A while back, John at USO sent me the original PSR Submission Scope from US Optics to have a look at. This video is just a quick look, focusing in the new Illumination USO is moving too, which is a nice upgrade to the old style.
Not a lot of details, just a bit of fun with it and our Accuracy International 300WM.
Scope is a 5-25X by 56, surprisingly light for as long as it is. Mil / Mil with a zero stop, Gen 2 XR reticle, it was really fun to play with.
it was a short trip, but definitely looking forward to the production models.
