Barrett MRAD SMR .300 Win Mag 26-inch Fixed Stock
Pros & cons
What works
- 26-inch match-grade, fluted barrel with 1:9.5 twist maximizes .300 Win Mag ballistics for 1,000+ yard stability.
- User-adjustable match trigger tunes from 1.5 to 4.5 pounds with a simple hex key for personalized break.
- Fixed stock with adjustable comb (13.5-15.5" LOP) provides a solid, repeatable cheek weld for shot-to-shot consistency.
- 21.75-inch continuous M-LOK handguard rail offers extensive accessory mounting for bipods, night vision, and levels.
Trade-offs
- 13.5-pound unloaded weight and 46.75-inch length make it cumbersome for hunting or off-hand shooting.
- Fixed, non-folding stock design limits transport options compared to the standard MRAD, a $500+ value lost.
- No muzzle device included; you must purchase and time a muzzle brake or suppressor mount separately.
- Single-caliber configuration locks you into .300 Win Mag; caliber swaps require a complete new barrel/bolt assembly.

About this product
The Ironclad Armory Barrett MRAD SMR .300 Win Mag 26-inch Fixed Stock is a dedicated single-caliber precision bolt-action rifle built for consistent, repeatable long-range performance. It focuses the Barrett MRAD platform into a streamlined configuration, retaining the core mechanical accuracy while eliminating the multi-caliber adapters and associated weight. This is not a beginner's plinker; it's a tool for disciplined shooters who understand velocity nodes and ballistic coefficients.
What is the Ironclad Armory MRAD SMR used for?
This rifle is explicitly designed for long-range precision target shooting and tactical competitions where wind calls matter at distances beyond 800 yards. The 26-inch barrel maximizes .300 Winchester Magnum powder burn, stabilizing heavy ~220-grain projectiles for superior ballistic performance compared to shorter barrels. It's built for a single firing line, not hunting or dynamic movement, with a fixed stock and 13.5-pound weight demanding a solid rest or bipod.
How does the Ironclad Armory MRAD SMR compare to the Stevens 334 Rifle chambered in .308 Win?
The MRAD SMR offers superior long-range ballistic performance and mechanical precision at nearly four times the price of the Stevens 334 Rifle in .308 Win. The Stevens 334 uses a budget-friendly push-feed action and a 20-inch barrel, making it a capable 600-yard rifle for general-purpose use at roughly 7.5 pounds. The MRAD SMR’s controlled-round-feed action, true match-grade barrel, and robust chassis system are for shooters chasing consistent sub-MOA groups at 1,000+ yards, where the .300 WM's retained energy and flat trajectory are decisive. The Stevens 334 is better for a first bolt-action rifle; the MRAD SMR is better for national-level competition.
What does it weigh and what are the dimensions?
Unloaded and without optics, the rifle weighs 13.5 pounds and measures 46.75 inches in overall length. The 26-inch barrel has a 1:9.5 twist rate, optimal for stabilizing the long, heavy match projectiles this cartridge is designed for. The handguard’s 21.75-inch continuous top rail provides ample real estate for night vision bridge mounts or a rear-mounted bubble level, while the fixed stock’s length of pull is adjustable from 13.5 to 15.5 inches.
Who is this NOT for?
This rifle is not for a new shooter, a budget-conscious hunter, or anyone needing a lightweight, portable firearm. The $4,700 price tag represents an investment in mechanical precision that a novice cannot exploit. The fixed, non-folding stock configuration also makes this a poor choice for shooters operating from confined vehicles or requiring a compact transport solution, unlike some multi-caliber MRAD variants. If your primary use is a deer stand at 300 yards, you are better served by a lighter, less expensive platform like the Stevens 334 series.
What's in the box?
The rifle ships with one 5-round steel AICS-pattern magazine, a basic set of Allen wrenches for the user-adjustable 1.5 to 4.5-pound trigger and comb height, and a limited-lifetime warranty registration card. It does not include a scope, rings, bipod, muzzle device, or a case. You will need to budget an additional $1,000-$3,000 for a suitable optic and mount to realize this rifle’s potential.
Is the Ironclad Armory MRAD SMR worth it at $4,716.99?
At this price, it is worth it only for the serious precision rifle competitor or specialist who requires the absolute consistency and ballistic advantage of a dedicated .300 Win Mag platform. You are paying for the Barrett name, the proven MRAD action, and a barrel that is hand-fitted and verified at the factory. For a shooter needing a single, ultra-reliable 1,000+ yard rifle and who values the SMR’s reduced complexity over the multi-caliber MRAD, it is a justified expense. For anyone else, a more versatile or affordable rifle will be a smarter purchase.

Frequently asked questions
- Is it compatible with AICS-pattern magazines?
- Yes. The MRAD SMR utilizes a standardized Accuracy International Chassis System (AICS) short-action magazine well. It reliably feeds from all quality steel or polymer AICS-pattern magazines in .300 Winchester Magnum, such as those from Accuracy International, Magpul, or Accurate-Mag. The rifle ships with one 5-round steel magazine.
- Does this work with a standard .30 caliber suppressor?
- It can, but requires attention to detail. The barrel features a standard 5/8x24 threaded muzzle, compatible with most .30 cal rifle suppressors. However, the .300 Win Magnum generates significant gas volume; you must verify your suppressor is explicitly rated for the cartridge. I recommend a high-baffle-count, full-auto-rated model from a reputable manufacturer like SilencerCo or Dead Air to handle the pressure and heat.
- Can the fixed stock be replaced with a folding stock?
- No, not without significant gunsmithing and possibly violating the rifle's warranty. The SMR (Single Mission Rifle) variant uses a proprietary fixed-stock receiver extension. Converting it to accept a folding mechanism like the standard multi-caliber MRAD would require sourcing and fitting the correct rear trunnion assembly, a job best left to a qualified Barrett-certified armorer. If you need a folding stock, purchase the standard MRAD model from the outset.
- How long does shipping take?
- Orders from Ironclad Armory typically ship within 3-5 business days after the mandatory 4473 background check is approved by your selected FFL dealer. Transit time via our contracted carriers is usually 2-4 business days for the continental US. The entire process from order to your FFL rarely exceeds 10 business days, barring state-specific waiting periods.
