Ao Mag Thompson Rifle 9Mm 20Rd Stick

The Auto Ordnance 20-round 9mm stick magazine for Thompson rifle platforms delivers reliable feeding and straightforward capacity for shooters who own or operate the Thompson M1 lightweight carbine. If you've got a Thompson in 9mm, you need magazines that work—and this is one of the OEM-spec options that does. Whether you're at the range, in the field, or just want backup mags on hand, a dedicated 20-round magazine rounds out your loadout.

Stick magazines are iconic to the Thompson platform: straight, simple, and proven. This 9mm version locks into your rifle's magazine well with the same reliability you expect from classic American design. Twenty rounds gives you solid capacity without the bulk of drum magazines, making it practical for extended sessions or hunting situations where you want ammo in the gun without excess weight.

Keep a few of these in rotation. Magazines wear out with use and age; having spares means you're never left short if a follower fails or a feed lip gets dinged up. The 9mm Thompson remains popular with shooters who appreciate its balance of handling, accuracy, and low recoil—and that means keeping your mags in good shape matters.
