Description

Hammerli has been building precision rimfires since 1863, and the Force B1 is the brand's way of shaking up a market full of look-alike .22s. Instead of a traditional turn-bolt, you get a toggle-style straight pull action pulled straight from biathlon-style competition guns. Cycle it with a quick flick of the wrist and you stay on the scope between shots, which makes plinking sessions faster and follow-ups on small game a whole lot easier.

The Force B1 Quick-Change Barrel System

The headline feature here is the toolless barrel swap. Pull back the knurled locking collar in front of the receiver, slide the barrel out, and drop in another one. An alignment tab mates the barrel to the action the same way every time, so it locks up consistently. That opens the door to running .22 WMR or .17 HMR barrels down the road without buying a whole new rifle. The 16.1 inch .22 LR barrel comes threaded 1/2×28 with a knurled thread protector, so adding a suppressor or other muzzle device takes about thirty seconds.

Familiar Parts, Fresh Platform

Hammerli made a smart call borrowing from the Ruger 10/22 ecosystem. The Force B1 feeds from 10/22-style rotary magazines and ships with two 10-rounders, and the trigger group accepts 10/22-pattern replacements if you ever want to upgrade. The magwell is sized to handle both .22 LR and .22 WMR length rotary mags, coordinating with whichever caliber barrel you have installed.

A Stock That Fits Everybody

The black synthetic stock adjusts for both length of pull and comb height without tools, covering roughly 14.6 to 16.6 inches of pull. That means one rifle can fit a new shooter on Saturday and a full-grown adult behind a magnified optic on Sunday. Up top, a machined-in Picatinny rail gives you a rock-solid mounting platform for a scope or red dot, and at 5.75 pounds the whole package carries easily on a squirrel woods walk or a day at the range.

Frequently Asked Questions

Does the Hammerli Force B1 use Ruger 10/22 magazines?

Yes, it feeds from standard Ruger 10/22-style rotary magazines and ships with two 10-rounders. The magwell is actually sized for the longer .22 WMR rotary mags, so .22 LR magazines use a small clip-on spacer to fill the gap. The trigger group is also 10/22-pattern compatible, so aftermarket trigger upgrades drop right in.

Can I swap the Force B1 to other calibers?

That is the big draw of this rifle. The toolless quick-change barrel system lets you pull the barrel by retracting a knurled collar, and Hammerli offers barrels in .22 LR, .22 WMR, and .17 HMR for the platform. An alignment tab indexes the barrel the same way every install, and testing has shown point of impact stays remarkably consistent between swaps.

Is the Force B1 suppressor ready?

It is. The 16.1 inch barrel comes threaded 1/2×28, which is the standard pitch for rimfire suppressors and muzzle devices, and a knurled thread protector is included. Paired with subsonic .22 LR ammo, the straight pull action makes for a genuinely quiet setup since there is no semi-auto action noise.

Does the Hammerli Force B1 come with sights?

No iron sights are installed on this model. Instead, the receiver has a Picatinny rail machined directly into the top, giving you a sturdy, integral mounting platform. Plan on adding a rimfire scope or red dot before your first range trip.
