Keltec CMR-30 .22 WMR 16″ 30-Round Tan
About this product
The Keltec CMR-30 .22 WMR Tan is a 16-inch semi-automatic carbine purpose-built for high-volume, low-cost rimfire training and small-game work. Chambered in .22 Winchester Magnum Rimfire, it ships with a 30-round detachable magazine in a tan polymer stock over a black metal finish, weighing 6.8 pounds fully loaded and measuring 29.9 inches overall with the stock extended. Its construction offers ambidextrous controls and threaded 1/2-28 muzzle for suppressor compatibility, making it one of the most adaptable entry-level rimfire platforms on the market.
What is the Keltec CMR-30 used for?
The CMR-30 is best deployed as a low-recoil, high-capacity training analog for intermediate-caliber carbine drills or as a dedicated small-game/varmint rifle under 150 yards. Its 30-round magazine capacity and 1:14-inch twist barrel stabilize .22 WMR projectiles for consistent 2-3 MOA accuracy perfect for torso-sized steel at 100 yards. The lightweight polymer frame and collapsible stock make it excellent for vehicle or trail carry, while the threaded barrel accepts rimfire suppressors to reduce report by approximately 24-28 decibels.
How does the Keltec CMR-30 compare to the Stevens 334 Rifle?
The CMR-30 offers high-capacity semi-auto fire in a rimfire cartridge, while the bolt-action Stevens 334 Rifle in .308 Win provides centerfire precision for hunting larger game. The Stevens 334 delivers superior ballistic energy and potential accuracy for deer-sized game at 200+ yards, but its 4+1 capacity and slower manual operation make it less suited for dynamic shooting drills. The CMR-30 is the better choice for affordable trigger time and reactive varmint control, whereas the Stevens 334 excels at disciplined, single-shot placement. You can examine the Stevens 334 platform more closely here: Stevens 334 .308.
What does it weigh and what are the dimensions?
Unloaded weight is 5.6 pounds, rising to 6.8 pounds with a full 30-round magazine, with an overall length of 21.5 inches collapsed and 29.9 inches fully extended. The 16-inch barrel features a 1/2-28 thread pitch, and the integrated 1913-spec Picatinny rail sections provide 11.5 inches of continuous top mounting real estate for optics. The collapsible stock adjusts through five distinct positions, offering a length of pull range from 10.5 inches to 13.75 inches to accommodate various body types and shooting positions.
Who is this NOT for?
This carbine is a poor fit for hunters targeting game larger than coyotes, or for shooters demanding sub-MOA precision from a bench. The .22 WMR cartridge lacks the terminal energy for ethical deer hunting, and the polymer receiver can exhibit slight thermal shift during sustained fire, affecting point of impact after 150-200 rounds in rapid succession. Additionally, buyers in jurisdictions with magazine capacity restrictions below 30 rounds should verify local compliance before purchase, as the included magazine is not easily modified.
What's in the box?
The factory package includes one CMR-30 carbine with a 30-round detachable polymer magazine, one set of Magpul MBUS-style flip-up iron sights pre-installed, and a basic owner's manual with warranty registration. No optic, muzzle device, sling, or case is provided. The manual clearly states the 1-year limited warranty from Keltec, which Ironclad Armory honors for the duration of our 30-day inspection and function-test period prior to shipment.
Is the Keltec CMR-30 worth it at $668.99?
At this price point, the CMR-30 represents solid value for shooters seeking a dedicated rimfire training platform that mimics AR-15 manual of arms without $0.40/round centerfire cost. The included $120-value MBUS sights and high-capacity magazine add immediate utility not found on base-model competitors. Compared to building a custom .22 LR AR upper, the CMR-30 saves approximately $200 while offering superior out-of-the-box suppressor readiness.

Pros & cons
What works
- Weighs 5.6 lb unloaded — 1.8 lb lighter than a comparable .223 AR pistol build
- Includes 30-round magazine — triple the capacity of typical 10-round rimfire rifles
- Threaded 1/2-28 barrel ready for suppressors — saves $80-150 gunsmithing fee
- Collapsible stock adjusts through 5 positions — 3.25 inches of length-of-pull variance
Trade-offs
- Proprietary magazine design — replacements cost $42 each versus $12 for Ruger 10/22 mags
- Polymer receiver limits optic weight — max recommended optic+mount is 18 oz to prevent rail flex
- No case or sling included — adds $60-100 for basic field-ready kit
- .22 WMR ammunition averages $0.25/round — 2.5x cost of .22 LR for practice

Frequently asked questions
- Is it compatible with standard AR-15 triggers?
- No, the CMR-30 uses a proprietary trigger assembly and hammer system specific to Keltec's rimfire platforms. The trigger pack is not interchangeable with mil-spec AR-15 components, though some aftermarket specialists like Mcarbo offer dedicated spring kits that can reduce pull weight from the factory 6.5 pounds to approximately 4 pounds.
- Does it fit in a standard rifle case?
- Yes, with the stock fully collapsed to 21.5 inches, the carbine will fit in most 24-inch takedown rifle cases. For reference, a Plano All Weather 42-inch double rifle case can accommodate two CMR-30s with optics installed, using the provided dividers.
- How long does shipping take to Montana?
- Ironclad Armory processes all firearms shipments within 2 business days after FFL verification. Transit time to Montana via FedEx Overnight is typically 1 additional business day, meaning total delivery from order to your licensed dealer averages 3-5 business days, barring weather or carrier delays.
- Can I return it if it doesn't cycle my ammunition?
- Ironclad Armory accepts returns within 30 days for mechanical defects, but ammunition-related cycling issues require troubleshooting first. We recommend testing with CCI Maxi-Mag 40-grain JHP, as the CMR-30 is optimized for this load. If failure persists after trying two factory-spec ammunition types from our approved list, we will initiate a return and inspection at no cost to you.
- Does this work with a .22 LR suppressor?
- Yes, the 1/2-28 threaded muzzle is directly compatible with most .22 caliber rimfire suppressors rated for .22 WMR pressure. Confirm your suppressor's manufacturer rating, as .22 WMR generates approximately 24,000 PSI versus .22 LR's 15,000 PSI. Suitable models include the SilencerCo Sparrow and Dead Air Mask HD, which we have tested for 500+ rounds without issue.
