Merry Christmas everyone! I just installed a new generation CASM 4 point M14 scope mount on my USN MK14 Mod 0 type SEI. M14.ca It replaced my EBR rings & the color matches up with my FDE Leupold Mark 4. The Leupold is riding in a set of low wire EDM rings from SEI. The CASM eliminates the rear sight... this particular EBR stocks cheek riser never went low enough and this made it virtually impossible to access the otherwise excellent iron sights... an Insight mRDS with a 3.5 MOA reticle is mounted offset and in front of the 3.5-10x40 optic. I am currently fine tuning the position of the optic and cheek riser for best results and plan to take it for a spin later this week, but I will need to do it again once I've replaced the butt stock.
