Check-Mate Industries M1A/M14 Magazine

Check-Mate Industries is the M1A magazine that earns the trust factory Springfield mags get, at a lower price. Check-Mate is a long-time USGI magazine contractor, and its M1A/M14 magazines are built to military specification with a steel body, phosphate finish, and an anti-tilt follower. On a magazine-sensitive platform where bargain mags cause most feeding failures, Check-Mate is the aftermarket option that runs.

The magazines are 100 percent made in the USA and come in 5, 10, 15, 20, and 25-round capacities for everything from hunting-legal configurations to range and duty use. They drop straight into any standard M1A or M14 and lock up with the same rock-and-lock action as the factory mag. For shooters stocking deep, Check-Mate lets you build a magazine inventory without paying full factory price per unit.

Between the factory Springfield mag and Check-Mate, you have the two M1A magazines worth owning. Skip the unbranded steel and aluminum magazines that flood the market; the few dollars saved are not worth the feeding problems they introduce on an otherwise reliable rifle.
