Default Eo tech sight in at 50-200 or 100 yards?

Any eotech or rds users out there?
At which range do you prefer to sight them in at?

I have mbus pro flip up iron sights set to 25-300.

I like 50y since it's relatively flat out to 250y. A 100y zero is good too since some folks like to know that you're always holding over (since the drop is lower).
Also, I don't think 25/300 is a good zero for flip ups. You're going to be shooting way high most of the time. They teach the 25/300y zero in the Army because it matched to the rear drum, which you could use for elevation.

Good info,
So would you recommend my flip ups also to be 50-200?

Yes, I don't think it's a good idea to run different zeroes between red dots and irons.

That's good advise from SuperSet above, and it's a good idea to memorize that chart too.

I zero for 25 yards at the indoor range, it's quick to do so. Once I get the time and opportunity to go outdoor, I then convert to 50 yard zero.

50/200 zero, here are some handy references.

There is a approx. range quick reference card that I made for an EoTech XPS 2-2 reticle that's sized for a 3x5 index card.

You can use the 25 yard target that someone made to easily Zero an Aimpoint for a 50/200 zero. Aim at the center of the target (POA aka Point of Aim), adjust your optics to put your groups in the lower grey circle (POI aka Point of Impact). When you can get to a 50 yard range, your POA and POI should be one and the same (and also at 200 yards). You'll want to verify zero at 50, make adjustments, then check at 100 yards also and adjust accordingly.

Thanks for sharing DCNB! That's exactly what I am looking for.

Marine Core 36 yard zero is equivalent to 300 yard zero. I can give you first hand experience that with this zero, my point of aim is consistently my point of impact with very minor deviation. This is an excellent zero. I use a couple of steel plates (18" x 30" Silhouettes) every range trip and ill set them up at a variety of distances out to around 200 yards. I always hit center mass and im using an Aimpoint Micro
