If you run a Thompson Center Compass in a small-bore caliber, this factory magazine is the real deal. The Thompson Center Compass rotary magazine works exactly like the one that shipped with your rifle, so you're not guessing about fit or function. It's engineered specifically for the Compass platform, not some universal magazine forced into a magazine well that doesn't quite work right.
The rotary mechanism stacks rounds in a circular pattern, which does two things. First, it keeps the overall size down and lets the magazine sit flush with your stock so it won't catch on gear or your shooting support hand. Second, that circular stacking gives you five rounds of capacity while keeping the profile low-profile enough that the gun handles and balances naturally. You get practical capacity without the bulk of a traditional box magazine.
Construction combines steel and aluminum in a black finish, which means this magazine handles field use without picking up rust or corrosion issues. The materials balance durability with weight, so you're not carrying anything unnecessarily heavy. The engineering is tight enough that loading and feeding are straightforward without wobble or excessive play once seated in the well.
This specific mag version handles the small-bore trio: .204 Ruger, .223 Remington, and 5.56 NATO. Whether you're running one of those cartridges for varmint work, target practice, or general centerfire shooting, this magazine feeds them reliably. The 5-round capacity keeps things practical and matches what the Compass platform was designed around. Having a spare or two on hand means you're ready to keep shooting without fumbling with loose rounds between sessions.
This magazine is designed specifically for Thompson Center Compass bolt-action rifles chambered in .204 Ruger, .223 Remington, or 5.56 NATO. Check your rifle's barrel marking to verify the chambering. It won't fit Compass rifles in other calibers like .308, 6.5 Creedmoor, or .270, as those use different magazine bodies.
Yes. This is a genuine Thompson Center factory replacement magazine manufactured to the same specifications as the original equipment. It ensures proper fit, reliable feeding, and the same performance as the magazine that came with your rifle from the factory.
No. Load only the caliber your specific rifle is chambered in. While this magazine is listed as multi-fit compatible with .204 Ruger, .223 Remington, and 5.56 NATO, you must match it to your rifle's chambering. Never mix different cartridges in a single magazine.
The rotary design stacks rounds in a circular pattern, creating a more compact package that sits flush with your stock. This means better balance and handling, and the magazine won't snag on gear or support hands. Standard box magazines are taller and wider, which changes how the rifle handles.
