Not sure if this is old news but Ruger is coming out with the Ruger Precision Rimfire which is based on similar ergos as their centerfire RPR. Retail will be about $529. It'll have a clamp type barrel for easy install/removal, will use 10/22 mags, a 30moa base for shooting out to 300 yards, and an adj trigger (I think between 2-5 lbs).
