The FAB Defense FXDPRB Double Picatinny Rail transforms standard M16/M4/AR15 handguards into tactical platforms capable of mounting multiple accessories. This dual-rail system eliminates the need for separate rail sections while maintaining the original handguard's profile and functionality.
What Makes This Different
Unlike single-rail solutions that limit mounting options, the FXDPRB features two parallel Picatinny rails that accommodate simultaneous mounting of lights, lasers, grips, and bipods. The clamping mechanism secures to standard handguards without permanent modifications or gunsmithing. Installation requires no special tools and maintains zero once properly torqued to specification.Key Features
