ALEX MAG AR 17HMR 10-Round Magazine – High-Capacity, Precision-Engineered for AR Rifles

The Alexander Arms 10-round magazine for .17 HMR AR rifles is a purpose-built polymer mag designed specifically for shooters running the company's AR-platform .17 HMR upper receivers. If you've invested in one of these specialized rimfire ARs—known for their flat trajectory, minimal recoil, and laser-like accuracy out to extended range—you know that finding quality magazines built to spec is non-negotiable. This mag delivers the capacity and reliability that precision .17 HMR shooting demands, whether you're zeroing at the bench, competing in rimfire matches, or taking varmints at distance.

Built from durable polymer, the mag feeds reliably and handles the unique dimensions of .17 HMR cartridges without compromise. The 10-round capacity strikes a practical balance for most shooting sessions while keeping your rifle handy in the field. Alexander Arms engineered this magazine to work flawlessly in their .17 HMR uppers, and that focus on compatibility means you're not dealing with feeding issues or fitment surprises.

Because .17 HMR AR setups remain somewhat specialized in the broader rifle market, having dedicated magazines on hand is smart practice—especially if you run multiple uppers or shoot frequently. Many shooters buy in quantity to ensure they've got spares and backups. Alexander Arms typically offers price breaks when you purchase several mags at once, making it economical to stock up.
