Thanks for the welcome. Look forward to browsing the site, but now I need help immidiately!!! Please any body reply with a solution to a loose rear hood sight. The hood is loose and then when I run up the elevation to my 600yd setting I noticed the whole elevation is loose not just the hood but what the hood is attached to. I had a brand new that I installed today. I had to file some down on the sides so it would fit in the assembly...a little bit at a time and it is still loose. the hood is fine but the elevation is loose...I guess I took too much off. I guess I will hqave to order another one and start over. Any suggestions or something that is archived on here. Im sure I am not the only one with this issue. And can I use a rubber band to secure it during a match or is that considered and external modification? Any help please?
