I installed an Eagle flash hider with an HK style sight on my mini 14. It made it shoot really low. When i went to sight it in today I moved the peep as far as i could to bring the bullet up but it still shoots low. I know there are aftermarket peep sights available but i dont know if that will solve the problem. Is there anyway i can keep the original peep and zero it in? Do I need to buy a new rear sight? Any thoughts are very much appreciated!
