FAB Defense FX-M4R1022B Ruger 10/22 M4 Chassis Kit Black - Folding GL-CORE Stock

The FAB Defense FX-M4R1022B is an M4-style chassis conversion kit that gives a standard Ruger 10/22 rimfire rifle an adjustable, tactical footprint. The kit is configured for the Ruger 10/22 in both standard and bull-barrel configurations and is finished in black.

At the rear, an adjustable folding GL-CORE stock provides length-of-pull adjustment and folds to the side for compact transport. Up front, the M4-style forend incorporates 1913 MIL-STD Picatinny side and lower rails that allow secure mounting of any picatinny-based accessories.

A textured pistol grip with finger grooves gives positive control of the rifle, while the M4-style layout gives the Ruger 10/22 an AR-platform look and feel. The conversion kit features quick and easy drop-in installation, requiring only basic disassembly of the factory 10/22 stock.
