Rifle Round Holder
Quick access to ammunition transforms bolt action and break action shooting scenarios. When magazine capacity restrictions or equipment limitations create challenges, having spare rounds positioned right at the breech eliminates fumbling and delays. Our round holder family delivers this capability through secure rail-mounted storage that grips ammunition by case body diameter.
The line comes in two mounts and two sizes. M-LOK versions attach to M-LOK slots. Picatinny versions mount to a standard 1913 rail and are shaped for slim break action rifles like the CVA Scout: they need a narrow receiver body or shroud, and a standard AR-width body or a wide lever-action handguard won't clear them.

The Guide
Choose Your Mount Type
Select based on your rail system. M-LOK versions attach to M-LOK slots. Picatinny versions mount to a standard 1913 rail but need a narrow receiver body or shroud, like the CVA Scout's; a standard AR-width body or a wide lever-action handguard won't clear them.
- M-LOK for rifles with M-LOK slots
- Picatinny for slim rifles with a 1913 rail, like the CVA Scout
- Picatinny versions don't clear a standard AR-width body or a wide lever-action handguard; those rifles take M-LOK
Determine Your Size Category
Find your cartridge in the lists. As a rough guide, the holder grips the case body just above the rim, but how tightly a round sits varies by cartridge.
- Intermediate: .223 / 5.56, 300 Blackout, .30-30 (tight on purpose), 7x30 Waters, .350 Legend (loosens with use) and .360 Buckhammer
- Large: 6mm ARC, .243, 6.5 Creedmoor, 7mm-08, .308, .270, .30-06, 7mm Rem Mag, .300 Win Mag, .400 Legend, .44 Magnum, .444 Marlin, .45 Colt, .454 Casull, .450 Bushmaster, .45-70, .500 S&W and .410 shells

Match to Your Application
Consider your primary use case when selecting. Break action applications benefit from slim profiles, while bolt actions can accommodate various sizes.
- CVA Scout and other slim break actions: Picatinny versions
- Hunting applications prioritize quick access positioning
- Competition use benefits from secure retention during movement
Verify Rail Compatibility
Ensure adequate rail space and clearance around the mounting area. Consider optics, other accessories, and stock configuration when planning placement.
- Check for interference with existing accessories
- Verify rail length accommodates holder dimensions
- Consider optimal positioning for your shooting style
Field manual
How do I know which size fits my cartridges?
Find your cartridge in the lists below. Intermediate fits .223 Remington / 5.56 NATO, 300 Blackout, .30-30 Winchester, 7x30 Waters, .350 Legend and .360 Buckhammer. Large fits 6mm ARC, .243 Winchester, 6.5 Creedmoor, 7mm-08, .308 Winchester / 7.62×51 NATO, .270 Winchester, .30-06 Springfield, 7mm Remington Magnum, .300 Winchester Magnum, .400 Legend, .44 Magnum, .444 Marlin, .45 Colt, .454 Casull, .450 Bushmaster, .45-70 Government, .500 S&W Magnum and .410 bore shotgun shells. The .30-30 sits tight in the Intermediate on purpose, .350 Legend starts tight and loosens with use, and those cartridges sit too loose in the Large. As a rough guide, Intermediate grips case bodies of about 0.375 to 0.42 in (9.5 to 10.7 mm) and Large about 0.43 to 0.53 in (10.9 to 13.5 mm), measured just above the rim. If your cartridge isn't listed, contact us before ordering and we'll tell you which size to get.
Will the round holder work with my CVA Scout?
Yes, with the Picatinny versions. They mount to a standard 1913 rail and are shaped for slim break action rifles like the CVA Scout, which has a narrow receiver body. That shape is also their limit: a standard AR-width receiver or shroud, or the wide handguard on many lever actions, won't clear them. Those rifles take the M-LOK versions. Choose Intermediate or Large by your cartridge's case body diameter.
How secure is the retention system during use?
The holder grips each round by its case body, firmly enough to keep rounds in place while you walk, climb into a stand or shoulder the rifle. It still lets you pull a round out with your fingers without fighting it. If a round feels loose, check that you have the right size for its case diameter.
Can I mount multiple round holders on the same rail?
Yes, if you have sufficient rail space and proper clearance between mounting points. Consider the dimensions of each holder and verify no interference with optics, other accessories, or stock configuration. Multiple holders can provide storage for different cartridge types or additional capacity for extended sessions.
What is the difference between M-LOK and Picatinny versions?
M-LOK versions attach directly to M-LOK slots. Picatinny versions mount to a standard 1913 rail, but they are shaped for slim break action rifles and need a narrow receiver body or shroud; a standard AR-width body or a wide lever-action handguard won't clear them. Both are the same size and hold three rounds the same way, so a cartridge that fits one fits the other. Choose M-LOK if your rifle has M-LOK slots, and Picatinny for a slim rifle with a 1913 rail, like the CVA Scout.
How do I position the round holder for optimal access?
Mount the holder where you can naturally reach without breaking shooting position or losing sight picture. For bolt actions, position near the action for smooth cycling. For break actions, place within easy reach of your support hand when opening the action. Consider your shooting style and rail space when determining optimal placement for quick, natural access.
Will the holder interfere with my existing accessories?
Check dimensions and clearance requirements before mounting. Round holders are designed with compact profiles, but verify no interference with optics, bipods, or other rail-mounted accessories. The Picatinny versions are shaped for slim break action rifles and need a narrow receiver body or shroud; on a standard AR-width body they won't fit. Plan your rail layout to accommodate all accessories with proper spacing.
Can the round holder handle different cartridge lengths in the same size category?
Yes, the holder grips by case diameter rather than cartridge length, so various lengths within the same diameter range will fit securely. For example, the Large size holds both .308 Winchester and .45-70 Government despite their different lengths. How tightly a round sits still varies by cartridge, so check the cartridge lists in the sizing answer above.
