Free bump for a scope that I was pleasantly surprised by. On my 18" AR It dials and tracks great. Return to zero has been solid. The BDC lines up well for me with 55 grain FMJ, so my system is that I zero it for my 77 grain OTM load and dial corrections for that (has been solid and repeatable past 500 yards), then for 55 grain just dial my .75 minute offset for zero and use BDC from there. Great setup if you want to be able to run M193 bulk stuff plus a precision/heavier/hunting load out of the same rifle without worrying about two zero's.
If I had an AR I was looking to put a scope on I'd buy this for sure.
