My friend and I took his AR to the range today yet again. I sighted in his primary arms pac3x scope that is brand new practically(3rd time using it). Got it sighted in at 25 yards. Shoots absolutely perfect no problems what so ever. Moved target to 50 yards, shot at center bullseye expecting a little bullet drop, the hole was 4 inches above the bullseye. It didn't make any sense to either of us. We put 10 rounds down range with all the same result. All above the bullseye. Moved the target back to 25 yards, shot dead on. At 50 yards, I had it absolutely perfect line straight above the bullseye but a centimeter here and there between bullets trying to figure out what was wrong. We are still clueless about the whole situation. Didn't know if it was a defective scope or what. He is checking into it tonight. Any ideas? Picture @ 25 yards zeroing in, 30 rnds.
