So I went out to the range today, first time shooting my AR15 in non-ban form.  Well to be honest I have had it for 4 years and for about a year I have had it with me in WA but jut never got around to shooting it.  But I tried to zero my TA31F and started to notice some problems.

I was using some Wolf 55 gr. ammo and fired off about 2 mags in quick succession to test my AR with the ammo to make sure it would function.  I then settled down to zero and fired the first 3 round group.  Well it was close so I figured some quick adjustments would get me in the black.  So I tried to make the adjustments, I heard the click from the ACOG and thats were I started to notice problems.  I figured that I had to go up 10 clicks, when I got to around 6 or 7 it began to get hard to turn (was using a dime) so I immediately stopped in fear of stripping out the adjustment.  So tried again and fired it moved very little.  I tried the same for windage and it too was hard to turn and seemed like it was not making adjustments easily.  So I fired a 3 shot group and the POI shifted on me, tried again and it did it again.  So I figure maybe its the ammo and try some M855, well it to was hitting low so I try to make adjustments off that, still hard and didn't want to risk stripping it out, made what little I could and fired again, still hitting low.

So now I have a problem.  When I returned home I tried again with the adjustments, moved them up and left, down and right, they moved all right with positive resistance and click noise.  I am going to try again this weekend with some federal 55 gr. ammunition and hope for the best.  What could be wrong and is a call to Trijicon in order for how to send it back for repairs?

*UPDATE*  Well it seems that it was the ammo or another issue.  Today I used my borelight kit from my squad and checked the adjustments.  Well it adjusted fine and did not have any problems.  So I guess it's back to the store to purchase some better ammo and back to the range.  Hopefully it works out.

I had a similar issue with a ta11.  Called trijicon, sent it back,  and it came back all better.  Don't now what they fixed but it worked.
