TangoDown ARC/L-001C - 30 Round AR-15 Magazine - 5.56 NATO


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.  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 creates the ultimate magazine for many reasons.  In addition to the proper magazine form, maximum strength and integrity are achieved when the components are molded.  Precision molding is achieved much easier on two small parts versus one large one.  Materials can also be mixed, impossible with conventional plastic magazines. These magazines avoid the brittle feed lip issue of all-single material construction magazines.  Modular construction makes perfect sense for unprecedented strength.  The removable floor plate is eliminated, so the magazine becomes a five-sided box, allowing it to survive the impact that normally crushes metal magazines.

The ARC Mag takes full advantage of the latest polymers available from the aerospace industry, using materials impervious to the effects of solvents & lubricants.  After molding, the two sections are permanently bonded together with advanced adhesives, so no disassembly is possible, or required.  The 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.  The ARC Mag also features a premium stainless steel spring with a life expectancy of 100,000+ cycles.

This magazine can 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.
