Tactical Kinetics Barrel AR-15 .223 Wylde 12.5in Medium Contour Mid-Length Gas 1-8 Twist Black Nitride

Tactical Kinetics Barrel AR-15 .223 Wylde 12.5in Medium Contour Mid-Length Gas 1-8 Twist Black Nitride. Every barrel is precision instrument-inspected for absolute straightness and air gauged for maximum uniformity yielding the highest accuracy possible. Land and groove tolerance from breech to muzzle can vary only .0001" for the best concentricity. When using factory loaded SAAMI approved Match Grade ammunition you can expect 1 MOA level accuracy (or better) out of TK AR15 barrels at 100 yards.
