80% Build

Anyone do a GST-9 build in MA? I am looking into it and wanted to see any problems people may have come across.

I'm building one at the moment, just waiting on the trigger and Apex extractor kit.

This guy has a pretty thorough series of vids on the kit. I believe he ran into early wear issues with the front rails and the recoil spring tearing up the frame.

Personally, it's been pretty good, for my 1st 80% build.
