A2 carry handle sight - windage adjustment. How much is too much?
Without getting too long winded here, bought a complete M16A4 style rifle last spring from a mfg everyone would recognize. Couldn’t get a BZO. Sent the upper back and the mfg said they adjusted the front sight which I assume was canted.
I can zero the rifle now (using a Marine style 25 yard BZ), but doing so requires me to crank the windage adjustment on the carry handle rear sight almost completely to the left (there are a couple of clicks left). The POI is on target.
Is that acceptable and in spec, in terms of quality that someone should expect for a AR-15? Am I being too picky? If it zeros, just be happy and shoot it?
