The Maple Ridge Armoury Match 5R Cerakote AR-10 barrel is precision CNC machined from premium, Canadian made, GBQ 416R Stainless Steel blanks. The blanks are honed and hand lapped and then button cut rifled with 5R rifling to provide us with the absolute best possible foundation from which to machine and assemble all Maple Ridge Armoury barrels.
All MRA Match 5R Cerakote barrels have precision cut chambers, gas ports, and an 11 degree target crown . The M118LR chamber will safely accept both 308 Win and 7.62×51 NATO cartridges and effectively accommodate the ogive of the Sierrra 168 and 175 HPBT cartridges loaded near or at magazine length. The 1:11.25″ twist rate will effectively stabilize projectiles between 147 and 175 grains achieving optimal performance with the heavier projectiles in the spectrum. We use an SPR profile to achieve a balance between harmonic resistance , heat resistance, and weight savings. The unique deep cut fluting presents greater barrel surface area to facilitate improved air cooling while dramatically reducing weight without compromising the overall rigidity of the barrel.
All Match 5R Stainless AR-10 barrels are made from GBQ 416R Stainless Steel. This provides superior corrosion resistance while offering the greatest accuracy potential possible. Instead of adding material to the bore (like Chrome lining) which is often uneven in application, the bore on these barrels is precisely cut as it came from the factory thus maintaining the ultra tight tolerances leading to extreme accuracy.
The Cerakote is professionally applied to the exterior of the barrel enhancing the wear and corrosion resistance.
