View Full Version : POF/DPMS .308 rifle Problem.

02-24-2008, 7:27 PM

I took my POF/DPMS TAC-20 in .308 to Angeles Ranges today and it shot great, no FTF's, BUT as long as the targets were 200 plus yards, it was dead on. I was hitting the gongs out to 600 yards, BUT SOMETHING WAS WRONG.
At 200 yards using EITHER 147 Australian F4 ball or my 168 grain BTHP Match rounds, it was 13'' inches above point of aim. The stats were as follows, the target, a score keeper 100yard smallbore rifle target. Six o'clock hold, 12''inch diameter, 8'' inch black zone. With the rear sight spun all the way down, below the 600/300 yard mark and the front sight up to the point where you could see the bottom of the front sight above the gas block, it was still 13'' high. If I did a 6 o'clock hold on the gongs, I could hit EVERYONE from 200-600 yards, with the sights adjusted as stated earlier. I am at a loss.
The only thing that I can think of, is that on all of my other AR builds, the rear sight (A2), the piece that holds the apertures (sight base), the top of it sits flush with the carryhandle when the sight is in its lowest position. It is different with the .308 when the sight is in its lowest position, the sight base protrudes .093 inches above the carryhandle. Any and all suggestions are welcome. Thanks, all Calgunners, USMCM16A2

Try starting ~2" high at 25yds, see where you're at further out.

Thanks for input, I did set up the target stand at 25 yards, and was about 6 inches high at that distance, the front post was adjusted very high. Thanks, USMCM16A2
