Description
The MRAD earned its reputation as one of the most respected precision platforms ever built, and the SMR takes that same DNA and strips it down to a focused, single-caliber rifle. SMR stands for Single Mission Rifle, meaning this one comes set up from the factory in .338 Lapua Magnum with no barrel swapping capability. In exchange, you get a slimmer, lighter rifle that trims noticeable weight and length off the standard MRAD while keeping roughly 90 percent parts commonality with its big brother. Barrett backs it with a .75 MOA accuracy guarantee, which in a .338 Lapua means you have the hardware to reach well past a mile.
What Sets the MRAD SMR Apart
The heart of this rifle is the 26 inch fluted, free-floated barrel with a 1:9.4 twist, secured in the aluminum upper receiver with a standard barrel nut. The muzzle is threaded 3/4×24 and wears a suppressor-capable brake, so running a can is straightforward. Up top, a full-length Picatinny rail gives you plenty of real estate for a long-range scope and clip-on accessories. The bolt runs inside an enclosed polymer bolt guide, which keeps the action cycling smooth even when dust and grit would bind a traditional design.
Fixed Stock, Adjustable Fit
Instead of the folding stock on the standard MRAD, the SMR uses a fixed stock that gives you a rock-solid cheek weld and shoulder contact, which helps you stay in the scope and recover faster between shots. It is far from one-size-fits-all though. The cheek piece adjusts vertically and spacers let you dial in length of pull, so you can set it up to fit you properly behind a big magnum. The two-stage match trigger module drops out of the lower for easy adjustment and cleaning, and the whole rifle wears a Flat Dark Earth Cerakote finish that holds up to weather and field abuse.
Feeding the .338 Lapua Magnum SMR
The rifle ships with one 10-round detachable magazine for a 10+1 capacity, and it accepts standard MRAD magazines, so spares are easy to come by. Whether you are shooting ELR matches, ringing steel at distance, or building a dedicated long-range setup, this is a proven platform from a company that supplies precision rifles to military snipers worldwide.

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 and does not have the interchangeable barrel system of the standard MRAD. Its free-floated barrel is held in the upper with a standard barrel nut, and the folding stock is replaced with a fixed one. Those changes make it slimmer and lighter while still sharing about 90 percent of its parts with the standard MRAD.
How accurate is the MRAD SMR in .338 Lapua Magnum?
Barrett backs the MRAD SMR with a .75 MOA accuracy guarantee. Paired with the flat-shooting .338 Lapua Magnum cartridge and the 26 inch fluted match barrel, this rifle is fully capable of hits well beyond 1,500 yards with quality ammunition and a good optic.
Is the Barrett MRAD SMR suppressor ready?
Yes. The 26 inch barrel is threaded 3/4×24 and comes with a suppressor-capable muzzle brake, so you can mount a compatible can directly to the brake or thread a suppressor onto the barrel. That makes it an easy rifle to run quiet without extra gunsmithing.
Can I adjust the stock and trigger on the MRAD SMR fixed stock model?
You can. The fixed stock has a vertically adjustable cheek piece plus spacers for setting length of pull, so you can get a proper fit behind the rifle. The two-stage match trigger module is user adjustable and removes quickly from the lower receiver for tuning and maintenance.
