DPMS 308 AP4 Battle Zero

[Ranger175]

Hey All,
I have been "lurking" this forum for some time now and decided to join up. I have to say I have already acquired a ton of knowledge from you guys and want more lol. To my question. I just bought a DPMS 7.62 AP4 and was wondering what distance I should battle zero it for 150 grain rounds? I know with 5.56 the battle zero is at 25 yards. The projectile crosses line of sight at 25, and 300 yards. So what is it for 308? Anybody have any info?

Thanks

It's really close to the same. Zero at 25 and you will be real close at 300. The only way to get a true 300m zero is to actually zero at 300, though.

20. What range should I zero my AR10A2?

After asking this question myself I did a little research. The A2 AR10 sights are calibrated for the NATO 7.62 drops. So to use it correctly, set it on the 200 graduation and zero it in at 200 yards or 45 yards. Now you can use the sight to its full potential. You can use 45 yards since with the 20" barrel and 2700FPS NATO 147gr FMJ the round will cross at both points
