Thanks for the opinions and replies. The last thing I want to do infringe on anyones patent. I am selling this thing to help out an old man who needs the money bad. Same story a lot of people are in right now. Hell, the old guy who made this TRIDENT, is so frail, that I would be surprised if he will be able to make any more????? Bottom line is, I love Saiga 12's, and when I saw what this guy made, I wanted to help him make a little cash. I really do not think he would be a CHAOS threat?
