2A Armament

The 2A Armament BL RAIL M-LOK series was designed as a lightweight rail solution utilizing proven traditional 6061 extrusion and titanium as the foundation. The BL RAIL series of rails features the same lightening cuts found on the popular BALIOS-lite receiver sets. When the two are combined a seamless look is achieved across the top of the firearm. The BL RAIL is just as capable on any quality forged or billet upper receiver offered from other manufacturers as well. By utilizing a titanium barrel nut and an innovative 45 degree mounting system the BL RAIL achieves a solid lockup with the upper receiver. The 2A Armament BL RAIL will ship with a 6AL-4V titanium barrel nut. An optional aluminum barrel nut is offered as a separate item for those looking to save maximum weight on a build. - Made from U.S.A. Certified 6061 Extrusion - U.S.A.
