OK test fired it at 50 yards and all x/10/9 area. 100 yards got weird it was hitting below or above target. I adjusted the rear sight to 100, my dad thought it was me till he shot and it did the same to him. We set target back to 50 yards and all x/10/9, had us scratching our heads. So it shoots well. I was planning in getting a Tri rail mount that I found it doesnt break or ruin the rifle it seems. It just bolts on easy peasy, and is strongly secure.
If zombies, i have gone for big guns, will return soon !
