Pro-Shot 12SC Snap Caps 12 Gauge Shotgun with #5/16-27 Thread Brass/Cotton Mop - Pack of 2

Pro-Shot 12SC snap caps for 12 gauge shotguns are essential dummy rounds for dry-fire practice, function testing, and firearm maintenance without live ammunition. If you're a shotgun owner who regularly practices at the range, works on your gun at the bench, or simply wants to keep your shotgun's action smooth and reliable, snap caps let you cycle your gun safely and repeatedly without the cost and mess of firing live rounds. This two-pack includes brass-headed snap caps with spring-loaded firing pins designed to handle the striker impact of a 12 gauge shotgun.

The kit also includes a mop attachment with a #5/16-27 thread that screws onto the snap caps themselves. The cotton mop is treated with natural lanolin, which works as a built-in bore cleaner and rust preventative when you push it through the barrel and chamber. This two-in-one approach means you can dry-fire to your heart's content while simultaneously running a protective swab through the bore—a smart way to maintain your shotgun between cleanings or during extended practice sessions. If you want additional rust protection, you can apply a light gun oil like Zero Friction to the mop before use.

Pro-Shot snap caps are a workhorse addition to any shotgunner's kit, whether you're training, diagnosing feeding issues, or simply keeping your gun conditioned and ready. At this price point and with two caps per pack, they're practical enough to leave in your cleaning box or range bag.
