One of the fastest designs I've ever did but i couldn't find it anywhere.

This is an adapter for any glock gen 4/5 slide to use a gen 3 spring guide. Mainly for the use of a compensator or an aftermarket tm spec one. The hole is a tiny bit bigger to accomadate for the springguide slightly moving when compressing.

This has been tested on different glock models from WE and VFC and all types of aftermarket spring guides.

you can print it however you like.
