I like it because I can work on them. They also have tons of options. They don't need things like glass bedding. Changing out parts is very simple. I also find I can shoot one better than a bolt gun in field posistions because of the vertical grip. The weakness they have is limited ability to accept longer cases than 223. Also the design of the gun was never around optics. Yes optics can be put on the gun but you need cantilever mounts and people want different mount heights with options being somewhat limited
