LBE Unlimited Cold Hammer Forged Barrel Features The LBE Unlimited Cold Hammer Forged Barrel is manufactured using the cold hammer forging process a method known for producing a stronger more consistent bore than button or cut rifling alone. This construction supports long-term durability and helps the barrel maintain accuracy through extended use which matters for anyone building a rifle meant to see real round counts. The 1:7 twist rate is a versatile choice for the 5.56x45mm chambering stabilizing everything from lighter 55 grain bullets up through heavier 77 grain match loads. A melonite finish over the steel barrel adds corrosion resistance and a durable black exterior that stands up to field use. This barrel is built with a mid-length gas system and a 14.5 inch overall length a common combination for AR-15 builders looking for a balance of handling and reliable cycling. The muzzle is threaded 1/2x28 giving the builder the option to run a muzzle brake comp or suppressor mount without additional gunsmithing. LBE Unlimited designed this barrel to be a precise drop-in fit for standard AR-platform upper receivers keeping installation straightforward for a home builder or armorer. Whether replacing a worn factory barrel or finishing a custom upper this barrel delivers the accuracy and reliability expected from a cold hammer forged AR-15 barrel.
