Product reviews for Trijicon Tenebraex killFLASH ARD for 3.5x35 ACOG

Not sure what more to write: 1) It fit well 2) It worked well I've put about 2000 rounds downrange since installing this, and haven't had a problem. It slightly reduces light, but at the ranges you'd be using this/ACOG at, it's a non-issue.

great for the acog for coyote hunting, its a no glare cover for the scope.. its not like super tight and it don't need to be for its purpose.

This really looks good on my Acog. Other reviews mentioned a slight loose fit and that is true. I don't think it is going to be an issue while shooting. For the money, I expected a better fit. I am not terribly disappointed in the purchase though.

This killFLAHS has a problem. It won't stay on the ACOG! The little "ears"/clips on the sides just isn't strong enough to keep it on. I'm shooting an H&K MR762A1 (in 7.62/308 cal) shooting Fed Gold Match 168 Gr, and after a couple shots, the right side keeps comes undone. The design depends on the ACOG front hood to have a lip. I wish there was an indent or better yet a hole on the ACOG.for it to properly hook onto. I also have another (older) ACOG on my H&K MR556A1 (in 5.62/223 cal) and the honeycomb has no problems. It uses a different mount to the ACOG. It has a large rubber band that holds it in place. It also has less recoil, but the design is much better suited for higher recoil. However, they don't seem to be selling this design anymore. So if you plan to get one, be warned it may not stay on. If I knew this earlier I may very well have skipped this product.

If you are going to mount this on a TA11 ACOG, THINK TWICE. This device fits loosely, rattles, and detaches with almost no effort...right out of the box. I do not believe this accessory, mounted to a TA11 ACOG, would stay attached to a service weapon under tactical/field conditions unless glued/taped/cemented in place.

Very little play, zero issues while firing, effectively reduces glare and eliminates reflective signature. The only thing I would change is adding an attachment point or band like the 4x32 kill flash

snug fit no sloppy fit. some reviews state loose fit not this one that I received you wont regret getting this

I think the tolerances of the retaining clips are a little off. This product rattles a slight bit on the ACOG. It does what it is supposed to do though.

Just put this on my TA11, and it works great. Clips on and holds through .308 recoil with no problem whatsoever.

This item worked perfect on my TA11. Good fit, snapped on and stayed in place after several range sessions. Used on my BCM 5.56.

Fit right no movement. Performed exactly as advertised. Would buy again.

Does as advertised.

way too much money for a cheesy plastic clip on kill flash. Only purchase if you really need it. I wouldn't buy it again. An appropriate price would be under 10 dollars, if that.

To start off with, mine has never come loose nor fallen off. It has the tiniest bit of shake but it's not noticeable. (You're not going to hear or feel it if you're moving around). I subtracted one star just because the honeycomb effect does very slightly impact the clarity of the glass. After a while you get used to it. I like it because it protects the glass from getting scratched. It's very obvious how to attach it. It's supposed to block your target from seeing your red dot. Well it does that but I also have the RMR on top and that thing puts out way more of a target than the main optic does from the receiving end.

Zeroed my ACOG the other day with this installed on my AR10, LOVE IT!

Although sold under the Trijicon label, I believe these are all made by Tenebraex. For their intended purpose, they do a good job, but they are not for everyone. The Anti-Reflection Device (ARD) or "Killflash" is really only for those people who want to avoid "glint" from the sun reflecting on their objective lens; otherwise it is a +$40 range toy. It will cut down on the light transmission through the scope, and can give a slightly foggy image, but it is better than the old taped over lens shades people once fabricated for the same purpose.

Does as intended and fit on ACOG well with no rattle or loose fit as some have claimed.

It's designed to reduce/eliminate reflections glinting off the objective lens that may alert live targets to your presence. In that respect, it works as designed. Some reviewers have mentioned that the fit is loose on the 3.5x35 Trijicon scopes. On mine, it doesn't really rattle, and isn't loose enough to pop off on it's own unless there's rough contact with it. I noticed that turning/twisting it after popping it on tends to friction fit the tabs more snugly to eliminate movement. If desired, it's also an option to put a small strip of black electrical tape on the lip of the scope that the tabs snap onto to ensure a snug fit. The killFLASH does dim the view through the scope slightly, but I haven't noticed a huge detrimental effect, even when looking through the scope at night. While a screw-on option as on the SDO/MGO would be best, and the elastic retained option for the 4x32 might possibly be better, this works just fine for me.

Cheap piece of garbage. Didn't get to use this once before the clip broke while transferring weapon in a padded case! Stay away from this. Way too expensive for the price they are charging. It's not worth $5.00 let alone $40.00.

Works like it suppose to and protects my lens. It just doesn't attach very securely. They need to make one like the ta31 kullflash where it attaches by a band and sits inside the housing. I tried to modify my old ta31 kf to fit but it just won't work. So this sadly is the only option for the ta11 . What would be really great is to make it a bit like the ta11mgo and have it thread in and have a flip cap built it. Cuz there is no way to get a flip cap on this at all.

No problems

Like everyone else that buys this, I am disappointed with the quality. This is just a piece of plastic and Ive almost broke it several times cleaning my scope. It is not a tight fit on my ACOG and Im sure on an AR-10 would not stay in place. It is just a matter of time before one of the lobes breaks off and I'm lowered to taping it in place or just throwing $50 in the trash. I would say buyer beware. Look for an alternative product.

The kill-flash snaps on to the ACOG and is designed to be "idiot-proof." It can only go on one way. The honeycomb mesh does not interfere with the use of the optic like any kill-flash. I would consider a kill-flash mandatory on any magnified optic or a dot sight that's mounted to a fighting rifle.

Pretty s***ty. Does not stay on and not convinced it won't damage my 1400 dollar ACOG. Not going to give it the chance.

These work great, but wish they had a more stable mounting system like ones for other scopes that actually screw in. Lost my first one in the woods somewhere so now I rigged up a way to lash it better to my ACOG. Not a big deal, but kind of a hassle.

made to fit and does not obstruct my view or darken the view that I can tell.

For all the people giving this a bad review. My suggestion is, then design your own you complainers.. this tennebraex device is excellent. Perfect fit, perfect design. If you don't like how it's a little loose.. your silly. A bit a electric tape and your good.. is rather use s little electric tape than not have this item..

well made, FIT GREAT, functions as advertised.
