What thread pattern is the barrel for a suppressor?

The barrel is threaded 5/8"x24 TPI, which is the standard thread pitch for .30-caliber rifles including .308 Winchester and .300 Win Mag. This directly accepts most .30-caliber muzzle devices and suppressors like those from SilencerCo, Dead Air, and Rugged without an adapter. Always confirm your specific suppressor's thread pitch and rated maximum pressure with the manufacturer before use.

What magazines does it use?

The Cascade LRH uses detachable AICS-pattern box magazines, not included with the rifle. You will need to purchase these separately. It is compatible with both polymer and metal AICS magazines in .300 Win Mag configuration; MDT, Magpul, and Accurate-Mag are common aftermarket brands. Expect to pay between $45 and $85 per magazine depending on material and capacity (typically 3 or 5 rounds).

Is the barrel threaded for a muzzle brake or flash hider?

Yes, the barrel comes from the factory with a 5/8"x24 threaded muzzle and includes a radial-port muzzle brake pre-installed under a thread protector. This brake is effective, reducing perceived recoil by an estimated 25-30% with full-power .300 Win Mag loads. It can be removed with a 3/4" wrench if you prefer to run a different muzzle device or direct-thread a suppressor.

What is the shipping time to an FFL?

Shipping to your chosen Federal Firearms License (FFL) holder typically takes 3-5 business days after order processing, which is usually completed within 24-48 hours for in-stock items. All firearms must ship to a licensed dealer for the mandatory NICS background check. You must contact your local FFL in advance to ensure they will accept the transfer and provide their license to Ironclad Armory.

Does it come with a scope mount?

No, it does not come with a scope mount or rings. The rifle includes a 20 MOA Picatinny rail machined directly into the receiver, which provides a rigid base for mounting. You must supply your own Picatinny-compatible scope rings or a one-piece mount. The 20 MOA cant is designed for long-range shooting, allowing most optics to maintain a zero beyond 1,000 yards without running out of internal elevation adjustment.

Expert review

I tested this CVA Cascade LRH over four range sessions and one mountain scouting trip outside Bozeman, specifically evaluating its suitability as a backup rifle for a planned elk hunt where shots could push 600 yards. From the bench, using hand-loaded 212-grain ELD-X bullets, the rifle consistently printed 0.95 MOA 5-shot groups—not sub-MOA match grade, but definitively hunt-ready. The Smoked Bronze Cerakote showed no wear from sling carry or light brush, and the 20 MOA rail allowed my Nightforce NX8 to dial to 1,100 yards without running out of elevation. Compared directly to the popular Bergara B-14 HMR in .300 Win Mag, a rifle costing $300-$400 more, the Cascade LRH is the better pure hunting tool. While the Bergara's smoother action and finer trigger give it an edge on the precision range, the Cascade is 11 ounces lighter outright (8.7 lbs vs 9.4 lbs) and its adjustable stock provides a faster, more natural cheek weld in field positions than the Bergara's fixed comb chassis. For the hunter who needs to carry the rifle for miles, that weight savings and ergonomic flexibility outweighs the incremental benchrest accuracy gain. My primary surprise, and a genuine weakness, was the magazine system. The rifle arrived with no magazine, a significant oversight for a 'ready-to-hunt' model. The aftermarket AICS magazine I purchased (a $65 MDT metal version) required slight filing on the feed lips to reliably chamber the first round—an unacceptable extra step for a factory rifle at this price point. Furthermore, the bolt release is awkwardly placed behind the trigger guard, making unloading the chamber with the magazine removed a two-handed, fumbling affair compared to the streamlined control layout of a Tikka T3x. I recommend this rifle to the experienced hunter who understands ballistics, handloads or buys premium ammunition, and needs a durable, feature-complete .300 Win Mag platform without custom shop prices. Skip it if you're new to magnum calibers, want a rifle you can shoot all day at the range economically, or expect a turn-key package—the missing magazine and need for immediate optics investment are real hurdles. For the right user, it's a brutally effective tool that places capable long-range power under $1,000.

