I made it to my favorite gun store today. I got the lower for my 22lr upper I got a little while back. I was swapping it with my 5.56, but am glad to have it on its own now. The 22 is great as it's actually cheap enough that you can target practice with it! The scope I had gotten for it didn't fit on it, so still have to work on that, but almost have it set up now. I didn't realize there were so many different sizes of scope mounts. The more I learn about firearms, the more I realize I don't know. Anyways, the goal here is to have a 22cal AR rifle that I can play with. Almost there!
