Great site!!! Last time I had a black rifle was 1967 when Sam issued me one. Didn't realize how much I missed it and man have they changed. I'm a benefactor NRA member and my 1st is a RRA midlength A4 right out of the catalog. I've actually ordered a 2nd one (10 weeks) because of HR1022. Anyway, it's fitted out with an Aimpoint CompML3 4MOA, Arms 22M68 base w/full riser and ARMS 40 BUIS. Co-witness is perfect and so far it drives tacks! 1 MOA @ 100 and I suspect better w/better ammo. Love that rifle and now have BRD. I reaaly appreciate this site as it has given me a lot of useful info. Thanks guys. Hope to be a contributor and ask intelligent questions....errr or not!
