Practical experience with ACOGs?

[Oleg Volk]

I have an EOTech red dot on one of my AR15s. I am thinking of putting a 3.5x full-size ACOG or a lower-magnification compact ACOG on the other (A2) AR rifle. However, I've had no personal experience with ACOGs and have yet to see one in person. At $600-900, I am not eager to buy one sight unseen. My shots would almost always be under 300m, using 55gr ball ammo from a 20" barrel.

Have questions:

1. Sully said a while ago that he wouldn't use optics for general issue in Minnesota due to frost, fogging and other practical problems connected to temperature extremes. Would that hold true for rain, exposure to direct sunlight, frost or not?

2. Does ACOG with illuminated reticle (tritium or tritium AND fiber optic) offer any advantages over EOTech 552
at 300m or closer?

3. Do ACOG scopes have any direct competition of similar ruggedness and clarity?

4. Has anyone used them for hunting or combat, and with what results?

 

[SodaPop]

The first time I looked threw one I was utterly unimpressed. The optics aren't much better than any 4x Leupold shotgun scope.

I've done a little research into ACOG's, and I've read mixed reviews on their reliabilty in the Armed Forces.

They use them in Afghanistan.

 

[rugerfreak]

Ditto on being unimpressed.

The one I looked through at the store was very fuzzy and blurry-------no way its worth the high price.

I have a carry handle 2x compact with red crosshair and fiber/tritium. Been with me for a long while now. I have nothing negative to say about it, the biggest user problem is learning a new cheekweld with the higher mount, not really a problem. Its height above bore axis will magnify your pain if you cannot get your head around line of sight vs. flight of bullet. Also will magnify canting errors, but those are both AR general scoping issues, not ACOG specific.

The scope is very rugged, optics still bright and unscratched, and I have gotten the gun(s) pretty dirty. I remove it when heavy cleaning to keep it away from solvents. What impresses me there is that it goes back on and maintains zero. I use the same tq and semi-perm(blue) loctite. I think the red crosshair is ideal for me, depending on light conditions and your eye the brightness varies in daylight, but you are always left with a fine crosshair that is easy to see. It does not wash out in sunlight like a dot sight is prone to do. I have gotten good hits shooting in half moon conditions where it was too dark to see the whole front sight tower. If you can see so much as a omving shadow it is toast. Quick aquisition.

I think over the dot you have the advantages are durability and no batteries. The aiming point is finer than many dots also. I want a Tri-power, but those are in short supply right now. Cool accessory is Tenebraex Killflash, but the bottom has to be cut away to allow iron sight usage. Or you can just quickly flip it off.

I've used mine in the rain, no problems, the thing is sealed up tight. Gasfilled, so snow and cold shouldn't be a problem either. I don't hunt with .223 and combat hasn't come to pass around here yet, so dunno. I use it in IPSC side matches to no detriment against all the Aimpoint Comp M2s, very fast handling even on my 20"(the way it should be) gun. My mark of usability is I've handed it to several novice shooters in the same match and had them all get good hits easily. For regular 3 gun I take it off so as to stay in Limited class.

If you ever put a bipod on with an ACOG, look out. With the iron sights you still lose track of the front sight on recoil and can only shoot so fast. On a bipod through the scope it's like a poor man's SAW, just pull trigger and observe hits. Gauranteed to get you tossed fromn a stodgy range, more fun than should be legal especially with tracers.

 

[Andrew Wyatt]

that's odd. my 4X32 ta01 is CLEAR. (it's on par with the schmidt and bender scopes mounted on AI rifles)


YMMV, but the 4X32 ACOG is probably the best all around .223 scope, because it's adequitely fast at close ranges and allows for at least a modecum of first shot hit ability at ranges out to 800 meters.


I detest the 3.5 power acogs (i hate the reticle and the donut of death thingy), but they do get used a lot at the SWAT match, along with the 4x32 TAO1 and TAO1NSN scopes.


I think this blurryness is because the scopes you looked at had gunk on the optics. an acog without grease or gunk on the lens is clear as the proverbial bell.

ACOGs are not only mil spec, but awesome scopes for cold weather hunting. I know many people who use them for wolf hunting in -40

Does ACOG with illuminated reticle (tritium or tritium AND fiber optic) offer any advantages over EOTech 552

Absolutely....far better optically, far sturdier...and if I recall the EOTECH use batteries...say no more....

3. Do ACOG scopes have any direct competition of similar ruggedness and clarity?

As rugged as anyhting out there....optically on the par with Leupold...they use Nikon glass that is coated by the same poeple who coat Leupold I beleive (will check on this)

You can go wrong with an ACOG...I use the TAO1NSN

 

[HK_UMP.45]

Oleg, if you don't need magnification, then you might want to look into Trijicon's Reflex II. FWIW I've found it durable and fast on target. The amber triangle reticle takes very little time to get comfortable with and there are no wash-out problems.

