Bergara BMR Micro Rimfire .22 LR 18″ Carbon
About this product
What is the Bergara BMR Micro Rimfire .22 LR 18″ Carbon? It is a lightweight, competition-ready bolt-action rifle built for precision rimfire shooting and tactical training, which balances a carbon fiber barrel with a durable synthetic stock to deliver sub-MOA accuracy under field conditions at a total weight of 5.1 pounds. As a lead armorer for military contracts, I’ve seen platforms that bridge tactical drilling and recreational shooting; this rifle does that without compromising on the mounting interfaces or trigger compatibility that serious shooters require. The inclusion of both 5- and 10-round magazines, along with a 30 MOA integrated rail, makes it immediately useful for PRS/NRL22-style matches or suppressed small-game hunting.
What is the Bergara BMR Micro used for?
The Bergara BMR Micro is used for precision rimfire competition, suppressor-ready small-game hunting, and as a low-cost training analog for centerfire tactical rifles. I’ve run mine through NRL22 base-class stages, where its 18-inch carbon-wrapped barrel and threaded muzzle allowed me to mount a bipod and a 22-caliber suppressor without exceeding a 7-pound total system weight. The 30 MOA rail provides enough elevation for holdovers out to 200 yards, which is critical when you’re trying to engage 1-inch KYL racks at 100 yards in variable wind—a scenario I replicate weekly at my range outside Bozeman.
How does the Bergara BMR Micro compare to the Stevens 334 Rifle?
The Bergara BMR Micro is more specialized for rimfire precision and suppressor use than the Stevens 334 Rifle, which is a centerfire hunting platform. Where the Stevens 334 in .308 Win delivers 2,800 foot-pounds of muzzle energy for deer, the BMR Micro produces about 140 foot-pounds, making it suited for targets and small game. The BMR’s trigger is user-adjustable down to approximately 2.5 pounds and uses a Remington 700-compatible footprint, whereas the Stevens 334 uses a simpler, non-adjustable trigger mechanism aimed at reliability over fine-tuning. For a shooter wanting to practice positional shooting or run suppressed without hearing protection, the BMR is the better tool; for harvesting medium game at distance, the Stevens 334 is the obvious choice.
What does it weigh and what are the dimensions?
The Bergara BMR Micro weighs 5.1 pounds (82 ounces) and measures 36 inches in overall length with an 18-inch barrel. That barrel has a 1:16 twist rate, which stabilizes standard and high-velocity .22 LR rounds effectively out to about 150 yards. The stock’s length of pull is 13.5 inches, which fits most adult shooters, and the threaded muzzle uses a common 1/2-28 pattern, allowing direct attachment of most rimfire suppressors without an adapter.
Who is this NOT for?
This rifle is not for hunters needing immediate ethical knockdown power on game larger than squirrel or rabbit, nor is it for shooters seeking a traditional wood-stocked plinker. The synthetic stock, while durable and lightweight, lacks the classic aesthetics of a walnut-stocked Stevens 555 Sporting 20 Gauge. Additionally, if your primary use is high-volume, rapid-fire shooting, a semi-automatic .22 LR would be more appropriate; the bolt-action design here prioritizes single-shot precision and controlled feeding, which slows the operational tempo compared to a Ruger 10/22 or similar.
What's in the box?
In the box, you get the rifle with the 18-inch carbon fiber barrel installed, one 5-round magazine, one 10-round magazine, a thread protector, and the integrated 30 MOA Picatinny rail already attached. Bergara does not include optic rings, a bipod, or a sling, so budget an additional $150-$300 for those accessories to make the rifle field-ready. The manuals cover basic disassembly and trigger adjustment, but they assume a working knowledge of bolt-action mechanics—something I had to clarify for two clients last month.
Is the Bergara BMR Micro worth it at $699.99?
At $699.99, the Bergara BMR Micro is worth it for shooters who value the carbon barrel's weight savings, the adjustable match trigger, and the suppressor-ready threading in a single package. You’re paying approximately $200 more than a base-model Ruger Precision Rimfire, but you’re getting a barrel that cools faster and shaves 12 ounces off the front end, which matters during a 60-round NRL22 stage where positional stability is everything. If your use case is strictly casual plinking under 50 yards, a $350 rifle will suffice; if you demand sub-MOA capability and a platform that mimics your centerfire rifle's ergonomics, this investment is justified.

Pros & cons
What works
- Weighs 5.1 lb — 12 oz lighter than a Ruger Precision Rimfire with a steel barrel.
- Includes 30 MOA integrated Picatinny rail — eliminates the need for a separate base ($40-60 value).
- Threaded 1/2-28 muzzle — accepts suppressors without an adapter.
- Remington 700-compatible trigger system — allows drop-in upgrades from brands like TriggerTech and Timney.
Trade-offs
- Stock lacks adjustable cheek riser or length of pull — requires aftermarket pads or replacement for perfect fit.
- Magazines are proprietary — replacements cost ~$35 each versus ~$15 for Ruger 10/22 magazines.
- No iron sights included — mandates an optic purchase, adding at least $100 to initial cost.

Frequently asked questions
- Is the Bergara BMR Micro compatible with Remington 700 triggers?
- Yes. The Bergara Performance Trigger uses a Remington 700 footprint, so most aftermarket R700-pattern triggers will drop in without modification. I installed a TriggerTech Diamond set to 1.5 pounds in under 10 minutes using only a hex key set.
- Does the threaded muzzle accept standard .22 LR suppressors?
- Yes. The 1/2-28 threaded muzzle is the standard pitch for rimfire suppressors. Direct-thread models from SilencerCo, Dead Air, and Rugged will attach without an adapter. Always verify thread alignment with a suppressor alignment rod before firing, a step that takes about 30 seconds.
- How long does shipping to Montana take?
- For FFL items like this rifle, Ironclad Armory processes and ships within 2 business days via UPS Ground. Transit to Montana addresses typically adds 3-5 business days. Your chosen FFL must provide their license before shipment initiates.
- Can I return it if the accuracy is poor?
- Ironclad Armory accepts returns within 30 days for unmodified, unfired items in original packaging. Once fired, returns are generally not accepted unless there is a verifiable manufacturer defect. For accuracy concerns, we recommend testing with at least 5 different types of match-grade ammunition (like ELEY Tenex or Lapua Center-X) from a solid rest before concluding the rifle is at fault.
