New Gear: Mossberg JM Pro Drop-In Match Trigger

JM Pro Drop-In Match Trigger - 1

Affordable and simple to install, Mossberg‘s JM Pro Drop-In Match Trigger offers shooters a way to quickly upgrade their AR's accuracy potential.

It’s been said far and wide, over and over — trigger upgrades are one of the quickest routes to accuracy. This is especially true when it comes to stock AR-style rifles.

The Mil-Spec triggers typically found in the off-the-shelf variety of America’s favorite rifle leave much to be desired. They’re squishy on the take-up, gravelly once they hit the wall, and their overtravel can go coast to coast. Luckily, in the modern day, this is one of the simplest problems to rectify with a head-spinning array of trigger options that will improve the accuracy potential of a rifle the minute they’re installed.

Mossberg is one of the most recent entrants to this end of the market, recently releasing the trigger group found in a number of the models from its redesigned AR line (MMR rifles) as a standalone. The JM Pro Drop-In Match Trigger offers shooters what appears to be an economical and functional option to upgrade any Mil-Spec AR-15 or AR-10 rifle with .154-inch trigger and hammer pin holes.

The trigger was designed with the input of 3-Gun world champion Jerry Miculek (the JM in the name) and has been engineered to offer a crisp, creep-free break. The pull weight is factory set at 4 pounds and features user-adjustable overtravel. The latter feature should help make a rifle a faster shooter, creating a more efficient trigger pull, not to mention one more comfortable for the user.

Mossberg’s JM Pro Drop-In Match Trigger is also priced to be within reach of most shooters. With an MSRP of $161, the upgrade comes in on the lower end of the drop-in market's price scale.
