The SureFire M69 Rail Mount Assembly is a high-quality Picatinny forend for the Remington 870 shotgun that replaces the weapon’s stock forend allowing the user to mount a variety of accessories. Machined from military specification hard-anodized aluminum, the M69’s precision dimensioning allows for consistent “repeat zero” positioning when matched to an accurately dimensioned mounting device such as those found on SureFire WeaponLights.
