The Barrett MRAD SMR .300 Win Mag 26″ Fixed Stock is a bolt-action precision rifle built for shooters who demand absolute accuracy without excess weight or bulk. Chambered in .300 Winchester Magnum, this single-caliber configuration delivers the long-range performance and parts commonality of the MRAD family in a slimmer, fixed-stock package. The 26-inch fluted barrel is free-floated and secured by a standard barrel nut, ensuring consistent harmonics shot after shot. A full-length handguard provides ample real estate for bipods and accessories, while the vertically adjustable cheekpiece and length-of-pull spacers allow precise fit without tools.

Key Features
- Free-Floated Fluted Barrel: The 26-inch barrel is fluted to reduce weight and improve heat dissipation while remaining free-floated. This eliminates contact points that could shift point of impact under sustained fire.
- Fixed Stock with Adjustable Cheekpiece & LOP: The tungsten-grey stock does not fold, reducing complexity and weight. The cheekpiece adjusts vertically, and LOP spacers let you dial in fit for prone or barricade positions without tools.
- Full-Length Handguard: Extends forward to support bipods, lasers, and night vision. The rigid design maintains zero on accessories and protects the barrel from contact.
- Single-Caliber MRAD Commonality: Uses the same barrel nut, receiver, and trigger group as other MRAD models. This means spare parts and upgrades transfer directly, simplifying logistics for agencies or individual shooters.
Who It’s For
This rifle is for law enforcement marksmen, military snipers, and serious long-range competitors who need a .300 Win Mag platform that is lighter and more compact than a full-sized MRAD but retains the same accuracy and reliability. It suits operators who do not require a folding stock but want a dedicated, single-purpose precision tool.
Pros & Cons
- Pro: Accurate, free-floated barrel with standard nut for easy barrel swaps or maintenance.
- Pro: Lighter than a full MRAD—approximately 12.5 lbs—making it more portable for field use.
- Con: The fixed stock limits storage and transport options compared to folding-stock variants. Shooters who need a compact carry profile should consider the folding MRAD.

FAQ
Is the barrel user-swappable on the MRAD SMR?
Yes. The barrel is secured by a standard barrel nut, and the MRAD system is designed for tool-free barrel changes. You can swap to other MRAD barrels in compatible calibers, though the SMR is optimized for .300 Win Mag.
Does the fixed stock affect accuracy?
No. The fixed stock is rigid and eliminates the potential for play found in some folding mechanisms. It actually improves consistency for prone and bench shooting.
What scope mounts fit the MRAD SMR?
The receiver uses a 20 MOA Picatinny rail. Any standard 1913 rail mount will work. We recommend 34mm or 35mm rings for long-range scopes.
Can I use this rifle for hunting?
Yes, but its weight and length make it better suited for stationary or long-range hunting applications (e.g., mountain or prairie) rather than stalk hunting.
What is the barrel twist rate?
Per Barrett specs, the .300 Win Mag barrel has a 1:10 twist rate, optimized for bullets between 178 and 220 grains.
