Rifling is a series of spiral grooves cut or formed into the bore that cause the bullet to rotate in flight. The bore is the inside diameter of the barrel, consisting of rifling. At the breech end of the barrel is the chamber, a compartment cut to accept a specific cartridge. The rearmost part of the barrel is called the breech. In AR-15 barrels, the muzzle is typically threaded to accept a muzzle device, such as a flash suppressor or recoil compensator. The front of the barrel, from which the bullet exits, is the muzzle. Put simply, a barrel is a metal tube through which a projectile is fired. You’ll have to determine for yourself whether these advantages are worth the additional expense. However, these reductions are costly - almost twice as expensive as other, more traditional designs. The company also advertises its barrels as further reducing harmonic vibration, which may improve accuracy.

In addition to reducing weight, the composite design dissipates heat more efficiently than traditional steel barrels. The carbon fiber, which is both strong and stiff, allows for a significant weight reduction - up to 64% compared with all-steel barrels of the same length and profile. A 416R stainless-steel barrel blank, PROOF Research turns down the outside profile and encircles the barrel in carbon fiber. PROOF Research offers a special-purpose barrel on the more expensive side, featuring the hybrid. The company also offers 11.3” barrels for pistols and short-barreled rifle builds as well as longer barrels for precision shooting. 223 Wylde chamber designs and manufactures every barrel using mil-spec 4150 CMV. These increase corrosion resistance, protecting the barrel from rust and ensuring that it’s ready for any environment.īallistic Advantage offers its range of barrels in both 5.56mm and. In addition to the unique profile, Ballistic Advantage applies a nickel-boron coating to the barrel extension and a QPQ (quench, polish, quench) nitrocarburizing treatment to the barrel. This change reduces weight and eliminates asymmetry that may adversely affect accuracy. The Hanson barrel features a taper from the gas block journal to the muzzle, eliminating the shoulder common to government-profile barrels. Ballistic Advantage manufactures rifle barrels for various applications, but one of the most interesting innovations this company has devised is the Hanson barrel.
