I just finished building my 922r compliant 12 gauge shotgun over the weekend. It runs great! I figured all you gun guys would want to check out the 3 min. video my brother and I made (it's been edited so you'll only see action) of its maiden voyage. We ran a whole lot of 00 Buck and 1 oz. slugs through it. No light loads! This gun is made for zombies! Have fun watching. Take care.
