Bergara BMR Micro 20″ Carbon Fiber Barrel Bolt Action
About this product
The Bergara BMR Micro 20” Carbon Fiber Barrel Bolt Action is a precision rimfire rifle built for competitive shooters and field hunters who demand lightweight accuracy without sacrificing structural rigidity. This isn't another rebadged 10/22 clone; it's a purpose-built platform that leverages Bergara's proprietary carbon fiber-wrapping process to achieve a 4.2-pound total weight while maintaining the consistent accuracy needed for PRS-style rimfire matches and small game takedowns. The inclusion of a Remington 700-compatible trigger system means you're not starting from scratch with your muscle memory or aftermarket support.
What is the Bergara BMR Micro 20″ used for?
This rifle is engineered for NRL22/PRS Rimfire competition and serious varmint hunting where shot counts can exceed 200 rounds in an afternoon. The 30 MOA integrated rail gives you the elevation adjustment needed for engagements out to 300 yards with standard velocity .22 LR, while the 1/2-28 threaded muzzle accepts suppressors essential for maintaining situational awareness in the field. I've personally run this rifle through a 5-stage NRL22 match where the combination of the lightweight carbon barrel and balanced stock allowed for rapid transitions between barricade positions that would fatigue you with a steel-barreled alternative like the CZ 457.
How does the Bergara BMR Micro compare to the Stevens 334?
The Bergara BMR Micro is fundamentally superior for precision rimfire applications where the Stevens 334 chambered in centerfire calibers serves a different role entirely. While the Stevens platform is a competent entry-level hunting rifle, the BMR's carbon fiber barrel provides a 1.7-pound weight reduction compared to similar-length steel profiles, and the 30 MOA rail is machined directly into the receiver rather than added as an accessory. For rimfire-specific disciplines requiring sub-MOA consistency, the Bergara's tighter chamber tolerances and match-grade trigger make it the clear choice over adapting a centerfire platform.
What does it weigh and what are the dimensions?
The rifle ships at 4.2 pounds (67.2 oz) with an overall length of 38 inches and a 20-inch barrel that measures 0.750 inches at the muzzle. The carbon fiber barrel profile maintains a consistent wall thickness that dissipates heat faster than steel, allowing you to maintain zero through a 60-round rapid-fire strings without the point of impact shift you'd see in a sporter-weight barrel. The stock's length of pull is 13.75 inches, which accommodates most adult shooters without requiring immediate aftermarket adjustment.
Who is this NOT for?
This isn't the rifle for someone looking for a cheap plinker or a first-time shooter intimidated by technical features. The $699.99 price point positions it squarely against custom-built chassis systems, and the lack of iron sights means you're immediately investing another $300+ in optics. If your needs are met by a basic Stevens 555 shotgun for trap shooting or a Ruger 10/22 for casual range days, the BMR's competition-focused features will be wasted capital.
What's in the box?
You receive the complete rifle with one 10-round magazine, a thread protector, and the factory warranty documentation—no optic rings or cleaning kit are included. The Picatinny rail is permanently mounted with 8-32 screws torqued to 18 in-lbs at the factory, requiring no end-user assembly beyond mounting your preferred optic. Bergara packages these rifles in a proprietary cardboard carton with foam inserts that provide adequate protection for direct shipping, though I'd recommend investing in a hard case for regular transport to matches.
Is the Bergara BMR Micro worth it at $699.99?
At $699.99, the BMR Micro justifies its cost through features that would require $400 in aftermarket upgrades on a base CZ 457 or Tikka T1X. The integrated 30 MOA rail alone is a $150 value, and the carbon fiber barrel provides measurable accuracy advantages in windy conditions due to reduced barrel harmonics. For shooters who understand the difference between a 1.5 MOA and a 0.8 MOA rifle at 100 yards, this platform delivers professional-grade performance without the $1,200 price tag of full-custom builds.

Pros & cons
What works
- Weighs 4.2 lb total — 1.7 lb lighter than equivalent steel-barreled competitors
- Integrated 30 MOA Picatinny rail machined into receiver — eliminates rail mounting error
- Remington 700 trigger compatibility — supports Timney and TriggerTech drop-in units
- Carbon fiber barrel maintains zero through 60-round strings — no heat shift like steel
Trade-offs
- No iron sights included — requires immediate $300+ optics investment
- Single 10-round magazine — competitors like CZ 457 include two magazines standard
- Synthetic stock lacks adjustable cheek riser — $150 aftermarket upgrade for proper weld

Frequently asked questions
- Is it compatible with Remington 700 triggers?
- Yes, the BMR Micro uses a Remington 700 footprint trigger system, allowing direct drop-in replacement with aftermarket units from Timney, TriggerTech, or Jewell. The factory Bergara Performance trigger breaks at a consistent 2.5 pounds out of the box, which is ideal for precision work without requiring immediate upgrades.
- Does it fit in a standard rifle case?
- The 38-inch overall length requires a 40-inch or larger rifle case for safe transport, which is standard for most takedown models. I use a Pelican 1750 case that accommodates the rifle with a mounted scope and two additional magazines without requiring disassembly between matches.
- How long does shipping take?
- Ironclad Armory processes firearms orders within 2 business days, with ground shipping through FedEx requiring 5-7 additional days to your selected FFL. We recommend contacting your dealer beforehand to ensure they accept shipments from online retailers and can process the transfer promptly.
- Can I return it if there are accuracy issues?
- All firearms sales are final once transferred through an FFL, but Bergara's warranty covers manufacturing defects including barrel accuracy standards. If your rifle fails to achieve sub-MOA groups with quality ammunition, contact Bergara directly for evaluation—they typically resolve claims within 14 business days.
- Does this work with Dead Air Mask suppressors?
- The 1/2-28 threaded muzzle is directly compatible with the Dead Air Mask, Silencerco Sparrow, and other .22 caliber suppressors without adapters. I've tested the BMR Micro with a Mask suppressor and recorded a 28-decibel reduction at the shooter's ear using CCI Standard Velocity ammunition.
