The irM4 replicates an M4 in feel and function. The selector switch allows the training rifle to operate in safe, single shot, and three round burst. It can be outfitted with duty sights, lights, stocks and other attachments. The irM4 syncs wirelessly to the irVest to record shot data, accuracy and more. It features a bright muzzle flash, ammunition accountability with the SmartMag, live noise and recoil. The irM4 comes in both standard or short barrel length (pictured above).
