Why buy our products?

Our training rounds are the most realistic in the world and have the correct weight and feel of live rounds, making them the perfect SAFE substitute. Make the most of your time at home by dry-firing, learning the proper function of your firearms, and the muscle memory for clearing a jam. Before spending that “liquid gold” going to the range, make sure your firearms are going to perform properly. Even a change in magazines could make a day at the range a waste of time.

Don’t risk safety, function checking with live rounds! At the range, the best way to train for a tactical situation is the old “ball and dummy drill”. Load a magazine with your normal ammunition, but slip in a few training rounds too, forcing yourself to clear a jam and learning the invaluable skill of getting back into action without stopping to think about it! These are just a few of the reasons you NEED our dummy rounds or “fake bullets”.
