Tactical Kinetics Barrel AR-15 6.5 Grendel II 16.25in 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. Keep in mind that headspace component selection assembly methods external variables such as the shooter environmental conditions and ammunition will all have an impact on group sizes. TK only recommends that you use factory new SAAMI approved ammunition in TK barrels. Tactical Kinetics stands behind their barrels performing 1 MOA (or better) when Match Grade ammo is used. Tactical Kinetics AR15 barrels are then coated in Nitride or Ferritic Nitrocarburizing resulting in significantly improved surface properties on ferrous metal parts while maintaining dimensional and shape stability. Nitride yields increased wear resistance improved fatigue strength better corrosion resistance improved lubricity and enhanced cosmetic appeal.
