The Magpul® TMAG 30 AR/M4 GEN M3 Translucent Magazine is a top-notch addition to your loadout. Built for STANAG-compatible firearms chambered in 5.56x45mm and .223 Rem, this magazine is molded from translucent material with a smokey hue. This allows you to easily check your round counts and what type of ammo you have in the magazine. The ribbed front and rear straps offer improved purchase during magazine changes while the smooth sides boost visibility. Rounds are pushed up by a 4-way, anti-tilt follower and a durable USGI-spec, stainless steel spring with a painted coil. The low-profile floor plate is compatible with Magpul floor-plate accessories (not included). The magazine's body is marked for approximate round counts even when inserted into magwells. Make your aftermarket markets with the paint-pen dot matrix. This magazine is optimized for AR-15 and M4 platforms but permits operation with other firearms as well.
