Tacticool22 S&W M&P 15-22 Free Float Handguard Converter Nut

This converter nut replaces the factory barrel nut. The Standard nut leaves a 1/4″ gap, while the Modified nut leaves a 3/32” gap, but also requires permanent modification of your upper. Converter nut has the same 1.25-18 outside thread as most AR-15 uppers, allowing a wide variety of AR-15 barrel nuts and handguards to be mounted to your M&P 15-22. Black hard-coat anodized to a Type III MIL-SPEC specification.
