Description
The Maple Ridge Armoury Match 5R Stainless AR-15 barrel is precision CNC machined in Canada from premium, GBQ 416R stainless 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 MRA Match 5R Stainless 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 Match 5R Stainless AR-15 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.
