Before You Order

Choosing AR-15 Magazines

Caliber, quantity and state.

Caliber

The 30rd magazine runs 5.56, .223 and 300 Blackout. 7.62x39, .22LR, 9mm and .308 need their own magazines from the linked categories.

How Many

Volume pricing rewards buying in fives and tens. A coupled pair on the rifle plus a few in the carrier is a common loadout.

Couplers

The coupler works with the 30rd magazine and most polymer AR magazines of similar width. Do not rest the rifle on a coupled magazine.

State Restrictions

30-round magazines cannot ship to CA, WA, CT, NJ, New York City or Chicago without an FFL address. See our shipping restrictions.

Frequently Asked Questions

  • Does the 30rd magazine work with 300 Blackout?

    Yes. It is designed for 5.56, .223 and 300 Blackout. Subsonic 300 Blackout with heavy bullets feeds best from a magazine with an anti-tilt follower like this one.

  • Is there a bulk discount on magazines?

    Yes. Discounts apply automatically at checkout: 5 percent off at 2 to 4 units, 10 percent at 5 to 9, and 17 percent at 10 or more, which brings the price to $10.12 each. Dealers can contact us for wholesale pricing.

  • What does the magazine coupler do?

    It clamps two magazines side by side so a fresh magazine is already in your hand when the first runs dry. It fits the NSPEC 30rd magazine and similar polymer magazines.

  • Will these magazines lock the bolt back?

    Yes. The anti-tilt follower engages the bolt catch when the magazine is empty.

  • Do AR-15 magazines ship to all states?

    30-round magazines require an FFL address to ship to CA, WA, CT, NJ, New York City or Chicago. Everywhere else they ship directly to you.
