Developed to improve the performance of the M4 rifle chambered in 5.56 NATO, the 6.8 Remington SPC cartridge provides superior downrange ballistic performance when fired from short barreled rifles. The Rock River Arms Mid-Length A4 gives you the benefits of the 6.8 Remington SPC with the familiar controls of the AR pattern rifle. Featuring a 16" chrome molybdenum barrel with a 1:9 twist, a 5/8"-24 TPI A2 flash hider, mid-length gas system and mid-length handguard, an A2 front sight, a flat-top optic ready forged A4 upper receiver and forged LAR-15M lower, and a 6-position stock and A2 pistol grip, the Rock River A4 will be as familiar as an old friend. When paired with an appropriate rear sight, this rifle will be perfect for any task from home defense to varmint hunting.
