Panzer Arms AR-12 & BP-12 Magazine – 12 Gauge – 10 Rounds – Steel – PA10RM
The Panzer Arms PA10RM (UPC: 8682084099716) is a heavy-duty 10-round extended magazine designed to provide maximum firepower for the Panzer Arms AR-12, AR-12 PRO, and BP-12 (Bullpup) shotguns. Unlike standard 5-round magazines, the PA10RM allows for longer strings of fire, making it a favorite for home defense and competitive 3-gun shooting in 2026. This magazine is constructed from rugged stamped steel with a black oxide finish, providing the structural integrity needed to withstand the heavy recoil of 12-gauge magnum loads while ensuring the feed lips remain dimensionally stable over thousands of rounds.
Engineered for the MKA 1919 / AR-12 platform, this magazine features a high-tensile strength steel spring and a low-friction polymer follower to ensure reliable feeding of both 2 3/4" and 3" shells. The bottom is finished with a high-impact polymer baseplate that provides additional shock resistance when dropping magazines on hard surfaces during rapid reloads. Because many Turkish-manufactured shotguns share the same magazine interface, the PA10RM is widely cross-compatible with several other popular platforms, including the VR-series and GForce shotguns, making it one of the most versatile 12-gauge box magazines on the market today.
Includes: (1) Panzer Arms 10-Round Steel 12 Gauge Magazine.
Key Features
- 10-Round Extended Capacity: Doubles the standard capacity of most factory-supplied magazines for significantly increased hit potential.
- All-Steel Body: Built with heavy-gauge steel for professional-grade durability; far more resistant to feed lip deformation than polymer alternatives.

- 3-Inch Chamber Support: Optimized to reliably cycle both standard 2 3/4" field loads and heavy 3" magnum slugs or buckshot.
- Last Round Bolt Hold Open: Features the necessary geometry to engage the bolt catch on compatible AR-12 platforms, indicating an empty chamber.
