ak handguard spacer

I ordered an ak handguard set from Apex to fit on my airsoft replica. The lower handguard is a little out of spec compared to a real one. It did fit the airsoft, but had some play. The rear tab that slides into the front of the receiver is smaller. It's also missing the spring at the front that pushes against the handguard retainer.

I modeled up some spacers to make the handguard a snug fit. The rear spacer slides into the front of the receiver. There's no need to glue it in. The front spacer sandwiches between the handguard and retainer. This one doesn't need to be glued to the handguard, but probably should to make assembly and disassembly easier.

The thickness of the front spacer might need to be changed. In the slicer just scale the z height.
