Mounted on an M10 762, when I try to zero, I can't hit a 16x10 paper target at 50 yards. Is that uncommon?
1606616
In my opinion, yes. Mine took 3 shots to get zeroed and haven't had any problems holding zero. Maybe the sight or riser is loose??
1606617
I haven't taken mine to the range yet. I'm actually headed there today. I would suggest that you unmount it put it back on and try to re zero.

Optics should be mounted using the side rail left of the trigger guard not the foreend and I would bore sight or zero closer initially to make sure I'm on paper.

Not really, but it's difficult to say if it is the shooter, the gun, or the sight when it comes to accuracy. It could be that the mount on the rifle is off just enough to throw it off, could be the rifle itself being inaccurate, could be the shooter being inaccurate (no offense), or could be the sight. If you can try another sight, might help narrow down the problem.

Try this: shoot at a dirt burm if possible. Watch where the dirt kicks up when you shoot. Make rough adjustment to tune the point of impact the roughly where you are aiming.Now shoot at a paper target and hopefully you will at least be on the paper. Fine tune as needed. This can all be accomplished with minimal shots.

The riser on this model is 1" I typically use a .8 or .75. This is set for what is called a 1/3 co-witness. If you could use a lazer chamber bore sight. it may help. What I am saying is the mount is a bit tall. This might be the issue. I will say that I have mounted probably 30 of these units and I have never had a bad unit, I have had bad mounts.

Yes that is uncommon. I believe the scope is 3 MOA,( 3minutes of angle. ) This means when the red dot is put on target at 100 yards you should be within 3 inches of where you aimed.

I would fire at 100 yards, Michael. But I have been bore sighting my firearms for years and I have had good success. Try it at at 50, see where you hit, then move accordingly. Happy shooting!

There is some truth to this. The sight you mount to this rail may not be perfectly aligned with the centerline of the barrel once the rifle is rotated. This means that the center of the sight will be to the left or the right of the centerline of the barrel. When you zero the sight make sure that you take this offset into account. For example, if the sight is mounted .5" to the left of the bore center, then make sure that the point of aim (dot) is also .5" to the left of the actual target impact point. If you don't do this, your horizontal zero will be valid for only the distance at which you set the zero since your point of aim will not be parallel to the bore. There is some truth to this.

Yeah, I use 10x, too, for zero ... since I'm not a real 'professional' shooter I use trial & error plus drop info online for the loads I use at 50 meter increments for the first two BDC lines/dots then at 100 meters each for the rest ... once I know where the bullet goes it's easy to correlate actual performance to the BDC indicator. My method may not be the smart/smartest way to make the marks useful but it works for me.

I would zero at 25 and then tweak at 50. This a good scope for 50 to 100 yards. I also have the P-223 3-9X40 for longer distances. I've read good things about the P-223, but haven't had much time to use them yet.

yes , my son and i took it out to 250 with it being right on. we zeroed it at 100 and it was perfect. didnt shoot any farther though

Yes, but if you have a small error at 25 yards it will br agnified down range. Inothrwards if yay off center by 1/4" at 25 yards, you might not even hit the paper at 100 yards. I try to shoot close first, the sero in at 100 or 200 to get a trough zero. Once I have that bracket, I can scheck 25 yards, which shoul be dead on for left and right, and typically a little high at 25 yards.

If you go to Nikon's website, they will be able to tell you how to adjust your zero based on the yardage, the rifle, and the specific ammunition you are using. The website is great. http://spoton.nikonsportoptics.com/spoton/spoton.html

Sorry TU I don't know but my rifle is a Remington 700 .270 and it worked like a charm. I ended up a click away from zero at 100 yards.

The laser is fine with excellent range. The problem I'm having is with it staying zeroed. I broke the screw for the mount in an attempt to keep the X400 from coming loose when I shoot. Surefire replaced it for free but it is still annoying.

I have mine mounted on an M&P10; (308). The recoil seems to give the firedot a little problem as mine blinks out occasionally and needs to be turned on again? I have mounted it on my AR15 platform with no problems. It might just be my scope and it may be a defect. However the scope has great optics.

I don't have experience with the others, but I can see the holes in my target at 100 yds easily. It also holds a good zero, and I am getting 1/2 to 1" groups with my 24" heavy barreled AR at 100 yds.

For the BDC reticles to work properly, the scope needs to be zeroed at 100 yds. That being said, experimentation on your own at different distances may provide other workable solutions.

I have shot out to 600 yards with my 6.5 x 284 and do not see change in point of impact with magnification change with this scope- downside is, cross hairs too thick. Gary

With an air rifle just set up a target about 15 yards away and mount the rifle in a vice. Fire 3 rounds then set your scope on the center of the pattern. Save money and not buy this bore sighter. I found this bore sighter to be a cheap Chinese knockoff and of the poorest quality..

Mine will not hold a zero after 10 rounds in my M-44 Mosin Nagant. I will try loc-tite but have little hope of success.The scope does not appear to be moving at all and yet the point of impact moves several inches after every shot.The scope may be broken at this point.

Using reflective target it states up to 100 yards but I have not tried that distance the farthest I have tried is 50 yards and saw it fine no issues in bright daylight
