building a 16" 308 with Rainer ultra match stainless barrel, JP bcg, free floated PRI tube, etc... I have a MAMS on my 556 and love it - the product not the price. My question is - Does any one know if the 7.62 MAMS will negatively effect accuracy out past 100 yards? might seem like a stupid question but most brakes I see on AR-308s are more "open" like the PRI type breaks.
