Kalinka introduces Version 3 of the Tim Heffron mount

This is a 30mm ring mount is probably the best opition over the other two version that have been out there. When the discussion of a side mount that would co-witness was wanted, this was the one referenced in the first place. Apparently Tim finally got them to import it! It should co-witness with a lot of rifles and allows a little more mounting options with the rail. Looks like you could even use offset rings that are currently being used for flashlights.

Report of Kalinka's co-witness Aimpoint mount breaking

In January, Kalinka Optics http://www.kalinkaoptics.com/ released a special run of side rail mounts that would allow co-witness with a Aimpoint M3 style optic. I have one of these mounts and also a similar mount they offered that usually is for the PK23 which I and others modified to work better as a co-witness mount (see this thread: http://warriortalk.com/showthread.php?t=60011).

Apparently one of these broke already in it's thin point where the ring attaches. http://www.ar15.com/forums/topic.html?b=4&f=56&t=124897&page=5 That's too bad if it is a problem with all of these mounts since they are my favorite right now. I'll fall back to the BP-02 if these continue to break.
