I have read brief notes on a "blow off valve" on the side of the valve to regulate the 2200 for Canada.Does that require a valve replacement?Will that affect the collector value of the rifle if replaced?
In my nosin' around the web I had seen pics of the Canadian valve.There was a chamber added to the bottom of the valve body connected thru a port and sealed with an O-ring.Looked like a module on the ISS......It is actually on this forum somewhere, but be darned if I can find it now..........
