AC-Unity MP5 40-Round Magazine

40-Round MP5 Magazine

The AC-Unity MP5 magazine holds 40 rounds of 9x19mm in a curved polymer body built for the HK MP5 family and its clones. It gives you ten more rounds than a standard 30-round MP5 magazine, so you reload less often on the range or in a carbine course. A clear strip down the side shows how many rounds are left without unloading.

Features

• 40-Round Capacity — The extended curved body holds 40 rounds and is marked AC-MP5-9x19-40RDS on the side.
• 9x19mm Caliber — Chambered for 9x19mm, the same cartridge sold as 9mm Luger or 9mm Parabellum.
• Polymer Resin Body — The magazine is molded from German polymer resin, which keeps it light and resists dents that can bend a steel magazine out of shape.
• Clear Witness Window — A transparent strip with numbered count marks runs the length of the body so you can see your remaining rounds at a glance.
• Carbon Wire Spring — A carbon wire follower spring pushes each round up into the feed lips, the curved edges at the top that hold the cartridges in place until the bolt strips one off.
• Wide Temperature Rating — It is rated for use from -76°F to +140°F (-60°C to +60°C).
• Fits MP5-Pattern Firearms — Compatible with the HK MP5, MP5K, SP5, HK94 and clones built to the same magazine pattern.
• Loader Compatible — Works with the Maglula MP5 magazine loader and universal pistol-caliber speed loaders.
• Black Finish — The magazine is black throughout, matching the standard furniture on most MP5-pattern guns.

Build and Compatibility

AC-Unity makes this magazine in Bosnia and Herzegovina. The polymer body follows the MP5 magazine profile, including the rear catch notch that locks it into the magazine well, so it seats in HK firearms and MP5 clones that take factory-pattern magazines. Unloaded, it weighs roughly 4.2 to 4.9 oz, depending on the production run.
