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 an additional ICS 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 100329 - EK3 Sight Rail (WE/ICS)
