I had though about removing the ACOG, installing the back up sight (sight that came with the rifle) and sighting it in, then removing it and reinstalling the ACOG. How repeatable is this? Hoping someone here can offer a better option.

You might look at something like this.....

Just do a search for "offset backup sights" on most search engines. There are a lot of different styles available.

Thank you for sharing this as a result of what I was looking for

My first thought was why would anyone need a "back up" for an ACOG. Then I remembered that some are battery powered. However, I opened and read and think that the term "back up" was not quite what the OP was thinking about. IMO, LTUME1978 was thinking about a 1x sight to switch to from the 4x ACOG for CQB.

I put a 4x ACOG on my M4 about a year or so ago and spent a little time getting used to and bonding with it. Getting it sighted in after installing it was frustrating, but once done, WOW!

Since putting it on I've also spent quite a bit of time practicing at multiple ranges from 3-200 yards. Mostly from 3-10 then some at 25, 50, 100, and a little at 200. Getting myself familiar with using the Bindon Aiming Concept ability to be able to use this sight at any range effectively and precisely if needed. Therefore, I don't have a need for a 1x CQB sight.

It was revived by a spammer.

Generally-speaking, nope. It's a simpler and stronger movement for the right wrist to twist inward towards the chest (while holding a rifle in the regular shooting position) than outward - which would put a right-side optic into view easily.

Which is why I haven't bought a of angled sights yet. I'm a lefty, and so far I haven't found a rear sight that is intended for a left-sided mount. So for that reason, I'll probably buy just the angled mount without a sight and then put my Fastfire II on it.

Differences or maybe similarities...?

Thanks

The Burris is the poor-man's ACOG. The Burris AR536 and AR332 are the same optic, but the former is a 5X36mm and the latter is a 3X32mm. All three have fairly short eye relief and, at least in my experience, work better with the rifle stock collapsed than with it extended.


The Burris optics have the same reticles and everything, and only vary by magnification power. They both have the same reticle, which is a fairly well thought out bullet drop compensating reticle which is regulated for 55 and 62 grain bullets out to 600 yards. The reticle is illuminated and can be set to red or green at 5 levels of brightness. When the illumination is off, you still have the black reticle with the same BDC regulation.

The Burris AR332 & AR536 reticle:



The ACOGs are all fixed power if I remember correctly, and the most popular magnification level seems to be 4X, although there are others. The better ones, have a fiberoptic doodad on the top which illuminates the reticle, and if I'm not mistaken, the higher end ones also have a tritium insert and/or batteries to power the reticle in lowlight/darkness. The reticles I have seen are fairly simple, but easy to use.


Sample ACOG reticles (not by any means the ONLY reticles):


The clarity of glass on the Burris is fairly decent, but on the ACOG it is superb. Trijicon scopes have REALLY good glass. I paid $399.00 for my AR536, and I think that AR332s are going for around $339.00. A decent ACOG will set you back around $1,000.00 on up, depending on model.

Hope this helps.

Which 45º mount did you use for the FastFire?

My AR has an "ACOG-like" optic—a Burris AR536. Like the ACOG, it does not have a long eye relief, and it is fixed power (5X). Consequently it hangs over the rear flip up sight, preventing it from being deployed unless the scope is removed. you can get a quick release mount for your ACOG that is guaranteed to return to within 1 MOA of zero after removing and then remounting the scope. That is close enough to zero to still be usable at any distance you're likely to use an AR. So if I pop off the optic, I can deploy the rear sight. BUT.....there's more! I have a Burris FastFire II reflex sight mounted on top of the AR536, and that is zeroed for 25 yards. So the BUIS are literally for a last resort.