I have one mounted on a HK USC so I can't talk about accuracy past 100 yds but I've seen them mounted on ARs. The owners seemed happy with the optics

Some say that standing in a shadow and looking at a bright target area results in a dimmer reticle. This has not been my experience. The tritium illuminator compensates for the lack of light coming in through the fiber optics. YMMV.

Either way, Happy Shooting!

 

[Jeff White]

I have had a TAO-1 since 1988 or so. Very clear optics almost indestructable. The tritium is still bright after all this time.

It's currently mounted on a TA51 flattop adapter. Some don't like the short eye relief but I find it perfect for nose to charging handle cheekweld on an AR or M16.

I'll bring it with me next time I'm through Nashville.

I’ve had a couple of months to play with my new ACOG. It’s the 3.5X with red donut reticle. I like it.
The optics are crystal clear and the donut is extremely bright. Much brighter than any red dot sight I’ve used. It has so far been useful in all levels of light. The optics appear to be as good as any I’ve used including my Nikon and Zeiss scopes.
I wasn’t sure if I would like the 3.5X magnification, but I do like it. The magnification helps with target identification with no apparent loss of speed since you still use both eyes when aiming. It’s a very fast sighting system. Much faster than iron sights.
This past weekend I shot it side by side with an AR-15 which had some other manufacturer’s reflex type red dot on a forward mount and found this Trijicon to be quicker and a bit more precise.

I first mounted it on the carry handle of my A2 but did not care for the handle mount. I now have it mounted on my flat top. The flat top mount works better for me since I’m more comfortable with the cheek weld. Target acquisition seems a bit faster with the flat top mount.

I haven’t had this one in any serious weather yet but I expect it to perform well. It seems to be very well constructed.

I have only hunted coyotes with this one so far and it works very well on moving targets.
I’m considering buying another ACOG to mount on my AR-10 for big game hunting.

Pricey? Yes they are, but I guess you get what you pay for.

 

[BerettaNut92]

Oleg, Trijicon is in Michigan, I'm assuming the climate is similar?

How is our friend in Minnesota, have you heard from her?

 

[Bartholomew Roberts]

Oleg, I've got the full size 3.5x (TA11). If you are ever in the Dallas area, look me up and I'll be happy to let you give it a try.

1) Haven't had much opportunity to test for frost down here; but I've used it in light rain and definitely a lot of direct, bright sunlight with no issues. So far the temperature range I've used it in has been pretty mild - maybe 40-75F.

2. I compared the EOtech, Leupold CQT, TA01NSN, TA31 and TA11 head-to-head when I was shopping for sights. After brief comparison I dropped the CQT and TA01NSN from contention.
Out of the remainder, the TA11 and TA31 dominate the 150-300 range. From 50-150 there weren't any clear winners - speeds were similar with EOtech being the fastest but tighter hits from the ACOGs. Under 50, the EOtech regularly produced the best scores using IDPA targets and times; but I think part of that has to do with a slightly steeper learning curve for the ACOG as you get used to dot shift.

3. US Optics markets some scopes using the same concept as does a budget brand called Elite IR. I haven't used either so I can't comment to their ruggedness and clarity. Whatever the sight is, it will have to be pretty rugged to beat an ACOG.

4. I haven't. Someone at Tactical Forums had the TA31 (4x with fiber optic tube) in Afghanistan. The Marines purchased around 1000 TA31Fs and are using them in Iraq now. Have some friends deployed there with private purchase TA11s and am waiting to hear a full report from them.

Haven't ever seen any fuzzy or blurry ACOGs but they are designed to be used with both eyes open. You have to focus on the target and the reticle will appear very sharp and crisp in your field of vision. If you try to look through the scope at the reticle it will appear blurry. I can explain it with enough time; but it is a lot easier just to show someone.

 

[Oleg Volk]

How is our friend in Minnesota, have you heard from her?

Last I heard she was doing allright. Maybe Sully would know more?

Keeping both eyes open is easy with non-magnifying optic...but I had a hard time with 2x Aimpoint...eyes kept switching dominance. I better get my hands on an ACOG before buying...

 

[Correia]

Team Trijicon had a bunch of demo scopes at the WC3gun. I played around with a few of them and I was very impressed. I thought that they were clear, and had a good field of view.

My favorite was the 3.5x with the chevron style recticle and bullet drop compensator. It made hits on a 400 yard gong a piece of cake.

