TangoDown ARC Magazines

A basic problem for plastic magazines is that they have to have a constant curved interior to be molded in one piece. There is no other way. But the magazine well of the M16/AR-15 weapon system is straight. So much compromise has to be reached from a design standpoint to make the two work together. So side effects of magazines not dropping free, are often seen. The optimum solution would be a straight upper section to properly present cartridges through the magazine well, and a constant-radius lower section to accommodate remaining ammunition. However, this design has been impossible to produce in polymer… until now.

The patent pending two-piece modular construction allows us to create the ultimate magazine for many reasons. In addition to the proper magazine form, we are able to achieve maximum strength and integrity when the components are molded. Precision molding is achieved much easier on two small parts versus one large one. We can also mix materials, impossible with conventional plastic magazines. We can offer transparent lower/high tensile strength upper sectioned magazines that avoid the brittle feed lip issue of all-transparent material construction. Modular construction makes perfect sense for the unprecedented strength- we eliminated the removable floor plate, so the magazine becomes a five-sided box. ARC Mag survives the impact that crushes metal magazines.

ARC Mag takes full advantage of the latest polymers available from the aerospace industry- materials impervious to the effects of solvents & lubricants. After molding, we permanently bond the two sections together with advanced adhesives during manufacturing, so no disassembly is possible, or required. ARC Mag has a unique low-friction semi-floating follower that is slotted to allow for easy magazine cleaning. Just dunk the ARC Mag in hot soapy water, rinse and invert to drain. That’s hassle-free maintenance. ARC Mag also features a premium Chromium-Silicon spring that is heat treated stress relieved and Moly coated that is tested to 100,000 cycles.

Our design team created a magazine that could be handled by the operator in any condition- note the aggressive ridges front and rear. They allow a positive purchase when seating the ARC Mag. The deep waffle pattern on the magazine’s sides assist in rapid extraction from mag pouches. Every surface on the ARC Mag was given careful consideration to help out the operator.

Specifications:

For 5.56 x 45mm cartridges, capacity is true 30 rounds. Fits AR-15/M16/M4/SCAR Light series weapons.
Heavy duty feed lips provide smooth, positive round delivery.
Unique Patent-pending follower is skeletonized for easy magazine cleaning without disassembly.
Semi-floating follower is molded in low friction polymer, and utilizes proper anti-dive shape.
Premium quality chromium-silicon spring is heat treated, stress relieved and moly coated. Spring life is 100,000+ cycles.
Patented modular design and construction allows for maximum part integrity during the injection molding process.
Dimensions are tightly controlled, allowing the magazine to drop free, even from non MIL-STD receivers.
Modular design allows for material choice flexibility. Transparent lower sections can be bonded to the high-strength upper sections without sacrificing feed lip durability. Lower sections have no floor plate to fail if loaded magazine is dropped on hard surfaces. Rugged five-sided box construction provides superior impact resistance. Color is molded in, with no coating to chip or wear off.
Proprietary polymer has been successfully impact tested from -40 degrees F to +150 degrees F. It is unaffected by gun lubricants and solvents.
Ultra high strength adhesive permanently bonds both sections together. Joint is stronger than the base material.
Patented, durable EVA sand seal prevents entry of environmental contaminants into the weapon system (Military model only).
Molded-in ridging, front & rear, assures positive grip on magazine during ‘push-pull’ insertions.
Deep ribs on sides enable sure grip on magazine during mag pouch extractions.
