Introducing the Brass Beam - the ultimate dry fire training tool for firearm enthusiasts. With this innovative device, you can turn your firearm into a laser training tool that allows you to practice your shooting skills in the comfort of your own home. The Brass Beam is designed to be inserted into your firearm, where it replaces a regular round. When the firing pin strikes the back of the Brass Beam, it creates a laser pulse that is recorded by the Brass App software. This allows you to analyze your performance and improve your technique, without ever having to fire a live round. Thanks to its compact size and easy-to-use design, the Brass Beam is perfect for both novice and experienced shooters. It's an affordable way to hone your skills and improve your accuracy, whether you're a law enforcement officer, competitive shooter, or just looking to improve your skills for personal defense. This product is a Class 3R laser that complies with ICE 60825-1:2014. 2.6mW MAX OUTPUT at 653nm. Included are 1.5v Button cell batteries. Available on Apple App Store & Google Play now.
