2a Handguard by Phil, October 21, 2017
I have a 15in handguard and absolutely love it. When I heard that the gen1 handguards were discontinued I jumped on the chance to get two 10in guards. I personally prefer the look of the gen1s to the gen2s. Overall great product and lightweight.

2A Armament Balios Lite Rail by wessmith19, July 27, 2017
Exceptional rail. Very lightweight which is the main reason I chose this rail system. If you're looking to build a lightweight AR system I would give 2A Armament a look. These guys build top notch accessories.

Product Info for 2A Armament Bl-Rail M-Lok Black Titanium Barrel Nut Ar-15

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.image
