This beautiful rifle from the Midwest fills the need for an affordable AR that you can trust to be built right. Chambered in the popular .308 Winchester, these GLFA AR10 rifles feature an 18" barrel in your choice of a beautiful 416r stainless steel or an ultra-smooth 4150 CRMOV black nitride finish with a 1:10 twist. These barrels have 5R rifling, as well as being double thermally stress-relieved and air-gauged. The .308 Winchester caliber is a phenomenal all-purpose cartridge, from target shooting at the static range, long-distance precision shooting, or hunting, .308 packs a heavy punch. The heavy barrel incorporates a rifle-length gas tube, with 0.750 Gas Block. The barrel is threaded in 5/8x24 and is fitted with a ported compensator hand tightened to the firearm. Each barrel is surrounded by a 15.25" 6061 aluminum M-Lok handguard with a disrupted picatinny rail on top, allowing you to both attach the different accessories you may require and C-clamp the weapon to help increase stability.
