Magpul Industries Corp Tmag Ar15 Gen3 556 20Rd Odt
The Magpul TMAG Gen M3 AR15 magazine in ODT (Olive Drab Tan) is a 20-round, translucent 5.56x45mm NATO magazine built for shooters who want reliability without sacrificing visibility. Purpose-designed for Colt-spec AR-15 and M4 platforms, this magazine works across a wide range of modern rifle systems—including HK416, FN SCAR MK 16/16S, M27 IAR, IWI Tavor, and many others that follow STANAG 4179 geometry. If you're running drills at the range, hunting with an AR variant, or simply building a dependable magazine locker, the TMAG Gen M3 delivers the straightforward performance Magpul is known for.
The translucent body is the standout feature here: you can visually verify your round count and ammunition type at a glance, a genuine convenience whether you're managing multiple loads for different ranges or hunting scenarios. The frosted polymer won't fog or yellow under normal use, and the ribbed front and rear straps provide positive grip during reloads—crucial when you're working fast or in less-than-ideal conditions. The four-way, anti-tilt follower keeps rounds stacked reliably even after hundreds of cycles, and the USGI-spec stainless-steel spring with painted coil is built to last.
The magazine body is factory-marked to show approximate round counts when seated in your rifle, and the paint-pen dot matrix lets you add your own reference marks if you want to track partial loads or specific ammunition lots. The low-profile floor plate opens up compatibility with Magpul's ecosystem of floor-plate accessories, so you can swap out witness holes, bumpers, or tactical grips as your setup evolves. Straightforward, honest gear for serious shooters.
