CVA Cascade SB .223 Rem 18 in Threaded Bolt Rifle 4rd
About this product
What is the CVA Cascade SB .223 Rem 18 in Threaded Bolt Rifle? The CVA Cascade SB is a legally defined short-barreled rifle (SBR) platform, measuring an overall length of 34.5 inches with its threaded 18-inch 4140 carbon steel barrel and weighing a practical 6.8 pounds unloaded. It's a dedicated .223 Remington/5.56 NATO bolt-action system designed from the ground up for suppressor use and close-quarters applications. For those navigating the regulatory paperwork of an NFA item, this rifle offers a purpose-built solution rather than a modified long gun.
What is the CVA Cascade SB .223 Rem used for?
This rifle is engineered primarily as a suppressed, compact-action tool for varmint control and tactical training courses. The 5/8x24 threaded muzzle and 70-degree bolt throw are spec'd for rapid follow-ups with a can, while the 18-inch barrel maintains enough velocity for ethical shots on coyote-sized targets out to 250 yards. It's a logical choice for a truck gun or for hunters working from permanent blinds where 37-inch rifles are cumbersome.
How does the CVA Cascade SB compare to the Stevens 334 Rifle in .308 Win?
The Cascade SB is substantially more specialized for suppressed, sub-100-yard work than the general-purpose Stevens 334. While our Stevens 334 in .308 Win is a better choice for hunters needing terminal energy on deer at 300+ yards, the CVA's lighter 6.8-pound weight, shorter 34.5-inch overall length, and direct-thread suppressor compatibility make it superior for moving through thick brush or vehicles. The Stevens offers more caliber versatility, but the CVA is a dedicated tool for a specific job.
What does it weigh and what are the dimensions?
It weighs 6.8 pounds unloaded, with an overall length of 34.5 inches and a barrel length of precisely 18 inches. Those dimensions are critical for NFA item paperwork and for fitting in a standard 36-inch rifle case with a suppressor mounted. The barrel is 4140 carbon steel with a 1:9 twist rate, and the stock's length of pull is a standard 13.5 inches, which most adult shooters will find serviceable without adjustment.
Who is this NOT for?
This is not for a first-time gun buyer or someone unwilling to complete ATF Form 1 or Form 4 paperwork. If your primary use case involves long-range precision beyond 400 yards, the .223 cartridge and 18-inch barrel are limiting factors. It's also a poor fit for shooters who prioritize aftermarket stock compatibility, as the Cascade action uses a proprietary inlet that locks you into CVA's factory options, unlike the more universally compatible Stevens 334 platform.
What's in the box?
You receive the barreled action seated in the Veil Tac Black synthetic stock, one 4-round detachable AICS-pattern magazine, and the installed two-piece Weaver scope bases. CVA does not include thread protectors, a scope, rings, or a bore snake. Plan for an immediate additional $40-$60 investment for a quality thread protector or muzzle device to prevent crown damage during transport, as the exposed threads are a point of vulnerability.
Is the CVA Cascade SB worth it at $737.99?
At $737.99, it represents solid value for a turn-key, factory-built SBR platform, saving you the $200 tax stamp, gunsmith fee, and wait time of cutting down a longer rifle. Compared to building a similar rifle from a bare action and aftermarket stock, you're paying a $150 premium for convenience and warranty support. If your use case specifically involves suppressed shooting in confined spaces, the value proposition is clear; if you want a versatile do-everything rifle, look elsewhere.

Pros & cons
What works
- Weighs 6.8 lbs — nearly a full pound lighter than many 20-inch barrel bolt-actions in the same class
- 18-inch barrel with 5/8x24 threads — ready for suppressor attachment without additional gunsmithing
- 70-degree bolt throw — allows for faster cycling compared to the traditional 90-degree throw found on rifles like the Ruger American
- Includes a 4-round detachable AICS-pattern magazine — superior to blind magazine systems for tactical unloading
Trade-offs
- Proprietary stock inlet — severely limits aftermarket chassis or stock upgrades compared to Remington 700-pattern actions
- No thread protector included — an essential $15-$30 part must be purchased separately to protect the muzzle crown
- 1:9 twist rate — marginal for stabilizing the heaviest 75+ grain .223 bullets preferred for longer-range suppressed shooting

Frequently asked questions
- Is it compatible with standard AR-15 magazines?
- No, it uses a proprietary AICS-pattern detachable magazine. The included magazine holds 4 rounds of .223 Remington, and spares are available directly from CVA or retailers like MidwayUSA for approximately $35 each. It will not accept PMAGs or any other standard AR-15 magazine.
- Does the barrel have a recessed target crown?
- No, the 18-inch barrel features a standard, non-recessed crown protected by the 5/8x24 threads. For maximum accuracy when shooting unsuppressed, you should install a thread protector or muzzle brake. The lack of a recessed crown makes the muzzle more susceptible to incidental damage during field use compared to some precision rifle barrels.
- What is the thread pitch for suppressor mounting?
- The muzzle is threaded 5/8x24, which is the standard for .30 caliber rifles. This means you will need a suppressor with a 5/8x24 direct-thread mount or a compatible muzzle device like a keymo adapter. Most suppressor manufacturers, including SilencerCo and Dead Air, offer mounts in this thread pitch.
- Is the receiver drilled and tapped for a scope rail?
- Yes, it comes from the factory with two-piece Weaver bases already installed and torqued. The receiver is also drilled and tapped with a standard Remington 700 short-action footprint, allowing you to replace the included bases with a Picatinny rail from manufacturers like EGW or Warne if desired. The holes are 8-40 thread size.
