Bravo Company Manufacturing, better known as BCM, builds AR-15 rifles and parts in Hartland, Wisconsin. The Mk12 Mod0-A5 is BCM's precision rifle built on the Mk12 Mod 0 pattern, here in Flat Dark Earth, BCM part number 862-MK12-5-FDE.
It's chambered in 5.56 NATO. The 18-inch 410 stainless steel barrel is in the Mk12 contour, button rifled and hand lapped, with a black IonBond finish and a 1-in-8 twist. A 1-in-8 twist handles the heavier match bullets that suit longer shots. The gas system is rifle length, which gives a softer, smoother push on a barrel this long.
A Mk12 compensator sits at the muzzle. The handguard is a PRI Gen III 12-inch carbon fiber tube in Flat Dark Earth, and a PRI folding front sight base and ARMS folding rear sight give you iron sights ready if your optic goes down.
The A5 in the name refers to the A5 receiver extension and buffer, a slightly longer system that many shooters find smoother. The rifle has BCM's PNT trigger, a BCM Gunfighter grip and a BCM Mod 4 charging handle. The receivers are forged 7075-T6 aluminum, hardcoat anodized, and it comes with a 30-round magazine.
It measures about 35.5 to 39.5 inches long and weighs about 8.9 pounds (4.06 kilograms).
If you want a Mk12-style 18-inch precision AR from a maker known for hard-use rifles, this BCM is well worth a look.
