Key Features
- 18-inch Steel Threaded Barrel: The barrel’s 1:16 twist rate stabilizes standard and high-velocity .22 LR loads for sub-MOA accuracy at 50 yards. The threaded muzzle (1/2×28 TPI) accepts suppressors or compensators, reducing report and recoil for follow-up shots.
- Bergara Performance Trigger: A crisp, adjustable trigger breaks clean at 2.5 to 3.5 lbs out of the box. This eliminates creep and overtravel, letting you hold the crosshair on target without fighting the trigger.
- 30 MOA Picatinny Rail: The integrated rail provides a 30 MOA cant, giving you enough elevation adjustment for long-range rimfire shooting without maxing out your scope’s turrets. No need for aftermarket bases.
- Match Chamber: Bergara cuts the chamber to match-grade tolerances, ensuring consistent bullet seating and gas seal. This translates to tighter groups with bulk ammo and sub-0.5-inch groups with match rounds.
- Lightweight Synthetic Stock: The gray stock with black fleck weighs under 5 lbs total, making it easy to carry in the field for squirrel hunting or all-day matches. The stock has a raised comb for cheek weld with high-mounted optics.
Who It’s For
This rifle is built for serious rimfire shooters: law enforcement and military personnel running NRL22 or PRS Rimfire matches, hunters who need a lightweight .22 for small game, and competitors who demand accuracy without the bulk of a heavy target rifle. If you want a do-it-all rimfire that works for steel plates at 100 yards and headshots on rabbits at 50, this is your platform.
Pros / Cons
- Pros: Sub-MOA accuracy out of the box; adjustable trigger with clean break; 30 MOA rail eliminates need for aftermarket scope bases; threaded barrel for suppressor use; lightweight for field carry; uses standard 10-round rotary magazines.
- Cons: The stock is rigid polymer with no adjustable cheek riser, which can be a drawback for shooters with long necks or when using high-magnification scopes. You may need a cheek pad or aftermarket stock for a custom fit.

Note: The Geissele Super 700 is a centerfire rifle, not a direct rimfire competitor, but it represents the premium precision tier. The Timney 642 is a trigger-only option for rimfire builds. The Bergara BMR offers an integrated, ready-to-shoot package at a lower price point than those two combined.
