Strike Industries ARMAG Standard 33rd 223 Rem/5.56x45mm NATO Black Polymer AR-15 Magazine

The Strike Industries ARMAG Standard is a high-strength polymer rifle magazine designed to feed 223 Rem / 5.56x45mm NATO from any AR-15, M4, or M16 pattern lower. With a 33-round capacity, it bridges the gap between standard 30-round magazines and drum options, giving shooters extra on-board rounds without a major bulk penalty at the bench or in the field.

The body is molded from SI Polymer Extreme, a tough carbonate polymer that holds up to hard use at the range and in harsh conditions. The proprietary AccuRamp first-round feed tray geometry ensures the first round indexes cleanly into the feed lips, so reloads are ready the moment the mag seats home. An anti-tilt follower keeps rounds aligned under uneven pressure, eliminating the wiggle and lock-ups that plague lesser polymer mags regardless of which hand you use to seat the magazine.

Practical handling touches are everywhere: anti-slip finger grooves on both sides give you positive tactile control when inserting the magazine, while the slick side profile slides smoothly into double or even triple-stack magazine pouches. A channel molded into the base plate is cut for magazine pouches with shock cord, providing additional retention during carry. Finished in black and made in the U.S.A.
