I have DPSM LR-308 AP4...
Sight POSP3-9X42... basically a PSO-1. That sight is also good because it can be used on AK47 (but the chevrons represent different ranges). I like the range-finding scale on the left side of the scope.
We must think alike. I have the exact same rifle, 16” barrell but my optics are a Nikon 3.5-14x42. I love it but they are heavy. I wouldn’t want to hump it for 20 miles. I’ve noticed that the plastic pmags work much better with it than the metal mags from DPMS. I have the occasional stovepipe jam with the metal mags but I’ve never had a problem with the p-mags.
