This shim is designed for use with the Blackthorn SEF ambidextrous housing for the MP5. It addresses alignment issues and oversized selector holes that prevent secure fitting of SEF selector levers.

Features:

Use two shims per housing.
Compatible with SEF polymer levers and Magpul MP5 ESK.
Some light sanding or fitting may be required.
If using a factory SEF lever, material may need to be removed from the selector-side shim to accommodate the safety mechanism.

This shim enhances the stability of your setup, eliminating trigger pack and selector wobble.
