Lead and Steel Match Grade 5.56 NATO 11.5" Threaded AR-15 Barrel 1:7 Twist

Lead and Steel Match Grade Features The Lead and Steel Match Grade barrel is machined from 4150 Chrome Moly Vanadium steel a material prized for its strength and fatigue resistance under the heat and pressure of repeated firing. A QPQ black nitride finish is applied over that steel providing exceptional corrosion resistance and a long service life compared to standard phosphate coatings. Chambered in 5.56 NATO with a 1:7 twist rate this barrel stabilizes a wide range of bullet weights from lighter varmint loads up through heavier match projectiles. The government profile contour adds mass forward of the chamber for added rigidity helping the barrel hold its accuracy as it heats up during sustained strings of fire. A dimpled barrel surface ensures the gas block aligns and locks into the correct position every time preventing the gas port misalignment that can cause cycling issues on an AR-15 build. Built around a carbine-length gas system with a 0.750 gas block diameter and M4 feed ramps this 11.5 inch barrel is designed to integrate cleanly with standard AR-15 upper receivers and bolt carrier groups. Threaded 1/2x28 it is ready to accept a muzzle device or suppressor without further machining. Weighing 20.5 ounces and sub-MOA guaranteed when paired with MK262 ammunition the Lead and Steel Match Grade barrel is available for sale at ARMSAGORA for builders who want precision in a compact carbine package.
