I tried to set my battle zero today at the range and had some problems. I set up at 50yrds and cracked 3 off with the factory sight setting. I barely hit paper. Had to adjust windage ALLL the way left to get close to center. It still is a good 4" off center. Talked to Oly abd they said send it in and they'll take care of it. Still curious though how high above center should I be hitting. I'm not used to the peep sight but as far as I can tell i'm sighting properly but I'm atleast 3" above center. I doubt I should still be that high. My grouping pretty much sucked but thats probably partly my shooting and using PMP ammo which I know isn't exactly all that great. Another problem i had was trying to put a scope on. I have an inexpensive handle mount, maybe the problem? But neither scope I tried to mount had enough adjustment in any direction to come close to being sighted in. Would this be bad carry handle or mount or both? Or am I using the wrong type of mount? Would a scout mount be the one i need? I tried a bushnell holosight and an old simmons red dot. All in all I'm not very impressed in the performance of the rifle. Had a friend give it a try again with disappointing results. we were shooting on a bench without a real rest. Any advice?

Seems like all companies have this problem every now and then.  It is easily fixed by any manufacturer.

Send it back to Oly and have them make it right.  Then shoot it some more and make your decision.
