Took the AR to the range today (3 hours) for some more break-in and to site it in. (Just got my front site tool.) I have a FF 16" barrel with A2 front site and Troy rear BUIS. Was shooting Q3131 (new stuff) at 50 yds. After playing with the elevation / windage adjustments I can keep everything in the 8 ring with very few flyers, but they are all over the place. This is frusterating because my Sub2000 9mm will destroy a new foam target board every time because everything will stay inside the 9 ring and leaves a much larger hole. The Sub2000 also seems to have more recoil, and I have never even adjusted the cheapo factory sites.

BTW, I was using the large aperture and using my elbow as a rest. The large one seems HUGE though, but the small on the Troy is same plane, however shifted to the right. Should I bring it in to 25 yds? where should the POI be at that range in relation to 50 yds? I plan to toss an EOTech on there but would first like to master the irons. Just wanted to see what some of you thought and how I stand up to the rest.

8 ring of what?  

If you have to ask if your group is good enough, the usual answer is that its not.

YOUR GROUP AINT GOOD ENOUGH UNLESS IT MEASURES .224 INCHES WIDE!!!

Somebody PLEASE tell me what this 87 thing is all about! I've seen it soo many times and I just dont know what it means.........CRAP, PLEEAASE dont bash me for this!!

Youll probably be bashed 87 times for this

If you can keep ALL your shots in the 8 ring or better at 100yds you are doing good but there is ALWAYS room for improvement

I find the Improved Battlesight Zero to be the best method for me.

Give it a try and I think you will too.

BTW: There are other methods of Zero'ing your AR15 on the Maryland AR Shooters Site if the IBZ isn't your choice.

damn.

Larger aperture will produce larger groups - but its better in low light and for 'snap shots'.

Should I bring it in to 25 yds?

Hell No!

where should the POI be at that range in relation to 50 yds?

Point of aim should equal point of impact at 50y for an optimal zero.

talk to markm

I did zero at 50 yds, but I have a Troy rear BUIS and the large aperature is HUGE. I can't imagine using it at 100 yds. I would use the small for sighting in, but it is offset to the right. (Troy should have offset the damned hole to compensate for this.) The best I could do was to keep the majority of them in the 8 ring. Guess I need more trigger time and a sandbag or something.

+87

I have to echo what Stickman said.  The 8 ring of WHAT TARGET?  An FBI-type silouhette?  An NRA 50 foot pistol target?  It makes a difference-a BIG difference.

I just spent time on the range trying to figure out whether my sights or my aim were what was causing me to be off-low and to the right.  This was with a target with a 3-inch black bullseye; I was at the edge of the bottom right quadrant of the bull.  What size is the 8 ring on your target?  That will tell you how good your aim is.

Mine...mine needs work.  Darn.  More range time!  

The 8-ring (black portion) is 6" across.
