First of all I admit that I don't know much about AR's. I've shot them but that's about it. With that said, I see there's a conversion kit that you can buy to convert an AR to a .22. Do any of you have any suggestions as to which kit is "reliable"? My bro-in-law and I are looking to get one for my father-in-law for his birthday so it would be a little cheaper for him to shoot. We don't want to get too crazy in price but at the same time we don't want to get something that's cheap and jams all the time or what not. Thanks in advance for any information you can provide. I don't know if this will matter or not but I'm pretty sure his AR is a Ruger. He just recently picked it up at his local gun shop.
