I've got a stamped receiver Arsenal SLR-106U 5.56 AK that I totally love. Part of me is getting the itch for a 7.62 AK. Are milled receivers really worth it? I read somewhere that the actual new military Russian AKs are stamped? I do really like the light weigh of my stamped receiver. But was thinking the extra weight of milled might be an advantage with the additional recoil of a 7.62. Thoughts, Comments?
