Description
The Single Mission Rifle takes everything that made the MRAD a legend in the precision world and strips it down to one job. Where the standard MRAD is built around swappable barrels and caliber flexibility, the SMR arrives from the factory set up in .300 PRC and stays that way. That focus pays off in a rifle that runs nearly 2.5 pounds lighter and an inch shorter than its multi-caliber sibling, while keeping about 90 percent parts commonality with the standard MRAD. You also keep the accuracy that put this platform on the map, with Barrett standing behind .75 MOA performance.
What Sets the MRAD SMR Apart
The heart of this rifle is a 26-inch fluted match barrel with a 1:8 twist, fully free floated and secured in the upper receiver with a standard barrel nut. That monolithic upper is machined from 7000-series aluminum and wears a full-length M1913 top rail with built-in taper, so mounting glass for long range work is straightforward. The bolt rides in an enclosed polymer bolt guide that keeps the action running smooth even when dust and grit would bind a tighter traditional design. Down in the lower, the match-grade trigger module is fully adjustable and drops out without tools, and the thumb safety can be set up for left or right hand operation.
Built for Steady Shooting in .300 PRC
The fixed, non-folding stock gives you a rock solid rear contact point with less flex than a folder, which helps you settle back into position faster between shots. A vertically adjustable cheek piece and length of pull spacers let you dial the fit to your build and your optic height. Chambered in .300 PRC, this rifle is right at home stretching past 1,000 yards, whether that means ELR matches, steel at distance, or big country hunting where wind calls matter. The Flat Dark Earth Cerakote finish looks sharp and holds up to field use, and the included 10-round magazine feeds through an ambidextrous release you can work without breaking your grip. The muzzle is suppressor capable, so adding a can later is an easy upgrade.

Frequently Asked Questions
What is the difference between the Barrett MRAD SMR and the standard MRAD?
The SMR, or Single Mission Rifle, is factory set in one caliber rather than using the standard MRAD's user-changeable barrel system, and it swaps the folding stock for a fixed one. Those changes trim close to 2.5 pounds of weight and an inch of overall length. It still shares roughly 90 percent of its parts with the standard MRAD and carries the same .75 MOA accuracy standard.
Can the barrel on the MRAD SMR be swapped to another caliber?
No, and that is the whole point of the design. The SMR is configured from the factory in .300 PRC only, with the free floated barrel held in the upper receiver by a standard barrel nut instead of the quick-change system on the regular MRAD. If you want caliber flexibility, the standard MRAD is the better pick.
Is the Barrett MRAD SMR suppressor ready?
Yes. The SMR's muzzle brake is designed to be suppressor capable, so you can mount a compatible can directly to it. That makes adding a suppressor down the road a simple bolt-on upgrade rather than a gunsmith project.
How adjustable is the fixed stock on this rifle?
While the stock does not fold, it is far from one-size-fits-all. It features a vertically adjustable cheek piece to line your eye up with your optic, plus separate spacers for setting length of pull. The rigid, non-folding design also gives you a more solid rear contact point for quicker recovery between shots.
