A Collection of Durable, Duty-Ready AR-15 Barrels

Sons of Liberty Gunworks makes some of the best combat-ready barrels on the market, and they're durable and versatile enough to run in a variety of configurations, especially suppressed or unsuppressed, without the need for an adjustable gas block. The company's Combat Grade AR-15 Barrels are duty ready and available in a variety of configurations for the AR-15 enthusiast or professional user.

For those building or upgrading rifles chambered in 5.56 NATO, the SOLGW Combat Grade Barrel lineup can be had with a carbine-length gas system in 10.5- or 11.5-inch lengths. For those looking for a mid-length gas system, barrel lengths are available in 13.7-, 14.5- and 16-inch lengths. The Combat Grade barrel is also available in 300 BLK, which features a pistol-length gas system and an overall length of 9 inches.
