The SureFire M72 Picatinny Rail Forend is a high-quality Picatinny forend for after-market M16 variants with round handguard cap that replaces the weapon's stock forend allowing the user to mount a variety of accessories. Machined from military specification hard-anodized aluminum, they're stronger, dissipate heat much better,and provide rock-solid weapon fit. These precision rails enable consistent "repeat zero" of any accurately dimensioned devices attached to them, such as SureFire lasers or WeaponLights.
