Modern Series Barrels
Made from the same 41V50 Chrome Moly Vanadium steel used in MIL-SPEC barrels, these barrels are designed and manufactured to a level far surpassing MIL-SPEC. After being precision cut, each barrel is fully treated with a corrosion resistant QPQ salt bath nitride finish. This finish does not alter the dimensions of the barrel which allows the precision tolerances to carry through to the finished product.
By treating the barrel and the M4 barrel extension separately prior to installation, proper torque value is maintained throughout the life of the barrel. Muzzles feature a flat crown with chamfer and threading. In the end, a Modern Series barrel is an economically priced barrel attached to an MOA guarantee.
