If you’re grinding through stages at a PRS rimfire match or stacking dimes on steel, the Bergara BMR-X .22 LR 18in Steel Barrel 5/10-Rd is the tool that closes the gap between rimfire and centerfire precision. This isn’t a plinker with a paint job—it’s a competition chassis rifle built around Bergara’s Micro Rimfire action and a heavy-contour 18-inch steel barrel. It ships with both a 5-round and a 10-round detachable magazine, so you can adapt between NRL22 stages and practice sessions without swapping gear. The synthetic stock borrows ergonomics from the BXR line, giving you an adjustable comb and length of pull that locks in your natural point of aim. If you’re serious about rimfire accuracy, this is the platform.

Key Features
- Heavy-Contour 18-Inch Steel Barrel – WHY IT MATTERS: The extra mass soaks up heat and maintains harmonics through a 10-round string, so your zero stays consistent from shot one to shot ten.
- Micro Rimfire Bolt Action – WHY IT MATTERS: Bergara’s dedicated rimfire bolt design reduces lock time and provides a crisp 60-degree bolt throw, letting you cycle fast without disturbing your sight picture.
- Adjustable BXR-Inspired Stock – WHY IT MATTERS: Comb height and length of pull adjust without tools, so you can dial in cheek weld for prone, barricade, or offhand positions—critical for repeatable holds.
- Dual Magazine Capacity (5 & 10 Rounds) – WHY IT MATTERS: Use the 5-rounder for practice or the 10-rounder for match stages; both drop free and seat positively, saving you seconds on reloads.
- Detachable Box Magazine System – WHY IT MATTERS: Reloads are faster than a fixed tube, and the mag release is ambidextrous, so left- and right-handed shooters run it the same way.
Who It’s For
This rifle is for the competitor who treats .22 LR like a discipline, not a budget afterthought. If you shoot NRL22, ARA, or steel challenge, the BMR-X gives you the ergonomics and accuracy to run stages without fighting the gun. It’s also a fit for the precision enthusiast who wants a trainer that mimics a centerfire chassis rifle—same stock adjustments, same trigger feel, same manual of arms.
Pros & Cons
- Pros: Accurate heavy barrel, adjustable stock, dual mags included, smooth Micro Rimfire action, good weight balance for positional shooting.
- Cons: The trigger is serviceable but not match-grade out of the box—most competitors will swap it for a Timney or trigger job. Stock texture could be grippier in wet conditions.
Comparison: Bergara BMR-X vs. Ruger Precision Rimfire vs. CZ 457 Varmint
| Feature | Bergara BMR-X | Ruger Precision Rimfire | CZ 457 Varmint |
|---|---|---|---|
| Barrel Length | 18 in, steel, heavy contour | 18 in, steel, heavy taper | 20.5 in, steel, varmint contour |
| Stock Type | Adjustable synthetic (BXR-based) | Adjustable synthetic (AR-style grip) | Fixed synthetic or wood |
| Magazine Capacity | 5 & 10 rounds (included) | 10 & 15 rounds (aftermarket) | 5 rounds (10 optional) |
| Bolt Throw | 60 degrees | 60 degrees | 60 degrees |
| Weight | 6.9 lbs | 7.0 lbs | 7.3 lbs |
| Price | $699.99 | $479.99 | $599.99 |
| Best For | PRS/NRL22 competition out of the box | Budget competition with AR-style grip | Hunting/benchrest with wood stock |
The Ruger Precision Rimfire is cheaper but lacks the stock adjustability and barrel contour of the Bergara. The CZ 457 Varmint is a tack driver but has a fixed stock and limited mag capacity out of the box. The BMR-X splits the difference with competition-ready ergonomics and accuracy at a price that doesn’t require a second mortgage.
FAQ
What is the barrel twist rate on the Bergara BMR-X .22 LR?
The barrel has a 1:16 twist rate, optimized for standard and high-velocity .22 LR ammunition up to 40 grains. It stabilizes most match loads well.
Does the Bergara BMR-X come with scope bases or rings?
No, it ships with a Picatinny rail pre-installed on the receiver, so you can mount your own scope rings. No bases needed.
Is the stock adjustable for length of pull and comb height?
Yes, both are tool-less adjustable. The comb height adjusts via a knob, and the length of pull uses spacers (included).
Can I use the 10-round magazine in a .22 LR competition?
Yes, the 10-round magazine is legal in most rimfire matches, including NRL22, unless the stage specifies a capacity limit. Check your match rules.
Does the Bergara BMR-X accept aftermarket triggers?
Yes, it uses a standard Remington 700-style trigger footprint, so drop-in triggers from Timney, Geissele, and others work with minor fitting.
