MRA 18.6” Match Straight Flute Barrel
Maple Ridge Armoury Match Series barrels are precision CNC machined from 416R stainless steel and completely stress relieved . The rifling is button cut and air gauged to within 0.0005” for the entire length of the barrel and the bore must measure 0.0005″ concentric to the diameter of the barrel. All barrels have precision cut chambers, gas ports, and recessed 90 – degree crown . We use a Medium or SPR profile to achieve an optimal balance between harmonic resistance , heat resistance, and weight savings. The unique deep cut straight or spiral fluting presents greater barrel surface area to facilitate improved air cooling while dramatically reducing weight without compromising the overall rigidity of the barrel.
