2A was "political" when it was first adopted.
UPDATED: A Novice's AR-15 sighting problem
I recenty got an AR-15 on the principle that I know nothing about them and figured it's about time I learned. After all, it's been around for like 60 years and I've been around for almost seventy, and it was about time we met.
DPMS Flattop Panther in .223/5.56.
Sixteen inch barrel.
Stock front sight.
CAA rear sight flip-over peep. (I can't find this sight on their site.)
Sight radius 14 7/8 inches, call it 15 inches.
XM 193 ammunition.
Long story short, I took it to the indoor 25-yard range and found that even with the Battle Sight cranked down to its lowest, and the front sight set so far up that it's loose, I could not bring the point of impact (POI) to the desired 1 inch or so below point of aim (POA).
Present groups, even with the loose front sight, are about 3" above where I want them.
(I had figured about 1" below point of impact would get me about 1 1/2 inches high at 100 yards, which is how I sight all my centerfires, and yes, I read about the "8/3" and "6/3" settings for the two flipover peeps, but for now, I just wanted it about 1 1/2 inches high for 100 yards.)
So, I figure I need either at least another 0.050" more on the front sight post, or, to somehow lower the rear sight that amount below its lowest setting.
QUESTION 1: Are the CAA rear sight and the DPMS rifle itself simply incompatible?
QUESTION 2. Are higher front sight posts available? Or, alternatively, is there a trick to lowering the rear sight the required extra 0.050"?
Pic shows the general configuration --nothing out of the ordinary.
