We have used this item and it is the best on the market! There are cloth and plastic versions all over the market. They are crap! This mag coupler is made from metal and your magazines will break before the mag-grip lets go of them.

DOUBLE YOUR FIREPOWER!!!

Machined, aluminum, bar stock clamp holds two twenty- or thirty-round, .223 caliber magazines side-by-side, for rapid reloads. Provides a strong, secure coupling that prevents the spare magazine from shifting or working loose. Tough enough to withstand the demands of tactical and competition use.
