Product description

2A-Armament introduces the "BALIOS" billet upper and lower receiver sets. These sets have been precision 3-D Machined on Makino A51nx horizontals. By utilizing the 3-D machining process, 2A is able to step away from the standard blocky look found in other sets on the market. The BALIOS set has an aesthetically pleasing look that is augmented by the inspired texturing on the front of the magazine well. Both the upper and lower receivers are equally at home on a standard forged product from other vendors. The flared magazine well aids in rapid reloading, and the tapered transition under the charging handle prevents associated wear patterns from damaging the finish. Machined QD sockets give the shooter an optional point of attachment, and the relocated forward assist puts the controls in a more natural position.
