We have accumulated a descent amount of Kolar T/C and T/S adjustable ribs (only ribs in this post). We have #1’s, #2’s and the real high shooting #3 ribs. Available in wide and tapered rib width. A real cheap way to dial in your Kolar to shoot where you’re looking..Asking $125.00 each plus s/h. Shoot well!!
Kolar didn’t mark their ribs. Everything that we ever received had a #1 standard rib, unless specified differently. I have some measurements you can use as a guide. A= muzzle end of rib B= center of rib, length of slot at middle bead C= rib at the chamber #1 Rib. A= 1.03 B= 1.23”. C= 1.27” total differential front to back. .24” #2 Rib. A= 0.80 B= 1.07”. C= 1.17”. total diff .37” #3 Rib. A= 0.85 . B= 1.16”. C= 1.35”. total diff .50” It’s hard to tell the back of the rib height without removing, see where you’re at in the middle slot and the end and we’ll go from there. I hope this works! Doug
