Hexmag HX Shorty AR-15 Magazine - .223 Rem, 5.56x45mm, 300 AAC Blackout Polymer

The Hexmag HX Shorty AR-15 magazine is a compact polymer option built for shooters who need reduced capacity without sacrificing reliability. Chambered in .223 Rem, 5.56x45mm NATO, and 300 AAC Blackout, this 10-round magazine delivers the dependability serious AR-15 users expect, whether you're running a short-barreled rifle for tactical work, home defense, or hunting in tight spaces. Hexmag's polymer construction has earned trust across the shooting community for durability and consistent feeding.

The Shorty format makes this magazine ideal for situations where compact gear matters—think vehicle storage, dense hunting cover, or any rifle build where a lower profile helps. Ten rounds is the legal magazine capacity in several states, making this mag compliant for hunters and shooters in those jurisdictions while maintaining full reliability in other regions. The polymer body resists corrosion and abuse better than bare metal, and field-proven Hexmag engineering keeps your rifle running when it counts.

If you run an AR-15 in multiple calibers or are building a dedicated .300 Blackout upper, the HX Shorty's cross-platform compatibility saves you money and keeps logistics simple. This is not a compromise magazine—it's a purpose-built choice for shooters who understand that sometimes smaller is smarter.
