My dad just got this huge extension to his gun and i was like what the hell is that for? He just said to follow him. I did and we have a small backyard with people surrounding us in all directions. He attached it to his shotgun and said watch this. He fired three rounds straight into a couple bags of chicken feed. I was ammazed at what I heard! It sounded like a cap gun! He told me that if you use subsonic shells it is real qiuet. The next day i went into a real tight hunting spot thatyou need to be real quiet tohunt on and filled my limit of honkers and got me a blackduck. Have anyone else heard of this thing? It works like a charm!
