Magpul PMAG M3 10rd 5.56/.223 AR-15 Magazine

Magpul PMAG M3 10-round Magazine — Rifle Magazine

The Magpul PMAG M3 is a 10-round polymer magazine for .223 Remington / 5.56x45mm NATO cartridges. It stores and feeds up to ten cartridges for AR-15/M4-compatible platforms and related rifle designs.

Designed to provide a lower-profile magazine option for users of AR-15 and M4 pattern rifles, the PMAG M3 addresses the need for a durable, serviceable magazine that fits typical AR-style receivers and magazines wells. It is commonly used in range, training, and duty-style configurations where a 10-round capacity is required or preferred.

• Caliber: .223 Rem / 5.56×45 NATO
• Material: Polymer body for reduced weight and resistance to corrosion
• Finish/Color: Black
• Spring: Long-life stainless steel spring for corrosion resistance and consistent feeding
• Follower: Four-way anti-tilt follower to support reliable cartridge alignment
• Floorplate: Flared, easy-to-disassemble floorplate for extraction and improved drop protection
• Geometry: Redesigned bolt catch notch and an over-travel stop on the spine to reduce over-insertion and increase bolt catch clearance on compatible weapons

Specifications & Construction

The PMAG M3 uses a polymer construction with internal stainless steel spring and a four-way anti-tilt follower. The magazine is produced in a black finish and is manufactured in the USA. It features a removable, flared floorplate for maintenance and handling. Specific external dimensions and weight are not provided in the supplied product data.

Compatibility & Intended Use

Primary fit: AR-15 / M4 pattern rifles. The PMAG M3 is optimized for Colt-spec AR-15/M4 platforms but has modified internal and external geometry permitting operation in a range of additional weapons listed by the manufacturer, including HK 416/MR556A1/M27 IAR, British SA-80, and FN SCAR Mk 16/16S. Typical setups include primary rifles configured for range use, training, patrol, or duty where a 10-round magazine is required.
