Hammerli Arms Force B1 Combo Rifle 22lr / 22 Mag AllWeather Black Limited Edition

The Hammerli Arms Force B1 Combo Rifle 22lr / 22 Mag AllWeather Black Limited Edition is a straight-pull rimfire platform built for shooters who need one rifle to handle two calibers without compromise. With a quick-change barrel system, you swap between .22 LR and .22 WMR in under a minute — no tools, no gunsmith. The AllWeather black synthetic stock and 16.1-inch threaded barrel (1/2×28) make this a go-to for training, small game, and precision plinking in rain, snow, or mud.

Key Features

• Straight-pull bolt action — Faster follow-up shots than a traditional bolt gun, and nearly silent cycling. Why it matters: you stay on target without breaking cheek weld, critical for timed drills or hunting where noise spooks game.
• Quick-change barrel system — Switch between .22 LR and .22 WMR in seconds with two included barrels. Why it matters: one rifle covers plinking, training, and varmint hunting without buying a second gun.
• 16.1-inch threaded barrel (1/2×28) — Ready for suppressors or muzzle brakes. Why it matters: keeps the rifle compact while letting you run a can for hearing-safe training or reduced recoil.
• Integral Picatinny rail — Direct-mount optics without additional bases. Why it matters: zero shift is minimized, and you can run LPVOs, red dots, or thermal sights with confidence.
• AllWeather synthetic stock — Resists moisture, temperature swings, and rough handling. Why it matters: the rifle stays accurate when you’re hunting in a downpour or shooting in sub-zero temps.

Who It’s For

This combo is for the shooter who wants one rimfire platform that does double duty. If you run a precision rifle in centerfire, the Force B1 is a perfect trainer — same manual of arms, lower cost per round. Small game hunters will appreciate the ability to swap from .22 LR for squirrels to .22 WMR for coyotes. It’s also ideal for rimfire competition shooters who need a fast, reliable bolt gun that can handle both calibers on the same match day.

Pros & Cons

• Pro: Two calibers in one rifle, saves money and safe space.
• Pro: Straight-pull action is faster than traditional bolts and quieter than semi-autos.
• Pro: Threaded barrel and Picatinny rail are ready out of the box.
• Con: The synthetic stock feels utilitarian — you won’t mistake it for a custom chassis. It’s functional, not fancy.
• Con: Limited aftermarket support for triggers and stocks compared to popular platforms like the 10/22.

FAQ

How long does it take to swap barrels on the Force B1?

Under one minute. Loosen two screws, slide out the barrel, insert the other caliber barrel, and retighten. No headspace gauge needed — per Hammerli’s design, headspace is set by the barrel collar.

Can I mount a suppressor on the threaded barrel?

Yes. The barrel is threaded 1/2×28, the standard for .22 rimfire suppressors. Just make sure your can is rated for .22 WMR if you’re shooting magnum loads.

Is this rifle accurate enough for competition?

Yes. The straight-pull action and free-floated barrel give you sub-MOA potential with good match ammo. Many shooters use the Force B1 in NRL22 and PRS Rimfire matches.

Does the combo include both barrels and magazines?

Yes. The limited edition combo ships with a .22 LR barrel, a .22 WMR barrel, and one magazine for each caliber. Check the box contents upon arrival.
