What size rings can be used on the Chipmunk? Posted on March 27, 2017May 11, 2017 by Spyke Krepshaw Any rings that will attach to a 3/8″ dovetail scope mount will work. The upgraded Crickettinny rail will also accept any Picatinny style rings. by Spyke Krepshaw Are the Crickett and Chipmunk accessories/spare parts interchangeable? Will a Chipmunk with a scope fit in the padded Chipmunk gun case?
