Magpul 5.56x45mm NATO polymer snap caps let you safely practice rifle function, feeding, and extraction without the risk of accidental discharge. Whether you're breaking in a new AR, diagnosing a malfunction, or simply running dry-fire drills at home, these inert dummy rounds are an essential tool for any 5.56 owner. They're precision molded to match the critical dimensions of Remington .223/5.56mm NATO ammunition, so they cycle and eject reliably through your magazine and chamber—just like live rounds, but without the boom.
The glass-fiber reinforced polymer construction is tough enough to handle repeated feeding and ejection, yet it won't damage your rifle's components. Unlike steel or brass snap caps, Magpul polymer won't rust, won't corrode your gun, and won't leave corrosive residue behind. They're also a smart way to safely practice dry-firing—letting you work trigger control and presentation without wearing out your firing pin on empty chambers or risking a negligent discharge in your home or at the range.
Each 5-pack gives you enough snap caps for serious training or to keep a spare set on hand. They work with any magazine that takes standard 5.56mm ammo, making them compatible with most modern rifles and carbines in that caliber. Grab a pack and add them to your cleaning kit, training bag, or range bag—they're one of those simple, low-cost tools that pays for itself the first time they save you from a training mistake.

Yes. Magpul 5.56 snap caps are precision molded to duplicate the dimensions of Remington .223/5.56mm NATO ammunition and work with any rifle, magazine, or carbine chambered in 5.56 NATO or .223 Remington.
Yes. These polymer snap caps are designed specifically for safe dry-fire practice. The glass-fiber reinforced polymer construction won't damage your firing pin the way striking an empty chamber can.
No. The polymer material won't rust itself and won't cause corrosion on your rifle's internal parts, making them safer for long-term storage and repeated use compared to some metal alternatives.
Simply load them into your magazine and run them through your rifle just as you would live ammunition. They cycle and eject like real rounds, allowing you to identify feeding, extraction, or magazine issues without firing live ammunition.
