You can use accessory hose to make silencers for those small m-4s released from 2002-2005 . You can also use it for Frosbite's rifle. Just measure how big you want the silencer to be. Clip the accessory hose. If one end is jagged use that end to slowly place over the rifle barrel. Do it slowly so the accessory hose doesn't puncture. Now you have the CAR-15 Stalker used in Vietnam. Also good for those little Hasbro M-4s
