Bet you never heared that before...lol. I got my R9 out after work today for a little trigger time and noticed my POI was pretty different than last Sunday at our FT match. At the match I had to adjust it on the practice line fairly substantially to.

After making a few adjustments I noticed this:



It seemed all at once the pieces fell together over what I had been seeing at the match and on my target paper and I said hmmm... Ohhhh...aaahaaaa!

I've always had pretty good luck with the BKL's but it looks like I may need to use something diffferent. Even after I repositioned and snugged them down it started to work its way back again after a few shots.

I put 2 BKL riser blocks in the middle butted up flush against the inside of the rings.

that can easily be cured with LocTite, as Charles says, the question here is whether you REALLY need the three pieces?

The more pieces in a system, the more prone it is to failure.

Simple maths.

The med mounts don't clear the objective and I had some riser mounts

I was just considering a tall one piece unit but BKL's don't have enough clearence for the turret box on my Simmons scope. I suppose I could shim the rings but I'd prefer not to do that.

consider milling / filing a recess in the mounts for the scope turret box / saddle.

It usually needs very little material removal and it would be a better solution with the bore closer to the LOS.

Just a humble suggestion.
