I made a couple of slight modifications to the mount yesterday. The mount itself is only attached with one screw, and it is towards the rear-most area of the mount, and it is supported in the middle by the raised portion of the iron sight base on the gun. However, the front half of the mount is just hanging out there--unsupported. While it is not likely, I felt that a hard whack to the top of the sight (like say if the rifle were dropped optic-first) might cause the mount to break, due to the leverage. So I mitigated it with a 12 cent plastic vehicle interior push-fastener. I drilled a small hole in the mount, trimmed the fastener to length, and then slowly filed the 'button' of the fastener so that when the mount is attached with the screw, the button touches the top of the receiver. Now any bump/whack to the red dot will be fully supported towards the front of the mount.
Also, the screws that come with the RMR are probably sufficient for attaching the RMR to the mount, but they aren't long enough to extend all the way through the mount--i.e., there's still some threads in the mount not being engaged. The mount comes with extended screws--which are actually too long. So I shortened the screws a couple of threads, chased the threads to clean them up, and now the mounting screws utilize all of the available thread. It probably increased the thread engagement by a solid 80%.
I've shot maybe four practice sessions with the gun in this configuration now, and I absolutely love it. I have a couple of local matches coming up, and the USPSA pistol caliber carbine nationals in late June, and I can't wait!
