The Hammerli Force B1 rifle’s unique, spring-loaded locking collar enables barrels to slip into and out of the action quickly and easily.


The star of the show is the quick-change barrel, which is toolless and can transition between barrel lengths and calibers, from .22 LR to .22 WMR. To initiate the barrel change, simply pull down on the external collar located on the Force B1. This straightforward motion unlocks the barrel without the need for any tools, streamlining the process and allowing for rapid adjustments.

As for the straight-pull bolt action, it is a biathlon-style mechanism that emits minimal noise when manipulated. Setting this toggle-style straight-pull action apart from the pack is its ability to provide a solid lockup during operation. This ensures that the rifle maintains its alignment shot after shot. The shooter experiences a seamless pull and push motion, enabling fast follow-up shots with ease.

The Hammerli Force B1 uses a biathlon-style bolt handle, which is a polymer extension that extends out and down from the articulating lever that allows the bolt to travel back and forth in the receiver.


For seamless caliber coordination, the Force B1 rifle employs an adaptable magwell with Hammerli’s adapter system and, with the use of the correct Ruger rotary-style magazine, offers a a flawless fit.

More about the quick-change barrel system from Hammerli: “The innovative barrel mounting system is a testament to Hammerli’s commitment to precision and user-friendly design. By eliminating the need for tools, the Force B1 ensures that you can adapt to changing scenarios without sacrificing the pinpoint accuracy that defines Hammerli firearms. This toolless approach to barrel changes enhances the rifle's versatility, making it a true asset in dynamic environments.”

More features include an adjustable stock, so that shooters can customize length of pull (14.6 to 16.6 inches) and adjustable two-height universal cheekpiece to customize comb height, a threaded 16.1-inch barrel (½x28 TPI) with thread protector that can accommodate muzzle devices and suppressors, a Picatinny optic rail, a fore-arm with M-Lok attachment points under the rail, quick-detach pockets in the stock for attaching a sling, plus a trigger that is compatible with Ruger 10/22-style trigger groups. Trigger pull is adjustable from 4.4 to 5.8 pounds. In addition, a 20-inch barrel is available.

Several stock options will be available in the future, including wood-laminate models, but the basic Hammerli Force B1 model shown here has a stock molded from black polymer.
