Acog with buis

[windrider]

So i was browsing pictures the other day (cant find it now) and i noticed a picture of an ar15 with an Acog with a rear buis on it and it got me thinking. What the hell is the point of that? The thing requires no batteries and would survive the emp portion of a nuke and probably the blast too. A friend of mine said probably in case it gets shot, that made sense for a second then I though well what if the fixed front sight post gets shot should he/she have a front buis for the fixed front sight, what if you have fixed rear iron sights and your iron sight gets shot should you have a rear buis for your rear iron sight? The logic for it seemed extreme. So we all know a lot of zombie hunter guns have every accessory on them and will most likely just weigh down the rifle get in the way more than anything but all the lasers and flashlights on bolt actions do have some use, this seemed to me the first 100% useless feature but i remember the ar15 was very clean looking, it was very minimal and the only thing was that buis so im a little curious if there is something I am missing. Can anyone enlighten me?

What if you fell in a muddy puddle while you were sneaking around and the lens was coated in muck?

probably just wipe the mud off

if you think a BUIS on an Acog is pointless look up the Acog with Doc optic on top with a BUIS next to it. i think that one is overkill.

I am picturing an AR with full top rail, the rear half of the rail taken up by BUIS rear sights, and the front half taken up by front sights...


I'd photoshop it, but I'm tired.

The ACOG being a magnified optic can be hard to use to engage close targets. Because of this, you may find that you won't want to look through your optic to shoot (remove the optic through some quick release, mostly hold zero when reinstalled kind of way). Additionally, a lower 1/3 co-witness allows you to use your iron sights as if the optic weren't there if you rather not remove your ACOG.

Additionally, the ACOG does have glass, for whatever reason it gets damaged or loses zero, you have options.

In terms of how much backup anything you need... 1 is none, 2 is one. =)

You can't use cowitness with an ACOG as it's magnified.
OP, you probably haven't realized it yet but many shooters setup their rifles in the same way that they see on the news or through another visual medium. Functionality plays a back seat to aesthetics.

The ACOG being a magnified optic can be hard to use to engage close targets.

Although the b/u sights on the ACOG aren't that great either. They sit so high above the barrel that the CQB hold off coupled with the short sight radius makes them quite difficult to use effectively. I suppose with lots of practice one could get pretty good with it if they wanted to tho.

Both eyes open, and use like an Aimpoint.

Close targets are engaged by setting the chevron on the target and pulling the trigger. If it's too close to focus on, then the bullet strike will still be in the general area of the chevron.

Is OP talking about the RCO with BUIS built onto the top of it?

The ARMS ACOG mount and 40L BUS are manufactured to mount ajacent to each other on the M1913 rail. The only reason for this IMO is if the ACOG is damaged beyond use and unrepairable in the field, wherein you would remove the ACOG, pitch it, and deploy the 40L with your front sight. Obviously this would not happen while you are being engaged.

Can also practice the Bindon Aiming Concept with ACOG, both eyes open like mentioned above. No real need for a BUIS CQB with enough training.

no like a flip up buis, i think it was the magpul one on the picture I saw
