5KU Zenitco Handguard Spacer for E&L AK Airsoft Replicas

When fitting a replica Zenitco Sport handguard made by 5KU on an AK-105 airsoft AEG replica made by E&L, I had a lot of struggle. The rear mounting block needed to be filed down a lot to fit into the AK receiver. The handguard wouldn't fit all the way in, there was a gap between the handguard and the receiver. This is a spacer to fill that gap, make the handguard fit tight and smooth out the difference in dimesions a bit.

I believe this should be applicable for any other AK replica made by E&L and any other Zenitco handguard replica made by 5KU. In case you need to tweak the dimensions a bit, there's also the file in STEP format.
