i just put a mark 4 leupold mr/t scope on my m1a and i love it! mil dot reticle for range finding is the best. an old friend on mine that was a vietnam vet w/ MACV SOG just gave me this barett to top it off......im ready. and by the way....NO MOSQUE and GROUND ZERO! i can't think of a better battle rifle to have in my hands. i think this is the perfect scope for this weapon as well. it is mounted on a bassett machine mount and have a Turner leather sling(the only way to go IMHO)
