Description
ACM M4 Rubber Knife with Case and Straps (Black)
The ACM M4 Rubber Knife is a black training knife modelled on the M4-style bayonet, supplied with a case and straps for carrying it on your kit. It gives you an authentic military look on your loadout and a safe rubber blade for knife kills at sites that permit them.
The M4-style bayonet is closely associated with the M4 and M16 family of rifles, so this knife is a natural companion for anyone running an M4 replica or a US military-style impression. Being rubber, it flexes on contact rather than cutting, which makes it suitable for airsoft use and for training drills and photographs.
Case and straps
The supplied case keeps the knife secure and protected, while the straps let you fix it to your belt, rig, plate carrier or leg. Check the product images to see the case design and strap arrangement so you can plan where it will sit on your kit.
Knife kills
Where knife kills are allowed, a light touch with the blade, usually on the back or shoulder, is all that is needed, typically with a clear “knife kill” call. Never touch the head or face, and always follow the marshals’ guidance. Some sites ask to inspect rubber knives before play to make sure they are soft enough.
Realism and display
For milsim players and reenactors, a bayonet-style knife on the front of a rig or on the belt is a classic part of a US military loadout. It is also a safe prop for photo shoots and film work.

Compatibility
The case and straps allow mounting on most belts, rigs and plate carriers; review the images and dimensions to confirm the configuration suits your kit. This is a training knife for display and knife-kill games only and is not designed to attach to a replica as a bayonet. Check your site’s rules on rubber knives before bringing it to a game.
Care and maintenance
Wipe the knife and case with a damp cloth after games and let them dry fully. Store the knife in its case so the blade keeps its shape, and avoid leaving it in hot cars or direct sun for long periods, which can make rubber soft or tacky. Replace the knife if the blade tears or deforms.
Who is it for?
Ideal for M4 owners, US military impression players and reenactors, and anyone wanting a safe training knife with a proper case and straps.
Please note: Use only in line with your site’s rules. This is a rubber training knife, not a tool or a functional bayonet.
