I also want one of these really bad. Could you tell there was much more weight on the rifle after you added it? What kind of rifle did you put it on? I want one for my 14.5" middy.
I couldn't tell any difference whatsoever in the weight. I'm sure Pyplynr will comment on the weight of it. I mounted it on my POF P-308.
My setup is:
