nevermind, I just saw your earlier post. thats a great deal. I jut called my gun store and they had the regular 30mm ring PEPR mount for 98.95, and the one with the quick detach attachment for 120.
Thats a good picture. I also struggle with crimping. I never really get it right so I always just keep it as minimal as possible and can tell no difference in the rounds I have crimped and ones I haven't.
