MRA V1 Match Nitride AR-15 Barrel 223 Wylde
The Maple Ridge Armoury V1 Match Nitride AR-15 barrel is precision CNC machined in Canada from premium, GBQ 4140 CMV steel blanks. These button rifled blanks are honed, lapped, and stress relieved. Honing controls bore dimensions down to a tolerance of 0.0001″ and lapping is added quality assurance to ensure a concentric and uniform bore. The blanks are air gauge tested during final inspection to ensure the most exacting tolerances.
All V1 Match Nitride AR-15 barrel have precision cut chambers, gas ports, and an 11 – degree target crown. We use an SPR profile to achieve an optimal balance between harmonic resistance , heat resistance, and weight savings. Our unique deep cut fluting improves air cooling and reduce weight without compromising the integrity of the barrel. The 1/8” twist effectively stabilizes projectiles between 55gr and 77gr and the 223 Wylde chamber safely accepts both 223 Remington and 5.56x45mm NATO cartridges.
All Maple Ridge Armoury V1 Match Nitride AR-15 barrel undergo QPQ Black Nitride heat treatment. This heat treatment provides superior corrosion, wear, and abrasion resistance. Instead of adding material to the bore (like Chrome lining), Nitride treats the existing steel by imbuing nitrogen into the surface of the steel both inside and out. In this way, the Nitride process offers excellent accuracy potential.
