Since we are talking about Field target (I think, aernt we?), the collar only covers the ranges for the game (10-55 yards), so the collar only covers that portion. sO you dont need skyscraper rings.
Lemme look for a pic....
Edit: I cnat find, nor is google any help, the ones I ve seen. You can lso use tape and just mark the yardages, but you need to tip the gun over to read it (unless you are clever about where you put the indicator). the ones I did see do go all way round. And I remember seeing some one make a collar out of very thin clear plastic that just folds under the scope as it goes round. 8inch collar ont aht bad boy IIRC.....
Stole this from Hersey Box Tony (where has he gone?). This one does glo all the way round. Having difficulties with generating the correct search verbage. but you get the idea.
