Need help to zero scope

[Silent909]

Hey guys, I bought a Bushnell 1-4x24mm scope for my AR-15 and haven't mounted it. This is my first scope so not sure if it is the same as iron sights. So I read Bushnell directions and it stated that I need to zero at 100yds at max magnification. My problem is the closest range near me is only 50yds max and won't be going to the mountains any time soon. So can I or do I have to wait til then? Second question is how do I adjust the scope's zero to the target since my scope is a mil dot not moa. (Assuming one click moa is one box on the target/zero chart) Thanks.

Well if you are only going to be shooting at 50 yds then sight in there. Or make the drive to a real range.

I would if I had a car haha. When I go on outings, It is usually with a group of friends but we haven't been able to get together lately. So I guess I got to wait until that day comes.

That's... weird. You can zero it at whatever distance you want(well, as long as you have enough elevation for it). I'm going to assume this is because it'd a BDC reticle, if that's the case those are never really that accurate for most people anyway. Plus, you can change it later if you want.

My problem is the closest range near me is only 50yds max and won't be going to the mountains any time soon.

Ok, so zero it at 50. Or, zero it at 25. Lots of people like a 25 yard zero. Google that and learn why.

Second question is how do I adjust the scope's zero to the target since my scope is a mil dot not moa. (Assuming one click moa is one box on the target/zero chart) Thanks.

Oh god... no. You don't need a special target. I've never understood why people insist they need special targets for this. You can do it with a blank pie plate.



Don't have a rest? Use some sandbags front and rear. Don't have sandbags? Fill some socks with sand and tie them closed. If you don't have socks... can't help you there.

That Bushnell PCL has the same reticle as my 1-6.5x so it uses the BTR-1 reticle. You can zero for any distance you want but since it has a BDC, Bushnell recommends a 100y zero so it'll closely match the BDC subtensions (distance between stadia).

Assuming 55gr American Eagle at 2900fps, here's a 100yd zero with that reticle, according to Strelok:



For a 50yd zero, here's what you get:



If you want to zero for 100yd on a 50yd range, zero about 0.75 inches low. This will be very close but of course, always verify at your intended zero range.

Yea it is a BDC. Its a cheap scope to start off with thats why I picked it lol. But for sure I will be upgrading in the future. Well I asked about the target mainly concerned with how to count and adjust the scope thats not moa. Maybe I can find that on youtube.

You don't need to using the method in the video I posted. You don't need a laser, you don't need a target with a grid, you don't need a ruler, and you don't even need to know how much 1 click of scope adjustment equals at the distance you're shooting. If you do as instructed, you can get your scope zero'd in less time than that video takes to explain it.

As far as mil adjustments, 1 mil is about 3.6" at 100 yards.

1/10th of a mil is going to be about .36" at 100 yards.

1/10th of a mil is going to be about .18" at 50 yards.

Want tons of reading to do(and learn a lot in the process)?

Oh alright thanks. that gives me a better idea. I'll look into the reticle for more details.

haha yea I was looking for special items, just the measurements but thanks Ill check those links out as well.

Lots of good info here.

Actually I prefer to start at 25 yards. Sometimes after mounting, the scope will be so far off target you won’t even hit the paper at 100 yards. By starting at 25 yards, one will have a greater chance of hitting the paper.

After you have hit the paper it is a simple matter of shooting three rounds in order to get an accurate picture of where the rifle is grouping. Then make adjustments accordingly and shoot another three rounds to see how the adjustment worked. Repeat until you achieve the desired results.

Zero it by looking through your barrel at your residence (even inside) before you go to zero it out at a range. That is what I did with my Aimpoint PRO and it worked very well. The distance inside my place was less than 15 yards and I did the math and made the proper adjustments to the sights.

I'm not sure if I can link to another website but you can get targets for a 25 yard/meter zero that will get you close to a simulated 50 yard or 100 yard zero.

here is the site I am referring to: http://www.ar15.com/forums/t_3_18/32...o.html&page=15

Around the middle of the page there are links to download the targets. Basically your point of aim is at the silhouette but make your point of impact at the crosshairs. Not sure if that makes sense but when you see the targets you should understand.

Note: The targets are for performing RIBZ (Revised Battlesight Zero) with a carry handle, but I am not completely sure why it wouldn't work for zeroing scopes.

good link for those of us who want to bore site and live in an apt etc! Thanks

Hey I have that scope mounted on a middy, works good, follow the directions of 25 meters then start making adjustments after shooting at 100 yds targets.. like the scope I thought I was the only one to buy one!!! GL john

[MrSam]

They should really reword that. Sighting at 100 yards should be a suggestion, not a requirement. Sight it at 50 yards on full magnification, or whatever magnification works best for you. If you're not hitting paper, move your target to 25 yards, then when you're sighted in, do it again at 50 yards.
