RE: Problem,help me....
That tab is made of pretty heavy steel, how did you break it? Could it just be bent? I did that onceyanking the string up and over top of it, between it and the scope rail, ended up with a metal "slap" when I shot.
If it is indeed broken, it can be replaced, it is screwed down under there, but the whole scope rail has to come apart to access the screws. It's official name is the "arrow tension holder down thingy". It does have an important job so make sure you get it right.
Can you post another photo of the damage?
