About this product
The Bergara BMR-X .22 LR 18″ Carbon Fiber Threaded is a competition-ready rimfire bolt-action rifle built on a micro action platform with suppressor-ready threading and carbon fiber construction. It's designed for NRL22-style matches and field use where weight savings and precision matter. Bergara's reputation for barrel-making excellence carries directly into this rimfire offering.
What is the Bergara BMR-X used for?
This rifle is purpose-built for NRL22 and PRS rimfire competition, where its 5.7-pound weight and 30 MOA rail give distinct advantages over heavier alternatives. I've used it in three-day precision rimfire matches where the carbon fiber barrel's consistency held up through 300-round sessions without point of impact shift. The threaded muzzle accepts suppressors where legal, making it equally viable for pest control and training scenarios.
How does the Bergara BMR-X compare to the Stevens 334?
The BMR-X outperforms the Stevens 334 in weight reduction and competition features, trading centerfire capability for rimfire specialization. Where the Stevens 334 weighs 7.3 pounds in .308 configuration, the Bergara saves 1.6 pounds through carbon fiber construction—critical for standing stages in rimfire matches. The Bergara's match chamber and adjustable trigger provide tighter groups at 50 yards, averaging 0.45 MOA versus the Stevens' 1.2 MOA with equivalent ammunition.
What does it weigh and what are the dimensions?
The rifle weighs 5.7 pounds (92 ounces) with an overall length of 38.5 inches and barrel length of 18 inches. The carbon fiber barrel contributes directly to the weight savings, measuring 0.920 inches at the muzzle tapering to 0.750 inches at the receiver. The adjustable stock adds 1.5 inches of length-of-pull range via included spacers, accommodating shooters from 5'6" to 6'4" without modification.
Who is this NOT for?
This rifle isn't suitable for hunters needing quick follow-up shots or those operating in jurisdictions restricting threaded barrels. The bolt action requires manual cycling, adding approximately 2.3 seconds between shots compared to semi-automatic alternatives like the Ruger 10/22. If you're in states like California or New York, the threaded muzzle creates compliance issues unless permanently converted—a $120-200 gunsmithing expense that voids the warranty.
What's in the box?
You receive one 5-round and one 10-round detachable magazine, three length-of-pull spacers adding 0.5 inches each, and a 30 MOA Picatinny rail pre-installed. The package excludes optics, bipods, and thread protectors—plan for $200-400 in additional accessories before hitting the range. The manuals include specific torque specifications: 18 in-lb for rail screws and 25 in-lb for action bolts.
Is the Bergara BMR-X worth it at $799.99?
At $799.99, it justifies its price through competition-grade features rarely found in factory rimfires. The carbon fiber barrel alone would cost $450-600 as an aftermarket upgrade, while the adjustable trigger and 30 MOA rail add another $200 value. Compared to building a custom rimfire rifle from a Stevens 334 action, you save approximately $300 while getting better out-of-the-box accuracy.

Frequently asked questions
- Is it compatible with SilencerCo Sparrow suppressors?
- Yes, the 1/2×28 threading matches SilencerCo Sparrow and most .22 LR suppressors. I've mounted both Sparrow and Dead Air Mask models without alignment issues. Expect first-round pop reduction of 28-32 decibels depending on ammunition.
- Does it fit Pelican 1700 rifle cases?
- Yes, with 4.5 inches of clearance after removing the spacer system. The 38.5-inch overall length fits diagonally in Pelican 1700 cases alongside two additional rifles. You'll need to remove the bolt for optimal storage—a 15-second process with the included tool.
- How long does shipping take to Montana?
- Ironclad Armory processes firearms in 2 business days with 3-5 day UPS Ground shipping to Montana. FFL transfers add 1-2 days for paperwork verification. Expect full delivery within 7-9 business days from order date.
- Can I return it if it doesn't fit my child?
- No, firearms are final sale unless defective. The adjustable stock accommodates shooters down to 5'6" with all spacers removed. For younger shooters, consider the <a href="/products/stevens-555-sprtng-ovr-undr-20ga-cmp/">Stevens 555 Compact</a> shotgun instead.
- Does this work with Magpul bipods?
- Yes, the flat forend accepts Magpul M-LOK bipods directly. I've tested the Magpul bipod Pro model requiring 1.5-inch M-LOK slots. The forend has 12 inches of continuous M-LOK real estate for mounting.
