I've got a Ruger American in 6.5 Grendel (AR mags) that I would very much like to replace the mediocre-to-bad factory stock on, but, alas, the Magpul Hunter stock has no good magazine options for 6.5 Grendel. I am considering the MDT LSS-XL Gen2 "AR mag" version - does anyone have any experience with that version? My primary concerns are magazine compatibility and feeding reliability. I know it's new, but was hoping someone was running it by now.
