This is a component part of the EK3 rail system. You should only order this part if you need to mount an existing EK3 rail system to a new G&G or Army Armament airsoft gun.
This part is the mount block which holds the EK3 on to the rest of your airsoft gun. If you are using the EK3 with *multiple* airsoft guns, you will need to buy the correct mount blocks and/or sight rails to go with it.
The correct sight rail for use with this mount block is order code 100327 - EK3 Sight Rail (G&G)
