ETS Magazine AR-15 Gen 2 with Coupler - 30-Round Polymer for 223 Remington, 5.56x45mm, 300 AAC Blackout

The ETS Magazine AR-15 Gen 2 with Coupler is a 30-round polymer magazine designed for .223 Remington, 5.56x45mm NATO, and .300 AAC Blackout platforms. Built with reliable function and real-world durability in mind, this magazine combines a translucent polymer body with practical design features that work for hunters, competition shooters, and tactical users who need dependable ammunition management without breaking the bank or adding weight to their kit.

The Gen 2 geometry improves feed lip compatibility across different AR-15 receivers, so you're more likely to get reliable feeding across a wider range of upper assemblies and bolt carriers. The built-in coupler system lets you link multiple magazines together in seconds without tools—a genuine convenience when you're prepping stages at a match or organizing mags for a long day at the range. The improved over-insertion tab increases retention in mag pouches and carrier pockets, reducing fumbles and lost rounds downrange.

The translucent body isn't just for looks: you can count remaining rounds and identify ammo type at a glance, which matters when you're managing multiple loads or tracking what you've shot. The non-tilting follower ensures reliable bolt-open on the last round, and the specially designed floorplate disassembles without tools for fast cleaning and maintenance. Ergonomic grip ribs give you positive purchase in and out of pouches, and the included dust cover keeps dirt out during storage. Advanced polymer engineering delivers extreme impact resistance, chemical resistance, and temperature stability from cold to heat and UV exposure—no brittle failures from winter range sessions or truck bed storage.

Frequently Asked Questions

Will this magazine work in my AR-15?

The Gen 2 design is engineered with improved feed lip geometry for better compatibility across a wider range of AR-15 receivers. That said, no magazine is 100% compatible with every upper assembly ever made. If you have a particularly tight or loose upper, test one before committing to a full set.

Can I use this magazine with .300 AAC Blackout?

Yes. This magazine is rated for .223 Remington, 5.56x45mm NATO, and .300 AAC Blackout. It holds 30 rounds across all three calibers.

How do the couplers work?

The built-in coupler lets you connect two magazines together in seconds with no tools or extra hardware. Once coupled, you've got extended capacity and faster reloads without fumbling with separate linking hardware.

Is this magazine translucent? Can I see how many rounds I have?

Yes. The polymer body is translucent, so you can see your remaining round count and identify ammo type without opening or unloading the magazine.
