This hop-up unit from Echo1 replaces the original hop-up unit in any Echo1 M14. This will also fit the Tokyo Marui and UTG M14 airsoft rifles.
This hop-up unit is an ideal replacement for any deformed or damaged hop-up units. If your hop-up unit doesn't work, is missing pieces, or tends to jam your AEg, this hop-up chamber should get you back to running normal.
This hop-up unit will only fit Tokyo Marui and clone M14 AEGs. It will not fit the G&G or CA M14 airsoft rifle.
