1. This is super cool. Great job bringing some ingenuity and realism to airsoft, and at a great price.

B. Would it be possible to build one with a battery back-up for use on overcast nights and such?

and III. Any thoughts of selling completed sights? I don't currently have an ACOG replica so if I was to get one it would be easier for me to get one from you with this mod already done, rather then buying one, shipping it to you, then you modding it and shipping it back. Plus I would think you could work in a little more profit margin that way and it would be a model that you already know how to work on.

We thought of that but figured most people already have acogs or other scopes and they wouldn't be inclined to buy a new one. But if you don;t have one we could work something out.

Would you ever possibly consider doing a fiber optics setup to a G36 scoped rail that has the replica fiber optic red dot sight mounted above?

I'm kind of confused. Could you find a picture of it cause I don't really understand what time of scope you are talking about

I was intending to watch this thread until the question of selling complete units was answered. Like I said before, if the price is right, I'd pay for a completed unit.

I need to find acogs for cheap. I found some a while ago on ebay, but those have long since been sold. If you find them, I will buy them and modify them and sell them. Selling them new is based off the price.To sell it new I would say it would be another $25 for supplies, shipping it back, plus a little bit of profit.

Some of the older G36 models had a dual optic handle attached. Top being a red dot sight and beneath it would be a scope. The red dot also uses some sort of fiber optic sight on the real steal cause it adjusts its own brightness due to the lighting in the environment but is also powered by batteries to be used during the night. Just thought it would be a cool new project for you to try to attempt.

Chaos_1.0 · « **Reply #80 on:** February 26, 2011, 06:38:55 PM »

that looks easily doable. Do you have one that you want modified?

xdejablu3x · « **Reply #81 on:** February 26, 2011, 10:59:17 PM »

I may get one in the near future but it was just an idea to give you on other options you might want to try out. If I acquire one I'll definitely will let you know.

Yes, depending on the layout of the red dot and the space available inside, it's possible. I've thought about adding that to the one I made. I'm picturing a little LED hooked up to the original battery and switch and electrical taped to the fiber where it passes through the red dot body. You cover the LED and a section of fiber with electrical tape to make sure none of the LED's light gets out and gives you away. When the LED is on, the fiber can absorb plenty of light and project a nice dot for you.

Yeah, modding the system to have a backup LED for absolute dark nights is not a problem. All it takes is one small LED, an appropriate battery and a mini switch. Most mod's I've done so far have ample room to fit both the fiber optics a backup LED system to illuminate the fiber optics.

NightHawk871 · « **Reply #84 on:** May 22, 2011, 04:38:48 PM »

Or instead of worrying about batteries and all kinds of switches, you can always do like what we did in the Marines. Just go and buy those small (1") glowsticks, and tape it over the fiber optic cable. Instant illumination for night, and the glowsticks last hours. Plus the tape will cover the glowstick so no one else can see it.

Good idea though. I'm always worried about my red dot's batteries dying on me in the middle of a game.

Shabby · « **Reply #85 on:** June 20, 2011, 03:44:36 PM »

So I'm curious about doing this with an adjustable 3-9x40 scope. Aren't most scopes Nitrogen filled? How would this mod affect a scope? Has anyone tried this with a longer scope? Or just the ACOG Platform? I'd love to put a purple dot in my scope.

Chaos_1.0 · « **Reply #86 on:** June 26, 2011, 11:26:15 AM »

I wouldn't do this to a scope. Scopes are a little more complicated. Anything that has a led in it would be really easy though. I have put it on a normal red dot and an ACOG. I haven't really had time to try anything else.

dtab · « **Reply #87 on:** July 05, 2011, 06:30:41 PM »

I finally got the stomach to gut my 4x Illuminated ACOG with range finding crosshair and try this mod. It works fine just replace the LEDs with the fiber optic cable end and you're good to go. Windage and elevation still work fine.

Edit: The only diffenece I think there may be is that with a red dot the LED shines directly on the lens that reflects it back. With my cross hair scope the LED needed to illuminate a 2d object so the factory used a white piece of paper/plasic to diffuse the light to get it evenly on the reticle instead of a only a small dot of the reticle lighing up. I just left the paper in an let it do its job as before.

rankross1 · « **Reply #88 on:** July 05, 2011, 07:43:30 PM »

just got my ACOG sight back from chaos, works great and definitly worth the time i had to wait for him to perfect it, if your on the edge i would go for it.

