The M6A2™ rifle is a standard carbine available in various barrel lengths and in either 5.56mm NATO or 6.8mm SPC. The M6A2™ rifle is ideal for those who utilize optical sights as it employs a low- profile gas block. There is no A-frame front sight to obscure the field of view of the optical device. The M6A2™ rifle also features a longer midlength free float rail system with a removable return-to-zero top. Any M4 MIL Std 1913 accessory can be mounted to the rail, and because the rail has a monolithic profile, you can bridge devices from the receiver to the rail seamlessly. The longer rail also affords more 1913 “real estate” to mount your accessories.
