I know the SBR is easy, I've got an AR I form 1'd. But I'm wanting something a can holster and carry as a sidearm for silent squirrel shooting while I'm hunting. You can't carry a 22 rifle along with your deer hunting equipment, but I could carry a suppressed 22 pistol and shoot squirrels while I'm waiting for a deer. I want a single shot or bolt action so there's no action noise, and I want it to fit in nothing bigger than a drop leg holster. The only other thing I can come up with is to weight down my 22/45 bolt to the point that its too heavy to cycle.
