Description
The Savage B22 Precision 22 WMR 18″ MDT Chassis 10-Round is a bolt-action rimfire rifle built for shooters who demand accuracy without the cost of centerfire. Chambered in .22 Winchester Magnum Rimfire (WMR), this rifle pairs an 18-inch heavy, threaded barrel with a Modular Driven Technologies (MDT) billet aluminum chassis. The result is a stable, adjustable platform that holds tight groups at 100 yards and beyond. Per Savage Arms specs, the user-adjustable AccuTrigger lets you dial pull weight from 2.5 to 6 pounds without tools. A one-piece Picatinny rail accepts any optic, and the detachable 10-round rotary magazine feeds reliably. This is a precision rimfire rifle that doesn’t cut corners.

Key Features
- MDT Billet Aluminum Chassis — Why it matters: The rigid, one-piece chassis eliminates flex and gives you a consistent bedding surface for sub-MOA accuracy. The adjustable length of pull and comb height let you dial in fit for any shooting position.
- 18″ Heavy, Threaded Barrel — Why it matters: The heavy profile soaks up heat and vibration, keeping shots consistent round after round. The 1/2×28 threads let you attach a suppressor or muzzle brake for quieter shooting or reduced recoil.
- AccuTrigger — Why it matters: You can adjust trigger pull from 2.5 to 6 pounds without removing the action or using special tools. A crisp, light trigger reduces the chance of pulling a shot off target.
- One-Piece Picatinny Rail — Why it matters: No need for adapter plates or separate rings. Mount any modern scope or red dot directly to the rail for a solid, repeatable zero.
- Detachable 10-Round Rotary Magazine — Why it matters: The rotary design feeds .22 WMR rounds smoothly and reliably, even with the magnum cartridge’s slightly longer case. Quick reloads keep you in the action longer.
Who It’s For
This rifle is for the hunter who wants to practice wind reading and shot placement without burning through expensive .308 or 6.5 Creedmoor ammo. It’s for the varmint shooter who needs a lightweight, accurate rifle to carry across fields for groundhogs, prairie dogs, or coyotes. It’s also for the precision rimfire competitor who wants a ready-to-run chassis rifle without building one from scratch. If you’re a right-handed shooter who appreciates a magnum rimfire that hits harder at longer ranges than .22 LR, this is your rifle.
Pros / Cons
Pros:
– MDT chassis offers full adjustability for length of pull and cheek height.
– AccuTrigger is one of the best factory triggers on the market.
– Threaded barrel makes suppressor mounting easy.
– 10-round magazine gives you more shots between reloads than most rimfire rifles.
– .22 WMR delivers roughly 50% more energy at 100 yards than .22 LR.
Cons:
– The .22 WMR ammo costs about twice as much as .22 LR, so practice sessions add up.
– The chassis is heavier than a traditional wood or synthetic stock, making it less ideal for long hikes.
– Right-hand only configuration limits left-handed shooters.

What is the Savage B22 Precision 22 WMR 18″ MDT Chassis 10-Round best used for?
This rifle is built for precision rimfire shooting, including varmint hunting, target practice, and entry-level competition. The .22 WMR cartridge gives you flatter trajectory and more wind resistance than .22 LR, making it effective for small game and pests at ranges out to 150 yards.
Does this rifle come with a scope?
No, the Savage B22 Precision ships without optics. It has a one-piece Picatinny rail that accepts any standard scope rings or mount. You’ll need to purchase a scope separately.
Can I use .22 LR ammunition in this rifle?
No. This rifle is chambered strictly for .22 WMR (Winchester Magnum Rimfire). Using .22 LR can cause dangerous pressure issues and damage the firearm. Always check the caliber stamped on the barrel before loading.
Is the stock adjustable for left-handed shooters?
The rifle is designed for right-hand operation only. The bolt handle and ejection port are on the right side. Left-handed shooters may find the ergonomics uncomfortable, though the chassis’s length of pull and comb height are adjustable for any shooter.
What is the barrel twist rate?
Per Savage Arms specs, the barrel has a 1:16″ twist rate, optimized for stabilizing 30- to 40-grain .22 WMR bullets commonly used in varmint hunting and target shooting.
