Thompson Center Arms 4010R Compass 5+1 204/223 Black Steel/Alumn

The Thompson Center Arms 4010R Compass 5+1 magazine is a factory-engineered replacement designed for shooters who rely on Thompson Center's Compass rifle platform. Built to the same exacting standards as OEM magazines, this 5-round capacity magazine delivers the reliability you need whether you're zeroing a new rifle, practicing at the range, or in the field. The black steel construction pairs durability with a clean, professional look that matches modern Compass builds.

Compatible with both .204 Ruger and .223 Remington chamberings, the 4010R gives you flexibility across two popular varmint and mid-range cartridges. Thompson Center's commitment to tight tolerances means this magazine feeds consistently and seats securely without the wobble or binding that plague poor aftermarket copies. If you own a Compass rifle in either caliber, a spare or replacement magazine is genuine insurance against downtime.

Proper care and routine maintenance will keep this magazine running for years. Clean it alongside your rifle, inspect the feed lips for damage after heavy use, and store it unloaded when not in service. Thompson Center factory magazines are the smart choice over generic alternatives—they're engineered specifically for your rifle's feed system, not designed to fit a dozen platforms at once.
