Product Description

The Beta Mag is a revolutionary twin-drum high-capacity magazine. It has a 60,000-round service life, stores indefinitely while loaded without loss of performance. Cleaning and lubrication are the only maintenance required.

These mags are manufactured to the highest international production standards. They meet or exceed all applicable U.S. and NATO Mil-Specs. The state-of-the-art design operates smoothly and without malfunction and they even deploy in all weather environments and field conditions.
Successfully tested in combat during Desert Storm where it performed flawlessly under the most rigorous conditions. The 100-round capacity of the C-MAG drastically reduces vulnerability during magazine changes, while dramatically increasing survivability.

They load like a standard magazine, by hand or with the BETA personal loader or speed loader. It snaps into the weapon and releases by the standard magazine catch without modifications. The streamlined profile improves weapon handling and maneuverability.

BETA C-Mag Systems enhance the weaponry of peacekeepers around the world, gives military forces and law enforcement agents a critical edge, and adds an extra dimension of force in any tactical engagement.
Law enforcement and security operations find that the C-MAG magazine's high capacity and pre-loaded storage capabilities reduce loss of life and property damage. They also provide tactical sustainment and in turn, area containment.

List of Part Numbers

There are eight major components to this design

1: Interchangeable Feed Clip Assembly- serves as an adapter for the specific weapon within caliber. During loading, cartridges are inserted on top of the spacer rounds, through the feed clip and into the drums.

2: Top Spacer Round- tapered to allow the weapon bolt to close after the last round is fired.

3: Spacer Round Strings (Two included)- fill the feed clip before and after firing and are an integral part of the magazine. String length varies depending on choice of feed clips.

4: Rotary Drive Gears- feed rounds from alternate drums to maintain a dynamic weight balance while firing.

5: Feed Clip/Housing Juncture- splits cartridge column evenly into the drums into two concentric rows.

6: Housing Cover-available in solid black or clear styles. (We do not offer both for some items)

7: Feed Clip Strap- secures the interchangeable feed clip assembly to the C-MAG housing.
