I can't find the thread about AR's and lowers but i was tlking about iron sights not needed below 300 yards. I was sitting on the porch enjoying the sun. It is about 140 yards or a little less to end of driveway. nieghbor's fence post start at about 210 yards. I don't hink I would shoot at a deer with iron sights now, in good light, beyond 260 yards with a good hold and rifle sighted in at 250 yards. Hard to believe time has caught up with me but it appears so. Time was I could shoot a rabbit at that 250 to 26 yards after years of shooting but I would be doing good to see it now. Out west 300 yards ppears as just a stone throw away. Shooting something like a buffalo at 400 yards with practice and faamiliar rifle would not bee too much trouble for young guys. Better get out there and practice and enjoy youth it all goes before you know it.
