What Range do you Zero the iron Sights at?

[SouthernScorp]

Just got my evo yesterday haven't had a chance to shoot it yet, but with the factory sights what range is the norm for zero with 9mm in a 7.7 barrel "pistol" evo.

25 yards ? 15 ? 17? etc


on a side note I'll prob end up swapping the factories for a set of diamondback or troy standard height "ar-15 top rail height" flip sights, these bleeped scorpion sights are much lower than I'm used to.

I sighted the factory sights in at 50 yards. But I'll probably never use them again. Now the EVO has a Burris Fastfire III on it. The factory's lower co-witness well with the Fastfire. I use the biggest aperture on the rear sight and it doesn't get in the way.

I like 25 yards. I also run a Fastfire at factory height.  With 147 subs a 25 yard zero gives me a pretty usable trajectory to 50 yards.  With 115, a 25 yard zero can make it to about 65 yards before it really starts to drop.

With an AR height sight, it would extend the range another 10-15 yards, but you'd really be lobbing them at anything past 75 yards.

I actually have mine zero'ed at 100 yards. However, I also discovered that a 100 yard zero for the Scorpion still allows for right on target up close and personal with the red dot.

I sight them in at my local gun range?  Does it matter if they are sighted in at a different gun range?

50 yards.

I sighted in at 25 but my irons still seem dead on at 50 too.

For those with something like a microdot (Aimpoint, Holosun, etc), is it desirable to have that zeroed at one range, like 100 yards, and iron sights at let's say 50?  No co-witnessing, the iron sights visible under the elevated microdot...

According to the ballistic calculator on gundata.org: 25 yard zero assuming a 2" height over bore and a 50 fps velocity boost from the longer barrel.

25 yards. Here's why.

Eta: nice screen name, op.

I've only shot at 50 yards with the pistol and carbine. With both I need to hold a 6 o'clock sight picture to hit dead center of a 3" plate. This is with the front sight bottomed out.

Currently my range goes to 75 yards, but I haven't had the chance to shoot that far since I'm in the process of extending out to 100 yards. It's a pain in the butt to cut down trees, work around stumps and rebuild the berm

been raining since yesterday non friggin stop on me so I can't go out back to the range but I did get to shoot some saturday until my uncle and his fiance stopped in for a suprised visit... then it got too dark  ... FROM THE FACTORY my evo is apparently zero'd dead accurate at 50 yards using winchester white box 115grn that I tested.. I was pleasantly suprised 9mm carbines can be this accurate about silver dollar groups using a front bag and iron sights on smallest aperature... THE ONLY thing I don't like is the sight height, I can use them fine I just am use to ar-15 height sights so I find myself bending my neck/head down after shouldering to get the correct sight picture

[SouthernScorp]

  ^^^^ see above ^^^^ excuse to justify another micro red dot sight

[armoredman]

Rain is a problem....? 

[armoredman]

No problem, I have a lot of Natural Gear t-shirts, short and long sleeve, had a pair of pants but they went somewhere. Wish Walmart still carried the discounted stuff like they used to - have a Natural gear zip up light jacket I've been wearing for about 15 years now. I would love a complete BDU style set, as the pattern works well here in the upper desert.
