The Maple Ridge Armoury Match 5R Stainless AR-10 barrel is precision CNC machined in Canada from premium, GBQ 416R stainless steel blanks. These button rifled blanks are honed, lapped, and stress relieved providing the best foundation to machine and assemble our line of premium barrels. All MRA Match 5R Stainless AR-10 barrels are backed by our 1 MOA or better accuracy guarantee and lifetime warranty.
All MRA Match 5R Stainless AR-10 barrels have precision cut chambers, gas ports, and an 11 – degree target crown . The 1:8″ twist rate will effectively stabilize the greatest range of 6.5mm projectiles common to the 6.5 Creedmoor cartridge. We use an SPR profile to achieve an optimal 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. We also offer a Tapered Pencil profile to achieve the greatest possible weight savings while maintaining structural integrity.
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.
