Shot 09 – Dustproof Magazine

Somebody finally figured out a way to keep dust from entering the M4 through the magazine well. Tango Down’s Advanced Reliability Combat magazine has a special lip that seals up the well when locked into place.

A squishy gasket called a “sand seal” shuts out the even the finest dust found in Afghanistan, said Tango Down president Jeff Cahill at Shot Show 09.
But that’s not the only new thing about this polymer magazine.
“It’s a modular design that has never been done before,” Cahill said.
It’s made up of two parts. The portion that goes into the magazine well is straight while the exposed portion is curved. The two parts are bonded together, so they won’t come apart, Cahill promises
The design eliminates friction that occurs when other continuously-curved polymer magazines are inserted into the straight well.
This lets the magazine drop smoothly from the weapon when you push the magazine release button.
The ARC mag also has no removable floor plate for increased strength. It also means you can’t take it apart.
For cleaning, Tango Down has included slots in the follower to let any dirt escape. You soak it in hot, soapy water,  rinse it and let it drain.
The new magazine is the result of four years of work with U.S. SOCOM to develop a magazine for the Special Operations Combat Assault Rifle. SCAR was designed to use the same size magazines as M4.
It will be available in late January for $29.95 each. There will also be a civilian version, without the gasket, for plinking on the range. It’s $24.95. The mags will come in desert tan, dark earth brown, foliage green and clear.