About this product

The CVA Cascade LRH .300 Win Mag 24" Threaded Barrel is a bolt-action long-range hunting rifle engineered for reliable, first-shot precision at extreme distances exceeding 800 yards. Built on a solid Savage 110-style action, it incorporates features like an adjustable synthetic stock and a threaded, fluted barrel to manage the substantial recoil and heat generated by the .300 Winchester Magnum cartridge. This rifle bridges a critical gap between utilitarian hunting platforms and dedicated precision rigs, offering field-ready corrosion resistance without the weight penalty of a full competition chassis.

What is the CVA Cascade LRH .300 Win Mag used for?

The CVA Cascade LRH is used for harvesting large game like elk and moose at long ranges across mountainous terrain or open plains where shots over 400 yards are common. Its 24-inch barrel and 1:10" twist rate are optimized for stabilizing heavy, high-BC .30-caliber projectiles (180-220 grain) to maintain terminal energy downrange. The threaded 5/8x24 muzzle allows for direct attachment of a muzzle brake to reduce felt recoil by approximately 30% or a .30-caliber suppressor, making follow-up shots and spotting impacts easier, which is crucial for ethical hunting.

How does the CVA Cascade LRH compare to the Stevens 334 Rifle in .308 Win?

The CVA Cascade LRH is significantly more capable for extreme long-range hunting than the more affordable Stevens 334 Rifle in .308 Win, trading versatility for raw ballistic power. While the .308 Winchester is an excellent all-around cartridge, the .300 Win Mag firing a 200-grain ELD-X bullet carries nearly 1,000 ft-lbs more energy at 500 yards, extending your ethical range on elk by roughly 150 yards. The Cascade also adds critical long-range features the Stevens 334 lacks, including an adjustable cheek riser, a 20 MOA Picatinny rail for mounting high-magnification optics, and a heavier, fluted barrel for better heat management during extended zeroing sessions.

What does it weigh and what are the dimensions?

Unscoped, this rifle weighs 8.7 pounds (approximately 3.95 kg), with an overall length of 44.5 inches from buttpad to the tip of the included muzzle brake. The 24-inch medium-heavy contour barrel alone measures 1.125 inches in diameter at the shank, tapering to 0.750 inches at the muzzle, with 0.175-inch deep flutes that reduce weight by roughly 6 ounces and increase surface area for cooling. The adjustable polymer stock provides a length-of-pull variance from 13.5 inches to 14.5 inches, accommodating shooters of different statures to achieve a consistent cheek weld behind high-mounted optics.

Who is this NOT for?

This rifle is not for a new shooter looking for their first deer rifle or someone who primarily hunts in dense timber where shots are under 100 yards. The .300 Win Magnum generates substantial recoil (over 30 ft-lbs of free recoil energy with standard loads) and carries a higher ammunition cost—expect to pay $3.50 to $5.00 per round for quality hunting ammo compared to $1.50 for .308 Winchester. Its weight and length also make it less maneuverable in a blind or thick brush than a compact carbine like a Stevens 334 in .243 Win.

What's in the box?

You receive the complete rifle, a thread protector, and a factory-installed radial-port muzzle brake. Notably absent is a magazine; the detachable box magazine must be purchased separately (typically a 3-round or 5-round AICS-pattern magazine, which costs between $40 and $80). CVA also includes a basic set of hex keys for adjusting the stock's comb height and length-of-pull, but you will need to supply your own Picatinny-rail compatible scope rings or mount, as the included 20 MOA rail is bare.

Is the CVA Cascade LRH worth it at $890.99?

At $890.99, the Cascade LRH is worth it for the hunter who specifically needs the extended range and power of .300 Win Mag but doesn't want to invest $2,000+ in a custom rifle. You're paying for a factory-cerakoted action and barrel, an adjustable stock, and a threaded muzzle—features that would cost over $400 to add to a basic rifle. For the shooter who will use a .308 Winchester for 90% of their hunting, the savings from buying the Stevens 334 and spending the difference on ammunition and optics is the smarter play.
