All our barrels are hand lapped using real lead for better accuracy, easier cleaning and eliminating the need for barrel break-in. The HBar barrel stays cooler round after round (better heat dissipation).
We properly crown our barrels, insuring that the bullet exist point is even, thus improving accuracy.
Our barrel chambers are completely polished to insure you do not experience failures to eject when using quality ammunition.
Bolts have the gas key properly staked. Additionally, our bolts have David Tubb Extractor and Ejector Springs installed and extractor spring strength is tested to make sure it performs flawlessly. Bolt rings are rotated individually and offset from each other.
Our upper receivers are carefully lapped to insure proper mating between the barrel and the upper.
Our rifles have the head space measured and are test fired to insure smooth cycling and proper barrel/upper alignment.
All steel parts are 100% integrity tested beyond the MPI (Magnetic Particle Inspected) standard. Using our proprietary non-magnetic high current material resistance testing we can detect structural defects deep within the parts such as internal fractures and metal density weaknesses as opposed to MPI which only checks for surface defects.
You will not find a better quality upper in this price range anywhere!
