I have the DLOC Pulsar mount on my XP38 and XP50 plus my friends all have them on their XP38’s. Money well spent in my opinion as I move my thermal scopes around to get max use out of them no POI shift at all. The DLOC design fits all my rail mounts be it a bolt action rifle, AR15 or even 10/22 with pic rail no tools or mount adjustments ever needed.
Even my Larue lever mount on the MK III 60mm doesn’t change rifle to rifle without needing some adjustment do to varying rail sizes. If you have to adjust the nut for more or less tension on the lever when changing rifles your POI is lost or hard to get back to same tension. The DLOC screw design simply tightens down the same every rifle,/every pic rail/every time a simple design ,but it works if you change your scope to different guns a lot like me heck you have three profiles use them
Personally I love the trail scopes but that factory mount really cheap feeling/looking on a 4500-5000 dollar scope.
