picatinny rail, lower receiver housing with pistol grip and storage compartments, and a free float handguard with top and bottom picatinny rails. Also included is an extended magazine release. The stock system will work with bull barrel, however the muzzle device will NOT work with bull barrels.
Important Note: Stocks and barrels designed for the Ruger 22 Charger pistol may not be used on a Ruger 10/22 rifle since the installation converts the 10/22 into a pistol or short barreled rifle and violates federal law.
