The Element One Piece hop-up unit for M4 or M16 is constructed out of a durable polycarbonate and features o-rings for enhanced air seal. This hop-up chamber also fits all CA M15 models.
Airsoft weapons can sometimes look very realistic and could easily be mistaken for a real weapon. To avoid such confusion, all airsoft weapons are required to have a vibrant orange tip no shorter than six (6) millimeters from the end of the muzzle. Any tampering with the required orange tip will result in a total void of warranty and could even result in legal consequences.
