We got some trigger time with the Mossberg MMR Pro at last year’s Athlon Outdoors Rendezvous, and we came away impressed. Purpose-built for the sport of 3-Gun, the MMR Pro delivers an out-of-the-box, match-ready rifle. Moreover, accurate and affordable, this rifle will serve well as a ranch or truck gun, or for simply fun shooting at the range.

Upgraded features begin with an adjustable drop-in trigger designed by renowned 3-Gun champion Jerry Miculek. Also, with a crisp, creep-free break, the adjustment ranges from 3 to 6 pounds. The JM Pro Adjustable Match Trigger fits all standard AR-15 and AR-10 lowers, utilizing a .154-inch trigger and hammer pin holes. Additionally, the trigger adjusts for overtravel. Moreover, the unit is available as an aftermarket accessory as well.

The rifle sports an 18-inch, 416 stainless steel barrel. It also comes with a SilencerCo 3-port muzzlebrake that is compatible with suppressors. Additionally, Mossberg’s own 15-inch slim-profile forend utilizes M-LOK attachment. A full-length top rail also provides additional mounting surface.

Mossberg upgraded several components on the MMR Pro, including the charging handle. The also rifle comes standard with an AXS Raptor ambidextrous model, adding to its versatility.

Finally, a six-position stock includes Mossberg’s FLEX System recoil pad. The FLEX includes three interchangeable pads, in differing thicknesses, giving even more range in length-of-pull adjustments.
