I will definitely check this.
Just checked a GI stock in this area, and the firing pin has been hitting it. The receiver is even relieved in this area. Never had a problem here, but it doesn't hurt to relieve the area.
If the handguard area wasn't butched, I find no problems with the "Korean" type stock. Lots of time with a sander and it is GTG.
