After speaking with Trijicon, I was recommended the Trijicon AC12043 mount which will fit my thermal after requesting an eye shutter that was 1.5" longer than stock.  Does anyone have this mount that can confirm how much eye relief is changed with it versus a normal mount?  Any concerns with the weight of a Trijicon IR Hunter Mark3-60mm?

Or, does Larue or someone else make a cantilever mount that might be better for my application?  While my ACOG runs well on my SR-15, it would be nice to move it slightly to the rear so, I might also want one for my non-thermal rifle too depending on how it works with my thermal.

TIA,
Sid

The La Rue RCO mount brings an ACOG all the way back

Larue RCO Mount is great for that


Trijicon makes a newish cantilever style thumbscrew mount too
