I did research ACOGs on shorties and the opinions were very much mixed as expected . In the end , I was only concerned with BDC marks being off farther out and having to createremember my own hold overs . So far so good off the cheek out to 300 yards with ' 92 British surplus , which I know isn ' t saying much , but fine for most of my shooting and the ACSS reticle is just wonderful to work with through the ACOG glass . Whether it stays on this build or not once I play past 400 yards , I can ' t say . It definitely won ' t be going on anything shorter , though . <| sep |> I followed them on twitter and set up notifications to my phone . Some shows sell out instantly . I had never been to red rocks and this summer ended up going to a shitty concert just to say I had been .
