Finally got these rifles to the range. Both rifles functioned well and I was able to load using a charger. Recoil was much less than what I had imagined. At 100 yards out of twenty shots I only hit the target once. Most guys there were using scopes. No key-holing. I'm a newbie. On the No. 4, I wonder whether I should of used the flip-up sight rather than the battle sight. I made no attempt to zero it.
