Bergara BMR-X .22 WMR 18in Steel Threaded Barrel Rifle

The Bergara BMR-X .22 WMR 18in Steel Threaded Barrel Rifle is a rimfire bolt-action platform built for precision shooters who demand repeatable accuracy from a lightweight, adjustable package. Chambered in .22 Winchester Magnum, this rifle uses Bergara’s Micro Rimfire action and a heavy-profile 18-inch steel barrel with a threaded muzzle, giving you the stiffness and consistency needed for tight groups at extended rimfire distances. The synthetic stock offers length-of-pull adjustment, and the externally adjustable trigger lets you dial in pull weight without tools. An integral 30 MOA Picatinny rail comes standard, so you can mount high-magnification optics without shimming. This is a production rifle that punches above its price point for competitive rimfire shooting or precision small-game hunting.

Key Features

• Heavy-Profile 18-Inch Steel Barrel — WHY IT MATTERS: The added mass dampens barrel harmonics, keeping vertical stringing under 0.5 MOA with quality match ammunition, while the 18-inch length balances portability with velocity retention for .22 WMR.
• Externally Adjustable Performance Trigger — WHY IT MATTERS: You can adjust pull weight from 1.5 to 3.5 pounds using a simple hex key, eliminating creep and overtravel for consistent break at the bench or in NRL22 stages.
• Integral 30 MOA Picatinny Rail — WHY IT MATTERS: The built-in cant gives you enough elevation travel to dial out to 200+ yards with most rimfire scopes, so you don’t have to buy a separate base or shim the rings.
• Adjustable Length-of-Pull Stock — WHY IT MATTERS: The synthetic stock includes spacers to change LOP from 12.5 to 14 inches, letting you fit the rifle to your body for consistent cheek weld and recoil management.
• Threaded Muzzle (1/2×28 TPI) — WHY IT MATTERS: You can attach a suppressor or muzzle brake directly without an adapter, keeping the overall length short for suppressed rimfire shooting.

Who It’s For

This rifle is designed for the rimfire competitor who wants a dedicated .22 WMR platform for NRL22-X, PRS Rimfire, or similar matches where velocity and wind-bucking matter. It also appeals to small-game hunters who need a lightweight, accurate rifle for coyotes, rabbits, or squirrels at ranges beyond 100 yards. The adjustable stock and trigger make it ideal for shooters who share a rifle with family members or teammates, since you can tailor fit and feel without tools.

Pros & Cons

• Pro: The 30 MOA rail is a factory-installed upgrade that saves you $50–$80 on aftermarket bases.
• Pro: The trigger is crisp and user-adjustable, competing with aftermarket units from Timney or TriggerTech in this price range.
• Con: The synthetic stock, while functional, lacks the rigidity of a chassis system — you may want to bed the action for maximum consistency in long-range matches.

According to NSSF data, .22 WMR rimfire rifles account for roughly 8% of the rimfire market, but the BMR-X’s adjustable features and 30 MOA rail make it a standout for precision shooters who want more velocity than .22 LR offers.
