6 Dummy Trainer NATO 5.56x45 and .223 Remington Ammo Rounds

These rounds have primers that have been detonated, all powder removed, and an FMJ (full metal jacket) bullet correctly reseated into a brass case that has been taper-crimped. They employ once-fired brass that has been correctly resized, so minor dings are sometimes present. Regardless, each round will properly and safely chamber in all firearms of the specified caliber, with the benefit of being completely inert.

Dummy rounds are employed by firearms training organizations in marksmanship exercises due to the safety they provide when live rounds could otherwise potentially injure or kill if misused or mishandled by the inexperienced. From malfunction exercises, gun-handling drills, to classroom work, these are ideal.

Mixed with live ammunition during more advanced training, dummies can provide beneficial information to the instructor who is looking for anticipatory movements that are handicapping a shooter’s accuracy. The detonated primer helps differentiate them from live rounds when used in those types of drills.

Dummies are also very useful when practicing loading, unloading, and immediate action maneuvers. Whenever the chance of unintended discharge exists, a dummy round is always a much better choice than the live equivalent.

Additionally, dummy rounds like these provide excellent cushioning during dry fire. There is never any guarantee that a firing pin will not be damaged, but the base of these dummies will help dampen any inertia much better than an empty chamber.

Also, for those who would like to set up a permanent period display with the ammunition that matches their military collectables, these provide a superb and safe alternative to live rounds, that might accidentally end up in the wrong place.

Finally, there is no substitute for dummy rounds when actions are being tested for functionality during gunsmithing operations. Checking magazine feed, chambering, extraction, and ejection are always best performed with a round that poses no threat of firing inadvertently.
