If you’re looking for a 5.56/.223 AR-15 magazine that’ll let you stop shooting when you’re *good and ready* to stop shooting, then stop shopping. We’ve got ProMag’s American-made 40-round best in the house. If it were any longer, it’d probably have to be a drum!

This magazine’s key feature isn’t visible from the outside. That’s its roller follower, which has two sets of wheels to help it move up and down seamlessly and avoid jamming. Like the body of the mag itself, the follower is made of DuPont Zytel. It’s a popular thermoplastic for making handgun frames, vehicle parts, sporting goods, and many other components that need to be tough, lightweight, corrosion-proof, heat-resistant, and crush-resistant.

Get a grip! ProMag’s “roller mag” has aggressively stippled sides and edges so your hands have more to latch on to. Make sure your gun’s OD green before ordering this magazine – unless you specifically want contrasting colors, that is.

This is a high-capacity magazine. Don’t risk getting arrested: Know where it’s illegal, and know better than to take it there.