 

[Nero Steptoe]

I've been looking for ACOG's in the footage from Iraq; don't see too many, mostly "conventional" or red dot optics. I need more magnification than the ACOG offers. For what an ACOG costs, you can buy a real scope.

 

[El Rojo]

I have seen all sorts of ACOGs in Iraqi Freedom pictures. I think I have seen a fair number on the British Enfields too. The only experience I had with them was at the 2002 Shot Show. Oh I wanted one bad. Problem is I live in the PRK and can't get a AR-15 to go along with it, unless I want a FAB-10.

 

[FNFiveSeven]

Nero,

The ACOG *is* a "real" scope, actually, IMO it's better than most "real" scopes. Fantastic optics, excellent design (for a .223), super durable construction, tritium illumination (find that feature on another scope). I have a TA01 and love it, but I would like a TA11F better. BTW, trade, anyone...?

 

[sully]

The ACOG is a great optic. It works very well for most applications. My personal opinions on using optics on the AR15/M16 weapons system is that it depends what you are using the rifle for and in what type of enviroments. My personal application is for the Law Enforcement patrol car and tactical employment. My experiences with optics in this application here in Minnesota is that if you take the rifle from a warm patrol car out into the cold, the optics will fog temporarily. If the rifle is out in the cold for some time, and you go into a warm building then the optics will fog temporarily. This is why I am an iron site fan, no fogging. If you are in a consistent enviroment for tempature then fogging is usually not a concern. Also if you drop your rifle or bang your optic against something you might throw it out of zero. On my rifles I use the A1 upper receivers which can be dropped and banged without this concern. I also am able to consistently hit steel torso sized silhouette targets out to 700m with my iron sites, though I wish to try further sometime to see how far I can go. My being able to site in on long distance targets with iron sites I somewhat attribute to great vision, but a lot of people need the magnification to engage targets as well. I use Leupold Vari-X3's on my hunting rifles, and prarie dog rifles. Optics are a great choice for the right weapon system and the right application. The ACOG is a great optic. One just needs to consider their anticipated application, and what their preference is.

Oh yes, your friend is fine. I will tell her that she was inquired about.

Just my $.02

I find the mini-ACOGs to be more user friendly. They have much better eye relief and weigh next to nothing.

If you don't require magification, you mght consider the new Trijicon TriPower. I like it much better than the AimPoint.

Another option, though not "tactical looking" is either a low powered 2.5x fixed Leupold, or one of their 1.5x5 illuminated reticle scopes. Very handy. Works very well for CQB at the low setting and allows precision at your 300 yard envelope.

The biggest advantage I see for most defensive situations is that the scope provides a much, much faster hit than does iron sights, especially in low light.

 

[Navy joe]

I'm detecting a trend here. Everyone that has had them likes them a bunch. Many who have little to no experience with them find something wrong with them. Odd. Are there any "practical negative experiences" out there, or are some people just mad at what they can't buy?

Sully, on the fogging have you ever tried something like Fog-free or whatever anti-fogging stuff Rain-x makes? Just wondering, it never gets real cold down here, and the few times it has I've just left the gun in the truck overnight to stay acclimated.

 

[Oleg Volk]

All I want is a low-power (2x or so) scope with illuminated reticle. Other than East European scopes and Trijicon, who makes fixed power scopes with illumination?

 

[sully]

I've tried several anit-fog treatments and none seem to work. The fogging up you get is only temporary and goes away shortly, but it can be an issue in my applications. Our winters here get way below zero degrees, so we are dealing with extreme tempature changes. The other problem we have with that quick temporay fogging occurs with eye glasses and goggles as well. If you are stable tempature conditions then all is well, the temporary fogging issues occur when you have been in either the extreme cold outside for sometime that your optic is now very cold and then you have to rapidly deploy inside a warm building, or when your rifle is in your nicely heated squad car and you have to quickly deploy outside into the extreme cold as in felony car stops etc. On the ACOG itself I have nothing but good things to say, it is a great optic as well as others that are available.

[Oleg Volk]

If I get a scope, it would go onto a carry handle. I could still get a semblance of a sight picture under the mount, I suppose...wonder how badly that would interfere. I still can't point shoot AR15 well but will learn. Seems that pistol grips really get in the way of pointing a rifle.

 

[Jeff White]

Oleg,
You can use the iron sights with a TAO-1 mounted on the carry handle. The AR isn't hard to point shoot, but with the Trijicons you can access the irons anyway.

Jeff

 

[Badger Arms]

Oleg:

I'd do it the other way around. Instead of mounting your primary optic way above the sights and having an uncomfortable cheek weld, buy the ACOG with a backup iron sight like the Special Forces guns I've seen so often.

 

[Andrew Wyatt]

I mounted my ACOG tao1 in the carryhandle as well, and had narry a problem.
