About this product
The Bergara BMR Micro Rimfire .22 WMR is a bolt-action rimfire rifle featuring a 20-inch carbon fiber barrel designed for precision shooting and field use. This model combines lightweight construction with match-grade accuracy, making it ideal for competitive rimfire events and small game hunting. Built on Bergara's proven micro-action platform, it delivers exceptional mechanical precision at an accessible price point.
What is the Bergara BMR Micro Rimfire used for?
This rifle is designed for NRL22-style competition and small game hunting where precision matters. The 20-inch carbon barrel maintains consistent velocities while the 30 MOA rail supports high-magnification optics for long-range rimfire shooting. I've found it particularly effective for prairie dog control at 150+ yards when paired with quality ammunition.
How does the Bergara BMR compare to the Stevens 334 Rifle?
The BMR outperforms the Stevens 334 in weight reduction and accuracy potential, weighing just 5.8 pounds compared to the Stevens' 7.3 pounds. While both use synthetic stocks, the BMR's carbon fiber barrel provides better thermal stability during sustained firing strings. The Stevens chambered in .308 Win offers more power for larger game but can't match the BMR's rimfire precision for target work.
What does it weigh and what are the dimensions?
The rifle weighs 5.8 pounds with an overall length of 38 inches. The 20-inch barrel features a 1:16 twist rate optimized for .22 WMR ammunition, while the 30 MOA integral rail provides ample elevation adjustment for competition optics. The synthetic stock measures 13.5 inches length of pull, accommodating most adult shooters without modification.
Who is this NOT for?
This rifle isn't suitable for high-volume plinkers seeking semi-auto functionality. The bolt-action design limits practical rate of fire to about 15 rounds per minute compared to semi-autos' 30+. It's also not ideal for suppressors despite the threaded muzzle - .22 WMR produces supersonic cracks that defeat most sound reduction efforts unless using specialty subsonic loads.
What's in the box?
You receive the complete rifle with thread protector installed, one 5-round magazine, and owner's manual. Unlike some competitors, Bergara doesn't include optic mounts or cleaning kits - budget $150+ for a quality rimfire scope and rings. The integral 30 MOA rail accepts standard Picatinny mounts, but you'll need to source them separately.
Is the Bergara BMR worth it at $699.99?
At $699.99, it represents solid value for serious rimfire competitors but overkill for casual shooters. The carbon barrel alone would cost $400+ aftermarket, making this a solid package deal compared to custom builds. For hunters needing versatile performance, consider whether the Stevens 555 Sporting Compact might better serve dual-purpose roles.

Frequently asked questions
- Is it compatible with standard .22 LR ammo?
- No, this rifle is chambered exclusively for .22 Winchester Magnum Rimfire (.22 WMR) cartridges. Attempting to fire .22 LR could cause dangerous pressure issues and accuracy problems. Always verify caliber marking before loading - the chamber is specifically cut for the longer .22 WMR case.
- Does it fit youth or smaller shooters?
- The 13.5 inch length of pull accommodates most adults but may be long for shooters under 5'6". Stock modifications would require gunsmithing - for younger shooters, consider the compact version of the <a href="/products/stevens-555-sprtng-ovr-undr-20ga-cmp/">Stevens 555</a> shotgun instead.
- How long does shipping take to Montana?
- FFL transfers to Montana typically take 3-5 business days after processing. All firearms ship via UPS or FedEx with adult signature required - allow 2 additional days for rural locations like Bozeman. We recommend contacting your local FFL before ordering to confirm transfer fees.
- Can I return it if there are accuracy issues?
- Returns require inspection by our gunsmiths within 30 days - mechanical defects are covered but ammunition-related accuracy problems aren't. Bergara guarantees 1 MOA accuracy with match-grade ammo; if your groups exceed 1.5 inches at 50 yards with quality ammunition, contact us for troubleshooting.
