AR PERFORMANCE BARRELS: The high performance barrels we sell will outperform most so called "match grade" barrels.  All barrels are not created equal, the 6.8 barrels we sell (coming soon) are among the best and our 223 Wylde (5.56) are even better.   Better exterior ballistics, terminal performance, accuracy, velocity and long life are all possible with finely tuned chambers and high performance hybrid 5R and 3R rifling in Melonite treated 4150 CMV barrels.

AR PERFORMANCE BOLTS: We sell the strongest AR15 9310 alloy bolts made and several efficient muzzle devices.

THAT EVERY MAN BE ARMED  it's not my tagline, it's yours.

The pacifist is road-kill, the porcupine the fauna of liberty.
