Premium Socom Contour  AR-15 5.56 Nato 
10.5" 1:7 Twist Phosphate Finished Barrel

XX-TREME Barrel Company prides itself on cryo-treating every barrel, giving the shooter shot-after-shot performance even when the barrel gets hot. Cryo Treatment eliminates the memory the steel has when the barrel gets hot. Made from premium ordnance-grade 4150 with a Steel Rockwell Hardness of 28-32 gives this barrel exceptional long life, surpassing most AR-15 barrels on the market. Each barrel is target crowned & threaded to 1/2-28 TPI to accept all muzzle devices available.

Features Tru-Center Machining Technology Laser-Assisted Bore Centering. This gives each barrel a true centering so silencers are safe with no risk of baffle strikes. A must for silencer owners!

Guaranteed shot-after-shot performance.
