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:

• PROUDLY MADE IN THE USA!
• Fits Glock generations 1-4
• 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

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