Availability: Out of stock
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.
