Acog :2 eyes open

[SDBlaster]

I have been trying to learn to use the acog w 2 open eyes for close distance and sometimes it is on, and sometimes it's an inch left of the intended aim point. Anyone with more experience have any tips ?

[jgstorm]

When I learned I was told to keep both eyes open and with one hand cover the exit of the ACOG. When you line up an object move your hand away and see just how close you are. After a little time I found it was easier for my eyes to relax and now I do it without a problem.

Thanks I'll give it a shot, are they ,meant to be used w two eyes open for close range, and can you remove them once zeroed from the platform and remount in the same spot while maintaining a zero?

They are meant to be used with either 1 eye open or both eyes, at any range. The zero should be "close" after you take it off and put it back on, but it might be off by a couple MOA, always best to double check.

Are you talking about shooting occluded? If yes, your POI is always going to be different than your POA because your dominant eye isn't looking through the optic.

I've never been able to go both eyes open with the acog. The magnification throws poi off quite a bit for me. Still minute of BG, but too much for my comfort. Can you do it? Certainly.

"They" say that the zero will hold, but I think it's impossible to remove any optic, put it back, and have 100% repeatable zero. Will it land close enough? Probably, especially if you use a torque wrench.

I'm biased to the acog though, I can not get proper eye relief with it. Maybe my eyes are messed up, I don't know. I always have shadow one way or another. The eye relief is also too short for my taste, always getting scope bite (usually just a light tap), or a charging handle to the face. It's not a bad optic by any means though. Great glass, durability, reticle is pretty good, size/weight... it works, just not my preference.

Yea I am having problem going 2 eyes open. It's always a little to the left of the point of aim unless I bring the rifle straight up into my sight picture. It's close but .....

It takes getting used to binocular targeting BAC style.
Focus on the target then bring your rifle up to impose the reticle on it and focus on that.
It's really that easy. Long or short range works the same.
If you're having problems after about 500 rds then you may have bought the wrong sight for your needs.
I use a ta11 and ta33's as well as an Aimpiont M4.

I find doing anything close with my ACOG produces a blurry image. Once I extend out past 30 yards or so, it is crystal clear with both eyes open. A true red dot is probably the best bet for short self defense range type of work and I feel like the ACOG is designed to shine at 50 yards plus.

Idk about you normal people but its very easy to me to aim with both eyes open with any sights, including iron sights. But thats because my left eye is a "lazy eye" and im able to control it.
And when I turn my lazy eye on, its easy to focus on whichever eye I choose and ofc I choose my right eye.

[fritztkatt]

Iron sights or a red dot is easy to use for me. There isn't the parallax error from magnification. It takes just a tiny bit of focus and the images overlay just right. OP, have you considered your usage of the rifle/optic? I understand the desire/need to train for closeup work when you're stuck with a magnified optic, but are you trying to dedicate a magnified optic to a cq use? That would just be limiting your effectiveness.

I certainly understand if you're doing this because you're broke, like I am, and you have to use what you got. Look up some articles by professionals, and go shoot. I'm certain you can train yourself to use a 20X optic at 10 yards if you try, although I recommend just getting a red dot.

I have an eotech w a 3x flip to side mag and they are awesome combo. I shot the acog for the first time this week and it's was amazing, they are all good because in reality nobody is shooting back at me so my quest for the perfect all purpose optics isnt necessary. i have never put groups together like it did with the acog from a semi auto platform but that may be the scar 17.

I still don't get what you're trying to do with your ACOG.

The ACOG works perfectly fine for CQB. One must trust in the Bindon aiming concept - it works perfectly fine for most.
I have red dots and ACOGs, as well as magnified scopes, never have had any problem with two eyes open under about 3x or so - and have always used my ACOGs with two eyes open unless shooting longer distance shots when sometimes I will close my non-scope eye.

There's a reason I leave the acog off my duty rifle. It has 2 things on it... a buis (since I don't want to use a carry handle), and a vfg (because I can't use a hand stop). If they'd let me, I'd use a super compact rds like a rmr or aimpoint, and a hand stop. I'd also throw the stupid serpa holster in the garbage and get a kydex. But I digress...

I'm not trying to say that it doesn't work, because it does. It's not something I'd want to fight wit at my skill level, but for a single-way range, it's ok. I play around with it a bit, and find for MY eyes it doesn't work as well as it should. Maybe I need more live fire training. I think OP's problem may be more along the lines of him not controlling his focus point. It does take practice to make your eye focus on the main image (scope), and the off eye to just be peripheral until on target. I feel that the whole thing is really a work around, a compensation, for using the wrong tool for the job. Of course not all of us are (mall)operator enough to use a rds, thermal, acog, and nvg on the same rifle, which is why I question the intent of OP. It sounds like he wants to use the optic for closer ranges primarily. In lieu of using a close range sight. If his intent is to go for longer ranges, but wants to train for more necessity based close use, then it's a thing to worry about. Otherwise, just close your weak eye or learn to tune it out (which is basically the whole point of the BAC).

I should probably take an English class or two, so I can make a little more sense