Chaos_1.0 · « **Reply #89 on:** September 29, 2011, 10:38:50 PM »

So I've been really busy since I last posted here. Stupid college, tests and working over the summer. But I have free time now. So how many people are interested in a complete ACOG for $70 shipped and a red dot for $35 shipped?

dune titan · « **Reply #90 on:** September 29, 2011, 11:14:46 PM »

That price sounds right

vlade · « **Reply #91 on:** September 30, 2011, 08:32:03 PM »

How far can you bend these wires? Like could I weave with it?

Chaos_1.0 · « **Reply #92 on:** September 30, 2011, 08:59:07 PM »

You can bend it to about a 70 degree angle before it won't come back to straight. Why would you want to weave with it?

vlade · « **Reply #93 on:** October 01, 2011, 09:53:58 PM »

Becase I had the idea of doing a paracord style knife weave around a ACOG. Would it still work if bent that far?

Chaos_1.0 · « **Reply #94 on:** October 01, 2011, 09:58:39 PM »

Definitely not. It will break but that would be pretty epic if it did.

I registered here just to get involved in this discussion, which I find highly interesting.
First of all I have some questions. Do you, Chaos_1.0 or anybody else that has done something like this, think that the fiber
mod could be done to this scope:
http://www.ebay.com/itm/ACOG-TA31-RCO-Style-4x32-Illuminated-223-Remington-Reticle-Scope-w-killFLASH-/130582703828?pt=UK_SportingGoods_Hunting_ShootingSports_ET&hash=item1e6755eed4

with this reticle:

?

There is already a fake fiber so the outside shouldn't be a problem. also the reticle can be illuminated so I guess there must be a LED inside somewhere. Now do you think this could be done here? I read that earlier you stated it would be too weak for ill. a complete reticle, but here it's just the middle cross that is illuminated. I would also be happy with having just a illuminated dot at the reticle, or just parts of the cross illuminated.

Also as I am from Austria It's a pain in the a* to pay 30-40$ shipping for fiber optical cable from the US to Europe. Do you know any seller where shipping is cheaper?

Thanks in advance

Im pretty sure my buddy has that exact same scope and asked me to install fiber optic on it. However when I opened it the LED to illuminate the reticle was on the opposite (left) side of the fake fiper optic. To replace the fake with real the cable would need to go into the scope, wrap around the internal optics and then do a 180 to replace the LED, which was the only angle I could illuminate the reticle with out major cutting. Since it wasn't my scope I didnt proceed. I think it would be impossible to keep the LED function, but it could be possible to get the fiber optic to work. You would need very thin strands to allow flexibility and more of them to make up for the reduced transmission.

Illuminating the whole reticle is not too much of an issue in the scopes I have worked on. Stock they used a material (piece of clear plastic) to difuse the LED light so that the reticle does not have uneven brightness. The same principle can be applied to fiber optic cable you just might need a bit more light out of your cables.

.aZtec · « **Reply #97 on:** October 26, 2011, 02:46:44 PM »

In fact i like only the center being illuminated more anyway!
So what you are saying is that I need something like this:
http://www.fiberopticproducts.com/store/product_info.php?cPath=8_22&products_id=867

How much parallell strand do you think would be necessary for this to work?

Chaos_1.0 · « **Reply #98 on:** October 26, 2011, 02:58:22 PM »

If you get good fiber optic cable you can really bend it without breaking it. I would try to find someplace over in Europe that carries it and then buy a couple of sizes. I mean it doesn't cost that much so then you could see how much you can bend each one and see the biggest one you can use.

.aZtec · « **Reply #99 on:** October 26, 2011, 03:26:37 PM »

Problem is that I do not even know the correct term to search for these things.
Can't seem to find anything that goes by "fluorescent fiber"..
Btw.: How is the fiber normally "bent" to the forward direction?
Couldn't I just do it that way on the other half, so that the LED function is still persistent?
