Re: Can you sight in an AR15 in 5.56 with .22lr?
.22 of is cheap. Sight it in at whatever distance you want with the .22 and then put some 556 through it and see the difference.
Talk is cheap its it gun shoot it and see what happens
Given the different ballistics of the rounds I would assume at 25 yards they would be close ish and at 100 the .22 would be pretty low
