Hello everyone, just thought i would get yalls opinions on SDI's firearms courses. I recently enrolled in the advanced gunsmith certification program. Ive tinkered on many firearms throught the years but would not consider myself a gunsmith by any means. I was about to lose my GI Bill in the next couple of years so i figured i would give this a go. Anyone have any experience with this program or insight. I would like to get as much out of this course as possible. Thanks
