My wife and I are looking for a rifle for this Christmas (yes, I'm lucky). I like the flexibility to change from the .22lr to a .223 upper down the road. It's $450 at CTD. What has everyone heard about this gun? I can only find info on the 22 uppers, not the entire firearm. It seems like it will be a fun starter rifle. Plus it has upgradability, due to the AR platform. So what are your thoughts?
