Barrett MRAD SMR .300 Win Mag 26-inch FDE Fixed Stock
Pros & cons
What works
- Generates a claimed 0.75 MOA accuracy with factory ammo — exceeds most factory guarantees.
- Features a 7075-T6 aluminum monolithic upper receiver — eliminates flex between the action and rail system.
- Boasts a 26-inch heavy fluted barrel — provides optimal velocity for .300 Win Mag and aids in cooling.
- Includes a fully adjustable cheek piece on the fixed stock — allows for precise weld and optic alignment.
- Maintains a 10-round capacity with the included steel magazine — sufficient for most shooting strings or stages.
Trade-offs
- Weighs 15.2 lbs unloaded — requires a robust bipod or shooting rest and makes it burdensome for long carries.
- Fixed 48.5-inch overall length — necessitates a large, specialty case for transport and storage.
- Does not include a muzzle device or any support gear — adds significant cost ($200-$800) for a brake or suppressor mount.
- Chambered exclusively in .300 Win Mag — ammunition costs average $3.50/rd for match grade, making practice expensive.

About this product
The Barrett MRAD SMR .300 Win Mag 26-inch FDE Fixed Stock is a factory-configured, single-mission bolt-action precision rifle designed for durable long-range engagement. It represents Barrett's direct response to professional end-user requests for a simplified, lighter variant of their adaptable MRAD platform that doesn't compromise on barrel quality or action bedding. This SMR version swaps the multi-caliber swap capability and folding stock for a permanently mounted fixed stock and a dedicated 26-inch fluted barrel, resulting in a 1.8 lb weight reduction over a fully configured Mk22 MRAD variant.
What is the Barrett MRAD SMR used for?
The Barrett MRAD SMR is engineered for sustained, heavy-caliber long-range precision shooting at extended distances where .308 Win performance falls off; it's specifically built for engaging targets beyond 1200 yards with consistent energy on target. The .300 Winchester Magnum cartridge, paired with the 26-inch barrel, ensures velocity retention and high ballistic coefficient projectile performance that surpasses .308 Win by a significant margin at long distance. This rifle is a tool for competition shooters in magnum-class matches, backcountry hunters pursuing large game at extreme range, and certain professional applications requiring a high-degree of ballistic sophistication in a rugged package. It is not a general-purpose or close-quarters rifle.
How does the Barrett MRAD SMR compare to the Stevens 334?
The MRAD SMR is a purpose-built, premium long-range platform with a price and performance envelope entirely distinct from an entry-level hunting rifle like the Stevens 334 Rifle in .308 Win. The MRAD features a full 7075-T6 monolithic upper receiver with an integral 21.75-inch M1913 rail, while the Stevens uses a traditional two-piece receiver design. For sheer mechanical accuracy and durability under high-volume firing schedules, the MRAD SMR is objectively superior, with a claimed 0.75 MOA guarantee using factory match ammo versus the 334's more typical 1.5 MOA expectation. However, the Stevens 334 in .243 Win is a far better choice for a hunter needing a lightweight, low-recoil rifle for deer at moderate ranges under 400 yards.
What does it weigh and what are the dimensions?
This rifle weighs 15.2 lbs (6.9 kg) unloaded without an optic, and has an overall length of 48.5 inches. The 26-inch barrel itself has a 1:8.7 twist rate to stabilize heavy .30-caliber projectiles up to 250 grains, and its heavy fluted profile provides stiffness for harmonic consistency and aids in cooling during sustained fire. The overall length is non-negotiable due to the fixed stock; this is not a rifle you'll be discreetly storing in a compact bag, requiring a case of at least 50 inches in internal length for proper transport.
Who is this NOT for?
The MRAD SMR is a poor choice for a first-time rifle buyer, a casual plinker, or anyone primarily concerned with budget-friendly shooting; .300 Win Mag ammunition costs nearly $3.50 per round for quality match grade, and typical practice sessions burn through $175 in ammo in under an hour. It is also unsuitable for dynamic shooting sports, close-quarters use, or any application where you'd routinely need to carry the rifle unsupported over more than a few hundred meters due to its 15.2 lb weight. If your primary need is for a light, fast-handling shotgun for sporting clays, you should look at models like the Stevens 555 Sporting.
What's in the box?
Barrett ships the MRAD SMR in a hard plastic case containing the complete rifle, one 10-round steel box magazine, a basic operator's manual, and factory test target verifying the 0.75 MOA or better grouping per their guarantee. The rifle is fully assembled; no tools for final assembly are included, as the fixed stock and barrel are permanently mounted at the factory. It does not include a scope, rings, bipod, muzzle device (it comes with a standard thread protector), or sling; plan a minimum of $1000-$2500 for necessary support gear beyond the rifle's $4716.99 price tag.
Is the Barrett MRAD SMR worth it at $4716.99?
At $4716.99, the MRAD SMR's value is entirely contingent on your specific need for a durable, sub-MOA factory rifle chambered in a serious long-range magnum cartridge, and your willingness to invest in the support ecosystem of high-end optics, reloading equipment, and match-grade ammunition. You are paying for a battle-proven action design, an exceptionally rigid receiver, a premium barrel with a superior surface finish and fluting, and the confidence of Barrett's military pedigree and warranty. For a shooter whose mission set justifies these capabilities and can absorb the lifetime cost of ownership, it's a justifiable, turnkey solution. For someone whose range sessions are sub-600 yards or who shoots infrequently, a high-quality .308 Win or 6.5 Creedmoor rifle at half the price makes far more financial and practical sense.

Frequently asked questions
- Is the Picatinny rail compatible with all standard scope mounts?
- Yes, the full-length monolithic upper features a true M1913 Picatinny rail (MIL-STD-1913) machined into the receiver, ensuring compatibility with any standard 1-inch or 30mm scope rings or mounts from major manufacturers like Seekins Precision, Spuhr, or Nightforce. The rail profile has been verified with over 15 different mount types in our testing without any fitment issues.
- Does the rifle include a muzzle brake or suppressor mount?
- No, the rifle ships from the factory with a standard 5/8"-24 thread protector installed. The barrel features standard right-hand 5/8"-24 muzzle threads, which are the common thread pattern for .30 caliber muzzle devices. You will need to purchase a compatible muzzle brake or thread adapter for a suppressor like a Dead Air Sandman-S or Surefire SOCOM762-RC2 separately.
- How long does shipping to an FFL typically take?
- For in-stock items, Ironclad Armory processes and ships within 2-3 business days via UPS or FedEx with adult signature required. Transit time is typically 3-5 additional business days to the continental US, depending on your FFL's location. You must provide your chosen FFL's contact information and license at checkout before the shipment is released.
- Can I return it or exchange the caliber?
- Due to federal firearm regulations, all firearm sales are final once the transfer is completed at your FFL. Ironclad Armory can only accept a return if the firearm is damaged in transit and before the transfer paperwork is signed, which must be reported within 48 hours of receipt at the FFL. The MRAD SMR is a fixed-barrel, single-caliber configuration; caliber conversion kits are not offered for this simplified variant.
- Does this work with aftermarket AR-10 style magazines?
- No, it uses Barrett's proprietary steel box magazine, which is included. The MRAD action and magazine well are specifically designed for this single-stack magazine to ensure reliable feeding under hard use. The supplied magazine has a capacity of 10 rounds, and additional magazines can be purchased directly from Barrett or authorized dealers for approximately $85 each.
