Bought these and ended up being able to use the super low rings. TPS part # is 30580-030-01 low rings .925" Put these on but never fired the gun. $70 shipped I know I'm new on here, I just got back into shooting and got on here to do some reseach. Go to Archerytalk.com and look up ProtecMan (me), I have 100% feedback spread out over several years. I appreciate all the help I have received on here!
