Questions Regarding Zero and EOTECH w/ Magnifier!

[Brandon B]

Hey guys,

Quick question here regarding the Eotech EXPS3-4 paired with a G33 Magnifier. I have used eotechs and aimpoints for a while now, but have never once used them with a magnifier. I usually have my 5.56 rifles zero'd at 100 yards, therefore when shooting up close I use the hold-over method. (At 25 yards, my red dot will usually be placed around 1.5" above what i want to hit, so on and so forth).
SO for my question. I recently purchased an EXPS3-4 and G33 combo. If I sight my EXPS3-4 in at 100 yards like my other red dots, does the magnifier change the POI at all? Or when I flip up the magnifier into the magnifying position, will I still be sighted in at 100 yards?

Basically my main question is does the magnifier change anything at all, or does it literally just magnify what im seeing and have no negative/adverse affects on the already zero'd red dot?

A secondary question is, if I am engaging a target out at 100 yards while magnified, and i make a quick change to a closer target (lets say 25 yards for S's and G's) while STILL MAGNIFIED will I still use a hold-over method of 1.5" above the area I want to hit, or does being magnified at a closer distance have negative/adverse affects on my hold-over?

Thanks so much for your help, this is a new concept to me and I want to get my head wrapped around it before I waste some time at the range.

I do not have an EOTech but I do use a 3X Burris magnifier with both a 1X Vortex Spitfire prism scope and a SIG Romeo 5 XDR reflex red dot tube sight. I usually sight those optics in at either 50 yards or 50 meters. I have not observed any shift in POI with the magnifier deployed or not. I swing it to the side for close range work (less than 40 yards) but I cannot imagine why the magnifier would alter the amount of hold over required, unless of course it shifted the POI dramatically.

thanks for the reply. Yes i was going for a 100yd sight in because it is both a rifle i trust for home defense and also a rifle that i run hard in the field. I engage targets from 100 yards all the way down to 7 yards with the rifle, and in my experience ive noticed my rifles zeroed at 100 yards are almost dead on from 7 to 100. im at about 1.5" hold over at 25 yards, and moving all the way down to 7 yards barely gives me any difference in hold over, maybe 2". I just have never used the eotech magnifier so i wasnt sure if it was going to cause me some sort of issue. i notice the magnifier has adjustments for up/dwn left/right, but maybe thats just to center the reticle from the red dot, not really to sight in the magnifier.
ill get out to my 100 yard range and screw around with it. until then ill have to do a 100 yard zero at a 25 yard sight in. aka aiming 1.5" higher than poi

The magnifier is literally just that, a magnify glass for your optic. It in no way affects your actual sight, it just makes easier to see. You are correct, the adjustments on the magnifier are to center the reticle in the magnifier field of view. I have never bothered to mess with it, as it's always been close enough not to care.

great!
thanks Jenrick for the response. Now this makes me less hesitant to use it. Its such a cool set up, although a little heavy.

I have an EO Tech 552 with a magnifier on a Daniel Defense 6,8. It works right well. OTOH, the 552 or its dot size limits the rifle's accuracy. If I want to shoot a running raiding raccoon, a dot is hard to beat. The magnifier adds weight same as a scope or NV.
If I want to shoot a clay bird and its pieces at 200 meters; a scope is better. IMO, there isn't a simple answer; as the best answer depends on what one needs to do. If that makes sense.

makes total sense. Yes I noticed when I took off my EXPS3-0 and added my EXPS3-4 and magnifier I noticed a great difference in weight. I’m already running a heavy rifle with the colt m4a1 socom 14.5” heavy barrel, a KAC rail, and the LMT sopMod stock. My magnifier set up is definitely not going on my carbine

One thing I've learned is unless one is only doing one thing, there is no real one rifle solution. At least that has been true for me.

does the magnifier change anything at all

The 1moa dot is now a 3moa dot and the weight is magnified.
If you take aim at 25 yards while magnified, the dot is bigger. You have not changed the sighting adjustments, only the magnification.

A 2 MOA dot of a reflex RDS (for example) looks three times bigger behind a 3X magnifier, but the dot does not become a 6 MOA dot. The target is magnified proportionately, so the dot still covers approx 2 inches of the target at 100 yards.
