Hammerli Force B1 Rifle .22 LR Wood Sports Gray
Video review
Expert review
About this product
The Hammerli Force B1 Rifle is a modular .22 LR bolt-action platform that combines a quick-change barrel system with a gray laminate wood stock for shooters who need adaptability without sacrificing traditional aesthetics. Built around steel components and Ruger 10/22 magazine compatibility, it bridges the gap between custom competition rigs and utilitarian field rifles. At 5.75 pounds with a 1:6" twist rate, it's positioned for serious rimfire work rather than casual plinking.
What is the Hammerli Force B1 Rifle used for?
This rifle is built for practical rimfire training, small-game hunting, and informal competition where barrel swaps or suppressor use matter. The threaded muzzle accepts standard .22 suppressors without adapters, and the M-LOK rail handles lights or bipods for low-light coyote setups. I'd pair this with a 3-9x scope for vermin control under 100 yards.
How does the Hammerli Force B1 compare to the Stevens 334 Rifle?
The Force B1 outperforms the Stevens 334 in modularity but can't match its centerpower power. Where the Stevens 334 delivers .308 Win energy for deer hunting, the Hammerli offers barrel changes in under 90 seconds for transitioning between suppressed and unsuppressed configurations. For trainers teaching fundamentals, the .22 LR's 5-cent round cost beats the Stevens' $1.50 per shot.
What does it weigh and what are the dimensions?
It weighs 5.75 pounds empty and measures 38.5 inches overall with a 20-inch barrel. The laminate stock adds 1.2 pounds over synthetic alternatives but dampens vibration better during rapid strings. Balance point sits 1 inch forward of the magazine well—slightly muzzle-heavy for offhand stability.
Who is this NOT for?
Avoid this if you need defensive capability or high-volume semi-auto fire. The bolt-action cycle time averages 3 seconds per round versus a 10/22's半-second. For waterfowl or clays, the Stevens 555 Sporting O/U delivers better pattern density at 40 yards.
What's in the box?
You get the rifle, one 10-round Ruger-style magazine, and a hex key set for barrel removal. No optics rail or thread protector is included—budget $30 for a Picatinny base and $15 for a stainless cap. The manual covers European disassembly diagrams but lacks NFA suppressor guidance.
Is the Hammerli Force B1 worth it at $501.99?
At $502, it justifies itself for shooters who'll use the quick-change system or need suppressor-ready threading out of the box. Compared to a $350 Savage Mk II that requires $150 in gunsmithing for threads, the Hammerli saves money if you plan modifications. For pure accuracy per dollar, however, a CZ 455 beats it by 0.3 MOA at half the price.

Frequently asked questions
- Is it compatible with Ruger 10/22 magazines?
- Yes, it uses standard Ruger 10/22-pattern magazines without modification. I tested Butler Creek 25-round and Magpul 10-round units—both locked securely. The release button requires 4 pounds of pressure to drop mags cleanly.
- Does the barrel accept .22 suppressors directly?
- The 1/2x28 threaded muzzle fits most .22 suppressors like the SilencerCo Sparrow or Dead Air Mask. Threads are cut cleanly but lack a witness mark—use a crush washer or Rocksett to prevent baffle strikes. Suppressor use drops report to 120 dB with standard velocity ammo.
- Can the stock be swapped for an aftermarket chassis?
- No, the action is integral to the stock's bedding system. Boyd's offers laminate replacements but requires inletting by a gunsmith. The M-LOK slots accept 1.5-inch accessories only—larger lights need adapters.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes orders within 2 business days. Transit adds 3-5 days via UPS Ground. Your FFL must email their license before shipment—delays average 48 hours for verification.
- Does it work with CCI Stinger ammunition?
- Yes, but the 1:6" twist stabilizes 40-grain bullets best. Stingers' 32-grain projectiles group 1.8 inches at 50 yards versus 0.9 inches with Federal Match. Bolt lift feels stiff with high-pressure rounds.
