Thompson Center Arms 4140R Icon 3+1 243/6.5Crd/7Mm/308 Black Steel

The Thompson Center Icon magazine is a factory-direct replacement mag built to the exact specifications of the original equipment. If you run a Thompson Center Icon rifle in .243, 6.5 Creedmoor, 7mm, or .308 Winchester, having a reliable spare magazine—or two—keeps you in the field without interruption. This polymer-bodied mag holds three rounds and is engineered to feed flawlessly when your rifle demands it most.

Thompson Center machines these mags to tight tolerances, the same way they manufacture the magazines that ship with new Icon rifles. That precision matters: feed reliability isn't something you want to gamble on, especially when you're hunting or at the range. Proper maintenance keeps these magazines running for years, whether you're swapping them between range sessions or keeping backups in your gun bag for extended hunts.

Black polymer construction resists corrosion and won't rattle loose in a pack or truck bed. The straightforward design loads easily by hand and seats solidly in your Icon's magazine well. For Icon owners, this is the no-hassle way to ensure you always have a fresh mag ready to go.
