Hello Goldtip;

I have had an Overkill release for over 20 years now,and it works as good today as it did new.It will go to my grand kid when I die.Because I will never wear it out.
As for as the loop thing,not sure? It does have small calipers so you can have a small loop.

There's a guy on Archery Talk called Extreme 3-D that sells them.When I bought mine,I only paid 100. for it,and its the deluxe model.That was a lot of money for a release 20 years ago.The guy in Vegas, at the shot show where I bought it said I would never wear it out and he was right.I shot compition withit for 18 years and now use it for hunting and have switched to a Carter Chocolate Addiction for competeing.
