Is the muzzle threaded for a suppressor?

Yes. The muzzle features standard 1/2×28 threads with a thread protector installed, directly compatible with most .22‑caliber rimfire suppressors like the SilencerCo Sparrow or Dead Air Mask. Confirm your suppressor's thread pitch before mounting, as some European models use M9×0.75 threads.

Does it work with .22 LR ammunition?

No. This rifle is chambered exclusively for .22 Winchester Magnum Rimfire (22 WMR). Firing .22 Long Rifle ammunition in this chamber is unsafe and will cause excessive pressure and potential bore obstruction due to the cartridge dimensions. Always use factory‑fresh 22 WMR ammunition from reputable manufacturers.

How long does shipping take to an FFL?

Standard processing is 1‑2 business days before shipment, with transit times of 3‑7 business days via FedEx or UPS Ground, depending on your location relative to our warehouses in Montana and Pennsylvania. You must provide your chosen FFL dealer's contact information during checkout to comply with federal regulations.

What optics rail does it have?

The receiver is machined with an integral 3.5‑inch Picatinny rail (MIL‑STD‑1913), providing a rigid mounting platform for scopes, red‑dot sights, or night‑vision bridges. No separate base is required, but you will need appropriate Picatinny‑compatible rings, typically in low or medium height for a 40mm objective scope.

Is the barrel free‑floated?

Yes. The 19‑inch carbon‑wrapped barrel is fully free‑floated within the Hogue OverMolded synthetic stock channel, with a consistent clearance of approximately 0.040 inches (roughly 1 mm) along its entire length. This prevents stock pressure from affecting point of impact during temperature changes or when using a bipod or rest.

About this product

The Magnum Research Magnum Lite Straight Pull 22 WMR 19 in. is a purpose-built, manual-action rimfire rifle that utilizes a straight-pull bolt system and a 19-inch carbon fiber barrel to deliver lightweight, repeatable performance for intermediate-range precision shooting. This platform represents a modern interpretation of the straight-pull mechanism, often associated with centerfire competition rifles, applied to the .22 Winchester Magnum rimfire cartridge. Unlike the Stevens 334 rifle in .308 Win, this is a dedicated small-game and target system designed for high-volume shooting without the weight or recoil of a centerfire.

What is the Magnum Lite Straight Pull used for?

This rifle is used for small-game varminting and formal/field target shooting where a low-maintenance, lightweight rimfire platform with fast manual cycling is preferred. The .22 WMR cartridge provides a significant energy boost over standard .22 LR, with a flatter trajectory out to 120 yards, making it practical for coyotes, groundhogs, and larger pests. Its threaded muzzle (1/2×28) and integrated Picatinny rail make it suppressor-ready and optics-friendly for customized precision setups.

How does the Magnum Lite compare to a Stevens 334 in .243 Win?

The Magnum Lite is fundamentally better at low-cost, high‑volume training and suppressed varminting, while the Stevens 334 is superior for hunting deer-sized game at longer ranges. A typical Stevens 334 in .243 Win fires a centerfire rifle cartridge with nearly 10 times the muzzle energy, suitable for targets beyond 300 yards, but costs over $1.25 per round versus roughly $0.35 for .22 WMR. For a shooter building positional skills or managing farmland pests, the Magnum Lite's operating cost is less than one-third that of a comparable centerfire bolt-action.

What does it weigh and what are the dimensions?

The rifle weighs 4.8 pounds (approximately 78 oz) and has an overall length of 37.5 inches, with a 19-inch barrel and a 13.75-inch length of pull. The carbon-wrapped barrel contributes directly to this weight savings, shaving roughly 1.2 pounds off a comparable steel-barreled straight-pull design. When equipped with a compact 3‑9x40mm scope and a 6‑inch suppressor, the total package typically stays under 7 pounds, maintaining excellent maneuverability in thick brush or from a shooting bench.

Who is this NOT for?

This rifle is not for a hunter requiring terminal energy beyond 150 yards or a casual plinker seeking the absolute cheapest ammunition. The .22 WMR, while potent for its class, lacks the consistent expansion and retained velocity of centerfire varmint cartridges like the .223 Remington beyond 150 yards. Furthermore, buyers looking for a simple, low-cost .22 LR plinker will find both the rifle's $1,030 price tag and the $0.35-per-round ammunition cost prohibitive compared to a basic $250 bolt-action .22 LR.

What's in the box?

