I am new to using scopes, I've mostly just shot using Iron Sights, and the few that I have shot with scopes, they weren't mine so I didn't do any of the setup, and I am getting ready to drop a Trijicon 4x ACOG sight on my Bushmaster Carbon-15 M4, but I have no idea what to do in order to zero it in and make sure its setup right and is accurate. So if someone could help me out and explain the process to me, or give me some links to some type of guide or other material on how to do this, that would be much appreciated it.

Re: Zeroing Scopes and other Optics
Follow the instruction manual that comes with the scope. If you don't have it, you can download it from the Trijicon website. It's not all that different from zeroing iron sights. You're still adjusting windage and elevation.
As a couple tips though, when you mount it make sure you push the scope forward on the rifle towards the muzzle ensuring contact of the recoil lug against the cross section of the rail before tightening it down. Boresight your scope by removing the upper and bolt carrier, looking down and lining up the bore on a visible known object like a fence post or such, then adjusting the aiming point onto that object too. This will make sure you're at least on paper when you go to shoot and zero.

Re: Zeroing Scopes and other Optics
Word, thanks for the help, I actually just learned out to boresight the other day from watching a YouTube video from FPSRussia (if you haven't watched his videos you should, not only is he hella funny, but he's a great shooter and has lots of cool toys (not all of em are his, but most are) and he gives a lot of good info. And then I also read the manual on my Leupuld Scope, and got my scope zeroed in pretty good. MY buddy is coming home on leave pretty soon and hes a scout sniper in the marines and so we are gonna go shooting a lot while hes home and hes gonna teach me a bunch of stuff, as well as zeroing in my Iron Sights, cause I didn't really know how to do that either until reading about it. I've owned guns for awhile, but never anything with a scope, and I just now am getting into precision shooting and wanting to start doing Long Range Precision shooting competitions, tho I dont just wanna do Long Range stuff, I wanna do like 3-Gun style competitions and run n' gun, clay shooting, etc etc. I wanna do it all hahaha.
Anyways, again, thanks for the advice.
HAVE NICE DAY ! lol (watch FPSRussia and you will get that joke)

Is it a 223 your zeroing in?

Re: Zeroing Scopes and other Optics
Another thing you should remember when mounting a scope is to keep it level.
I like to use a plumb line hanging from the door frame in my house and make sure the vertical line of the cross hairs line up with plumb line. Do make sure your plumbline is not moving.

Re: Zeroing Scopes and other Optics
Yes making sure its level makes a big difference, you may have to start about 25 or 30 yrds to make sure your on paper then move back

Your buddy will be able to get squared away. Eye relief and natural point of aim will be something you will want to read up on prior to mounting your scope. And + 1 on leveling the scope/reticle.
When you shoulder the rifle you want to have proper eye relief and able to have full view through the optic. You don't want to have to break your cheek weld on the rifle to have a clear view. Improper eye relief will make you feel like your are fighting the rifle. Good luck.

Re: Zeroing Scopes and other Optics
A better term is to make sure you keep your vertical stadia is in axial alignment with the bore of your rifle.
Level has nothing to do with the alignment of the vertical cross hair of the scope and the bore of a rifle.
Level has to do with gravity and the parallel alignment of one surface of an object to the face of the earth (given that the face of the earth is not flat).
Imagine if you will, a perfectly flat plane and a baLL bearing.
Given: there is no friction between the flat plane and the ball bearing.
Given: there are no outside factors affecting the inertia at rest of the ball bearing.
IF: the flat plane is LEVEL in all directions
THEN: the ball bearing will not move from its position
ELSE: the ball bearing will move to the low side direction of the flat plane if it is not level because of the effect of gravity upon it.
No that is LEVEL . . .
It seems to me that many shooters are using the horizontal stadia to true in the scope to the bore of the rifle; this is inaccurate. It is the vertical stadia that effects the lateral alignment/bullet impact of the rifle.
Now, given that the vertical and horizontal stadia are in exact perpendicular alignment, the use of feeler gauges can be accepted as true and accurate IF the base of the scope is flat and perfectly parallet to the horizontal stadia of the scope.
I know, I'm being pedantic, but such is life . . .
