OK I am a newbie to AR's or battle rifles for that matter. I just purchased a DPMS AP4 and have a quick question. I have read all kinds of methods for zeroing Colt rifles with detach carry handles and the markings are different from what my flat top carry handle has on the elevation knob. Can you quick run me through your recommended 25meter battle zero. I am still getting the feel for the trigger, weight, handguards, adjustable LOP, sight picture, but really want to be able to understand and set up my rifle. Do your rifles come with any instruction manual?
P.S. I love this rifle-300rds and not even a hickup!
