Most people have the same complaint about low and left. Mine did the same thing. I corrected the left by moving rear sight. As far as the low I have to aim about 10-12 Inches above target from 20-25 Yards. 20 Feet away I can go to POA and put 10 Rnds through a target a little bigger than a golfball using rapid fire. I figure if I am more than 20 feet away hopefully the noise will scare 'em!
