Alpha Wolf barrels establish the benchmark for absolute accuracy and combat reliability. It is the pinnacle of what every other barrel manufacturer strives to be.

Barrel Features:

  • Designed for lead, plated, or jacketed ammunition
  • Certified, stress relieved 416 stainless steel
  • Button rifled, three stage honed bore
  • Industry recognized SBN premium coating (SBN is Salt Bath Nitride, similar to Tennifer)
  • Heat treated to RC 40-42, then SBN coating increases surface hardness to RC 60
  • Exacting tolerances allow for drop in installation
  • Fluting creates path for heat and debris to escape
  • Threaded models come with appropriate thread protector installed

Due to SBN coating we are unable to custom chamber or custom crown Alpha Wolf barrels.

    Worth the wait!!! This is exactly what I had hoped an Alpha Wolf Barrel would be. American Made!!! Outstanding craftsmanship. I believe it to be the best there is.
