Savage B22 Magnum Precision .22 WMR Chassis Rifle

Description

You know that feeling when you’re trying to stretch a .22 LR’s legs on a windy Missouri day, and it just gets pushed around? I’ve been there. I wanted a rimfire that could reach out with authority, handle prairie wind, and still be affordable to feed. That’s the exact scenario that led me to the Savage B22 Magnum Precision. This isn’t your plinker’s .22; it’s a purpose-built, chassis-based rifle designed to wring every bit of accuracy and performance out of the potent .22 WMR cartridge.

The Savage B22 Magnum Precision, 22 WMR, 18″ Threaded Barrel, Black Color, Black MDT Chassis, 10Rd, Detachable Box Magazine, AccuTrigger is a modern precision rimfire rifle. It combines Savage’s reliable bolt action and excellent AccuTrigger with a rigid, feature-rich MDT chassis system, all chambered in the flat-shooting .22 Winchester Magnum Rimfire cartridge. It’s a ready-made platform for the serious small-game hunter, varminter, or rimfire precision shooter who demands more than a standard sporter can offer.

Let’s start with the foundation: the MDT chassis. This isn’t just an aesthetic upgrade. That black MDT chassis provides a rock-solid, aluminum-reinforced bedding platform that free-floats the 18-inch threaded barrel. The result is consistent, repeatable accuracy because the barrel isn’t touching anything it shouldn’t. The ergonomics are fantastic, with a fully adjustable comb and length of pull via spacers. I’ve put a few hundred rounds of various 40-grain loads through it, and the stability this chassis offers from a bench or bipod is immediately noticeable. It feels like a centerfire precision rig, just in a smaller, more economical package. The rifle ships with a 10-round, detachable box magazine that feeds smoothly—a huge plus for follow-up shots.

The heart of the system is Savage’s proven B22 action. It’s smooth, it’s simple, and it’s topped off with the excellent AccuTrigger. Here’s the thing—for a rifle at this price point, having a user-adjustable trigger that breaks cleanly at a light pull is a massive advantage. You can tune it to your preference without a trip to the gunsmith. The 18-inch barrel is the perfect length for the .22 WMR, balancing maneuverability with full powder burn, and the threaded muzzle (1/2″-28) is ready for a suppressor or muzzle device right out of the box. No gunsmithing required to add your preferred rimfire can, which is a game-changer for noise reduction and keeping your shooting spot discreet.

Weighing in at approximately 7.5 pounds without optics, it has a substantial, stable feel. The .22 WMR cartridge itself is the star. Compared to standard .22 LR, it has significantly more energy, less wind drift, and a flatter trajectory out to 150 yards and beyond. This makes it a formidable choice for coyotes, foxes, or groundhogs at extended rimfire ranges where a .22 LR would struggle.

Pros: The MDT chassis offers incredible stability and adjustability for the price. The AccuTrigger is best-in-class. The .22 WMR chambering provides real-world performance advantages over .22 LR. The threaded barrel is a welcome standard feature. At $496.22, it represents serious value in the precision rimfire space.

Cons: Ammo cost is higher than .22 LR. The chassis system adds weight compared to a traditional stock, which might not be ideal for long carries if you’re strictly a walk-and-stalk hunter. You’ll need to budget for a quality optic and rings to match the rifle’s capability.

This rifle is for the shooter who has outgrown their basic .22 and wants rimfire performance that bridges the gap to centerfire. It’s for the varminter who needs reliable hits on small, wary targets past 100 yards. It’s for the new shooter looking to learn precision fundamentals on a platform that feels like a “real” tactical or competition rifle, but without the cost and recoil. It’s also a fantastic suppressor host for quiet, effective pest control.

Frequently Asked Questions

Q: Is the MDT chassis compatible with other B22 models or aftermarket parts?

A: The chassis is specific to the Savage B22 Magnum Precision model. However, many AR-style components are compatible, like pistol grips—the chassis uses a standard AR grip pattern, so you can swap in your favorite from brands like Magpul or Hogue.

Q: What kind of accuracy can I expect with .22 WMR ammo?

A: With quality ammunition, sub-MOA groups are absolutely possible from a rested position. The chassis and trigger remove many variables, letting the barrel and ammo do their job. I’ve seen consistent 0.8-1.1″ groups at 100 yards with several premium hunting loads.

Q: Can I use .22 Long Rifle ammunition in this rifle?

A: No. This rifle is chambered specifically for .22 Winchester Magnum Rimfire (.22 WMR). It is not safe to fire .22 LR, .22 Short, or .22 Long in this chamber. Always use the correct, specified ammunition.
