Special Features
- The Power Bedding integral bedding block system positively locks the receiver into the stock and free-floats the barrel, a combination that removes stock-induced pressure points and produces consistent shot-to-shot accuracy from a factory rifle.
- The Ruger Marksman Adjustable trigger is user-adjustable between 3 and 5 lbs of pull weight with no gunsmithing required, letting the shooter dial in a break that matches their shooting style.
- The 60-degree bolt throw provides a short, fast cycling stroke that keeps your hand close to the grip and clears most standard scope objectives without risking contact.
- Two interchangeable stock comb modules are included, one standard height and one high comb, so the rifle fits correctly whether you run a low-mount rimfire optic or a taller scope setup.
- The receiver-mounted bolt release allows the bolt to be removed without pulling the trigger, a design feature that adds a layer of safety during field unloading and cleaning.
- The flush-mounted JMX-1 rotary magazine keeps the profile clean and snag-free, and the rifle also accepts the higher-capacity BX-15 Magnum magazine for extended range use.
Practical Benefits
- The 16.10-inch barrel keeps the overall length at 35 inches, making this rifle easy to carry through brush, load into a vehicle, or set up on shooting sticks in tight quarters.
- The 5.3 lb weight reduces fatigue on long hunts and makes this a natural fit for younger shooters or anyone who spends extended time behind the rifle.
- The threaded muzzle is compatible with a wide range of 1/2-28 suppressors and muzzle devices, making the Ruger American Rimfire (8393) a ready-to-suppress platform right out of the box.
- The adjustable comb and 13.75-inch length of pull fit a broad range of adult shooters, and the compact overall length works well for younger hunters moving into their first centerfire-caliber alternative.
- The .17 HMR cartridge shoots flat past 150 yards with minimal wind drift compared to .22 LR, giving you a meaningful reach advantage for varmints and small game at field distances.
- Whether you are hunting prairie dogs, shooting steel at 200 yards, or introducing a new shooter to precision bolt-action rifles, your Ruger American Rimfire (8393) gives you a factory-accurate platform built to perform beyond its price class.
The Ruger American Rimfire (8393) in .17 HMR is a capable tool for the varmint hunter or precision rimfire shooter who wants a suppressor-ready, accurate bolt gun in a compact, field-ready package.
