I think just to be sure, I would call GMB Co and ask them the measurements of their dove tail. Also they could probably tell you. I looked at mine but without removing them and trying them, I could not tell you.
Yea Catuga just by looking at it its really hard too tell, I have a TC fiber optic I was thinking about putting in but really don'i want too drift the other out if I really dont know, Ill call them thanks John
