XX-TREME Barrel Co. Premium M4 Contour AR-15 5.56 NATO 16" 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 ordinance-grade 4150 Steel Rockwell Hardness of 32-35 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!
Attached one-thousandths front-to-back straight tolerance. This guarantees shot-after-shot performance, giving you that accuracy you demand.
XX-TREME Barrels will achieve 1 inch at 100 yard accuracy when proper match ammunition & proper installation is used (Sub 1 Inch groups were achieved with an anchored testing rifle. Results may vary depending upon usage. The data provided is an average used from testing 10 barrels at 70 degrees with 62Gr match Nosler loaded ammunition).
