Quantity in Stock: Right To Bear 10.5" GOV Profile Barrel 5.56 (Carbine Length)
This 5.56 chambered 10.5 inch Government Profile Barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and QPQ coated M4 feed ramp extension.
Quench Polish Quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is also known by the brand names of H&M Blacknitride+ (black nitride), Tufftride, Tenifer, or Melonite. QPQ is a huge improvement over chrome lined barrels. Unlike chrome lining, where the chrome is built up on the surface, QPQ converts the surface without the risk of dimensional build up. QPQ makes your gun’s metal 10 times stronger than it was originally, increases the velocity of your barrel by a few hundred feet-per-second, and slickens the surface to make your gun extremely lubricated.
Depending on your state and local laws, you could use this barrel with either a pistol, or a lower receiver that is a registered SBR. Possession of this barrel along with a non-NFA lower receiver may be prohibited. We are not lawyers and the above information is not legal advice. Make sure you understand the most up to date federal, state, and local laws before proceeding with this product.
