Rimfire winner - Rock River Arms Two Stage Match AR-15/AR-10 Trigger Kit

Have 17hmr rimfire upper that doesn't work with notched triggers - insists on single stage mil spec. That doesn't rock my boat, so I replaced my Aero 2 stage with this one - not only the 17hmr bolt slides over it with no problem, but this one is actually a better trigger than what I had in (which was outstanding already). So now, got another one for my other hand :) (AR15). Pretty happy with this purchase so far