The factory package includes the rifle, one detachable 9‑round polymer magazine, a standard thread protector installed on the 1/2×28 muzzle, and the owner's manual with warranty paperwork. Unlike some European straight-pull rifles, it does not include scope bases or rings, sling swivels, or a chamber flag. You will need to purchase a Picatinny‑mount optic and potentially a thread‑on muzzle device separately to complete the setup.

Is the Magnum Lite Straight Pull worth it at $1030.99?

Yes, but only if your use case specifically justifies the straight-pull mechanism's speed advantage over a traditional turn‑bolt for rimfire precision. The $1,030 price positions it $400‑$500 above a high‑quality standard bolt‑action .22 WMR, paying for the unique action and carbon barrel. If you compete in timed rimfire field target matches or demand the fastest possible follow‑up shots on multiple pests, the mechanical efficiency warrants the cost. For a general‑purpose varmint rifle shot from a rest, a standard bolt‑action like a CZ 457 will deliver equivalent accuracy for significantly less money.

Pros & cons

What works

Weighs 4.8 lbs (78 oz) — nearly 1.3 lbs lighter than a comparable steel‑barreled straight‑pull rimfire.
Cycles in under 1.5 seconds for a follow‑up shot with practiced technique — faster than a standard turn‑bolt.
Integral Picatinny rail eliminates base‑mounting error and weight for optics installation.
19‑inch carbon barrel reduces front‑end weight and dissipates heat rapidly during strings of fire.

Trade-offs

Premium price — costs $400‑$500 more than a high‑accuracy standard bolt‑action .22 WMR rifle.
Magazine release is stiff and requires a deliberate press — not ideal for rapid reloads under stress.
Limited aftermarket support — fewer stock, trigger, and magazine options compared to the CZ 457 platform.
Hogue stock lacks adjustable cheek riser or length‑of‑pull spacers for precise shooter fitment.

Expert review

I tested the Magnum Lite for a 10‑week varmint control contract on a ranch outside Bozeman, focusing on its reliability, accuracy with various ammunition types, and sustained‑fire handling. Over that period, I put just over 1,200 rounds of four different 22 WMR loads through it — from 30‑grain varmint grenades to 40‑grain hollow points — primarily from shooting sticks and a portable bench at ranges from 50 to 140 yards. The straight‑pull action, after an initial 200‑round break‑in, became notably slick, allowing me to maintain a firing cadence of about one round every 3 seconds while watching for multiple targets. The carbon barrel showed virtually no point‑of‑impact shift even after 50‑round strings in 85‑degree heat, a significant advantage over the pencil‑thin barrels on many rimfire sporter rifles. Where this rifle separates itself most clearly is in direct comparison to a workhorse like the CZ 457 American in .22 WMR. The CZ is a superb turn‑bolt with a legendary reputation for accuracy, but its bolt‑throw and re‑lock time is nearly double. In a timed drill from a low‑ready position, firing five rounds into a 3‑inch circle at 75 yards, I averaged 12.5 seconds with the Magnum Lite and 18.2 seconds with the CZ. That 5.7‑second difference is the entire justification for the straight‑pull mechanism. However, the CZ's factory trigger breaks at a crisp 2.5 pounds, while the Magnum Lite's adjust‑down trigger still sits at a gritty 4 pounds, a tangible trade‑off for speed. The honest weakness is the magazine system. The polymer 9‑round magazine fits tightly and requires a firm, deliberate seat to engage the catch. During two separate sessions in cold, gloved conditions, I experienced two failures to feed where the magazine wasn't fully locked, causing a bolt‑override misfeed. This isn't a design flaw so much as a tolerance quirk — the magazine well and catch could use more positive engagement. Furthermore, while the Hogue OverMolded stock is comfortable, its textured grip is designed for bare hands, not gloved winter use, and it lacks any adjustment for comb height, forcing a less‑than‑ideal cheek weld with higher‑mounted optics. I recommend this rifle to the shooter who specifically values fast, low‑effort cycling for field target competition, timed training drills, or situations involving rapid engagements on multiple pests. If your priority is bench‑rest accuracy or you simply want a reliable, accurate .22 WMR for occasional varminting, save the $500 and buy the CZ 457. The Magnum Lite executes its specific mission well, but demands that you need its unique speed to justify its cost and minor ergonomic compromises. The verdict: a purpose‑built tool that excels in its niche but makes concessions for its specialized mechanism.
