I just received my Strikefire, and it all went together great. But when I was pushing on the rear lens cap I felt the whole thing shift forward a little. After making sure I screwed the optic down tight enough, I checked the mount's attachment to the rail, and it does slide forward and backward a little bit on the rail. I tried turning over the moveable part that the screw cinches down, and that didn't help. It's not like it's completely wobbly in there, but like i said, if I put enough pressure on the rear lens cap to close it, the mount will shift forward. I don't have a torque wrench, but I do have the thing screwed on pretty tight (till my fingers hurt). Do I need to go ahead and use a socket and tighten it a bit more? Should I try some sort of wedge or shim to tighten it up? Am I doing something wrong? This is my first optic install.
Here are two pictures that give you an idea of how much shift there is, and one picture of the bottom of the mount, just incase there's anything abnormal about it. Sorry if the image quality isn't great. Thanks for any help.
