Whats your Red Dot Zero? 25-50-100 yrds?

[45r]

I have my TA31F dialed in with a 50 yard zero. So far I've tested the BDC and it works well. I know everything inside the chevron is GTG at 200-250 yards. For a 400 yard shot I do have to place the object between the 4 and 5 hash marks.

all my red dots are sighted in at 50 yds, and i can pretty easily (shooting off a bench)make hits on 8" steel gongs by holding in the center at 100 and 200, then at the top of the gong at 300. and i'm not even that good a shot.
i'm not going to shoot a carbine much farther than 300 with a red dot.

My Aimpoints, EoTechs and others are sighted in at 50 yards. I can't see real clearly much past that and it seems to be a decent defensive range for me. Besides, a 50 yard zero gives me decent shot making ability to about 200 or 250 yards.

My Aimpoint is currently zero'd in at 50m. I'm happy with it at this range

What kind of data did you use to get such different results than Derek?

I prefer the 100yd zero for LE purposes inside of 200yds. The 100yds zero has a flatter trajectory out to 200yds than the 50.

How do you figure? A 50 yard zero has you within plus or minus 2 inches of your zero out to 200 yards. Most times, well inside that number. A 100 yard zero is at roughly 2.2-2.8 inches below your zero line at 200, depending on which velocity & bullet weight values you want to use.

Did you maybe mean to say "flatter out to 100 yards"? Because I would certainly agree with that.

Normally if the RDS is the primary optic and placed in a mount that affords a lower 1/3 co-witness or an absolute co-witness and therefore has a nominal height over bore I would say 50m, set it and forget it.

However this is a "back-up" RDS mounted above an ACOG with an ungodly height over bore. In practice this optic should be used at distances no greater than 20 meters for extremely close shots, after which you should be "dropping into" the main optic for the shot.

I think the OP did right sighting the optic in for 25 meters.

I zero'd mine at 50 yards. I think this is the sweet spot for non magnified optics.
