Bravo Company Manufacturing BCM MK12 Mod 0-A5
Product Review: BCM MK12 Mod 0-A5 Precision Rifle
The AR has been the one of the most ubiquitous rifles in the United States in part because of the versatile of the system. With the large and diverse aftermarket parts support an individual can build an AR to fit one of many specializations. From a jack-of-all-trades rifle, to a personal defense weapon build the options are endless. One particular build genre that has become popular is the precision AR. Precision AR’s have been around for a long time but undoubtedly all draw their linage from the military’s Mark 12 SPR (Special Purpose Rifle).
For those unaware the Mark 12 SPR was a rifle built by the US Naval Surface Warfare Center Crane Division for use by SOCOM units. The rifles built by the military have seen action in recent conflicts in the Middle East. While the exact history of the rifle is unclear, we do know that the rifles were developed as a designated marksman rifle, to have a greater effective range than the M4. In addition, we know that SPR originally stood for special purpose receiver. The initial goal was to have a separate receiver, which a solider could replace, on the ground. The rifles soon grew to full builds and the nomenclature changed to special purpose rifle, which is what is still used today. Over the course of the rifles use they went through several variations (MOD 0, MOD 1 and MOD H) some of which overlapped one another. There is an entire segment of the 2A community dedicated to these rifles, with fierce debate over the exact specs for builds.
While building a rifle can be an enjoyable and challenging experience, some manufactures have begun to build rifles in the same spirit as the Mk 12. One in particular which maintains much of the original parts is the Bravo Company Machine MK12 Mod 0-A5. While the above mentioned historians will want me to note that this rifle by BCM is not an exact match to the militaries Mk12 Mod 0 it does follow many of the original specifications. Regardless of the adherence to some military approved spec list, the rifle does boast a substantial list of high end parts.
This rifle features an 18” 410 1-8’ twist Stainless Steel barrel chambered in 5.56 x45mm NATO. This barrel configuration will give a little more velocity allowing the shooter to reach out further and also with the 1-8’ twist will give the greatest flexibility with bullet weights from the 55 gr. ball to the long range 69 gr. match king. The receivers are forged from 7075-T6 aluminum, the standard for high end ARs, and then coated to military specification with type II anodizing. The rifle utilizes a 15” long handguard from PRI Inc. PRI handguards are carbon fiber and have a unique feature of having a rail that is bolted to both the upper receiver and the handguard. This configuration creates a rigid system that allows the end user to mount optics with traditional rings as opposed to the offset mounts, which have become prolific in the market. The rifle also uses PRI Inc.’s folding backup sights which are considered some of the best in the industry.5 From BCM the rifles is comes in solid black or my preference flat dark earth (FDE). The complete weight of the system (without optic) is approximately 9 pounds which a tad on the heavier side for an AR but for a precision oriented rifle its no problem as the extra weight will assist in stabilizing the system for the longer range engagements.
Overall BCM is a top-notch firearms manufacture and you can see that in the build quality of this rifle. The rifle has so many features it’s a challenge to list them all in a single article without it seeming like rambling so the entire spec sheet is below for those interested in some of the important but often overlooked details in rifle such as magnetic particle inspected bolts.
For those looking for a bit of history and a fantastic light precision rifle this is the ticket and I would completely recommend it.
