Will not zero on SA SOCOM II 308 with extended rails or on Trijicon's Rock River 308. Designed for machine gun who's rail is not parallel with the barrel. Optics Planet will not allow return/refund if mounted and fired. 4th time to Trijicon customer service repairs over 1 year with no resolution. Gunsmith unable to fix. Trijicon blamed me and my new rifle for the problem until on the third return they finally tested it on their Rock River 308 and it would not zero. I sent them large labelled 50 foot targets of performance not even close to zeroing. They made a new mount to fix what they call an "applications problem", but moved the thumbscrews to the right side thus jamming ejection of shells consistently and still far from zeroing. 4th return still at Trijicon for 1.5 months and they have been talking about a refund via Optics Planet for the last 2 weeks but Optics Planet has not heard of this yet. I was very excited about this scope, but it has turned into a huge was of time and energy. Where's my money?
Pros: crisp optics, quality look and feel
Cons: It will not zero in on normal rifles so it is totally useless!
