Metalform Ar-15 Magazine 9mm 32Rd Steel Gray

The Metalform AR-15 Magazine 9mm 32Rd in Steel Gray is a purpose-built, all-steel magazine designed for shooters running 9mm conversions on AR-15 platforms. If you're feeding a 9mm AR build—whether you've gone the Colt-style conversion route or run a Rock River system—this high-capacity magazine gives you 32 rounds of reliable performance without the feeding hiccups that plague lesser designs. Built tough for shooters who demand consistency at the range, in training, or downrange.

The all-steel construction and metal follower are engineered to handle a full load without distortion or creep. That matters: a warped follower or weak spring leads to misfeeds, double-feeds, and the kind of malfunctions that cost you the moment. Metalform's design keeps rounds feeding smoothly from the first shot to the last, so you stay focused on your shooting, not your gear.

The removable floorplate strips down fast for cleaning, inspection, or maintenance—no special tools, no fussing around. If your AR conversion block is set up with a hold-open feature, this magazine will lock the bolt back on the last round, giving you that tactical feedback you're counting on. Compatible with Colt-style and Rock River conversion systems that use a lower receiver conversion block.

Frequently Asked Questions

Will this magazine work with my 9mm AR-15 conversion?

Yes, if your build uses a lower receiver conversion block and is set up for Colt-style or Rock River 9mm conversions. The magazine is designed to feed reliably in those platforms.

Does this magazine work with AR hold-open?

Yes. If your conversion block is fitted with a hold-open feature, this magazine will lock the bolt back on the last round.

How do I clean and maintain this magazine?

The removable floorplate comes off easily without tools, allowing you to disassemble the magazine for inspection, cleaning, and maintenance.

Why choose steel over plastic magazines?

The all-steel construction and metal follower resist deformation under full load, which means more reliable feeding and less worry about wear or creep over time.
