Mossberg & Sons is shooting at another platform in 3-Gun with the release of a rifle tailored for the competition. Here is the Mossberg MMR Pro Rifle.
There are few things that hold a candle to the non-stop action of 3-Gun. The multi-platform competition demands the most out of shooters, requiring a deft mixture of speed, precision and awareness.
Mossberg & Sons has long been a part of this fast-and-furious run and gun, producing the preferred shotguns of many competitors. And the Connecticut-based gunmaker is shooting to stake another claim in the popular and still fast-growing shooting sport with the newest release in its MMR (Mossberg Modern Rifle) line.
The MMR Pro Rifle appears to have all the bells and whistles the competitive minded look for in a rifle that will gun for the gold. Which should come as a little surprise, given five-time 3-Gun Champion Jerry Miculeck had input in the AR-style rifle’s design.
Miculeck’s heaviest influence came in the trigger that bears his name. The JM Pro Drop-In Match Trigger offers shooters a smooth pull that breaks crisp and clean at 4 pounds. It has been designed to eliminate all creep and offers a desirable extra in its user-adjustable overtravel. In short, the trigger should do everything to keep a shooter on target during the shot and get them reset to take the next in a blink of an eye.
The 35.75-inch rifle, chambered in the standard .223 Rem./5.56x45mm NATO, is deck out with Mossberg’s revamped AR furniture. What this mainly pertains to is the company utilizing the M-LOK modular mounting system on its handguard. The cutouts on the slim 15-inch handguard should be a nice addition, given the system tends to hold accessories more firmly, while allowing quick switchouts.
The buttstock of the direct-impingement gas system rifle is adjustable to six positions, providing an ample 3.25 inches of adjustment to length of pull. The LOP can be fine tuned with Mossberg’s FLEX recoil pad system with three different pad thicknesses.
The MMR Pro Rifle is outfitted with an 18-inch stainless steel barrel, bored with an 1:8-in. twist rate, which should stabilize a wide variety of bullet weights. The free-floating barrel is topped off with SilencerCo’s ARS 3-port muzzle break, eliminating muzzle rise and making the rifle more controllable shot to shot. The break can be removed and switched out for suppressors with a 1/2×28 thread.
Mossberg has rounded out the 7-pound rifle with an ambidextrous charging handle, making it righty and lefty compatible. And it has outfitted it with a forward assist, a feature not found on the MMR Carbine (base model).
In the scheme of rifles designed for 3-Gun, Mossberg has made it easy to get behind the trigger of the MMR Pro Rifle, price wise. The gun is a value in terms of competitive rifles, with an MSRP is $1,393.
