How to use: This M4A2 dummy replica is great for training. You can carry it around just like a real rifle using the 1 - 1/4″ swivel sling mounts. Hold it firmly and practice your stances and movements. Note: Since it's a dummy replica, don't use it in real - combat situations. Also, avoid dropping it from high places as it may cause damage. Maintenance: Keep it clean by wiping it with a dry cloth regularly. Store it in a cool and dry place to maintain its durability.
