I'm in CT and will be getting a "Compliant" model 15-22 in the near future. Like most people I'm making my accessory list already before I even know when the gun will be coming ha. My question is that I want to swap butt stocks but need to keep it fixed. Can I use any butt stock or are some made to only work with aftermarket tubes and be collapsible? I'd love some help with choices. I was thinking a Magpul CTR with the cheek riser or CAA CBS with the detachable cheek riser. I'm a smaller guy so I usually need a cheek pad to get a good weld for my scope. Help is appreciated. Thanks!
