It's not the best image, but I had to post a pic of my Uzi with an Eotech holographic site on it.

Just found these on Cabela's. Great price ($10.99) if you don't mind two-piece design. Also come in matte or gloss.

Re: Holographic Scopes have problems+2 good mounting ideas

Old Timer, any idea where to buy one of the ultra-lowprofile adapters? I've been searching and all I can find are the tri-rails which are higher than I'd like. Thanks.

Re: Optics! Holographic Inquiries.

When I bought my holographic sight I ordered the dovetail to weaver adapter mentioned in previous posts on this thread. It works fine, but I just realized something: the scope will mount perfectly on the top of the Drozd frame in front of the dovetail.



This part of the frame measures (roughly) 18 mm - just the right size for the Weaver mount to fit over! I'm guessing it'll also help with sighting in since the center of the reticle is closer to the center of the barrel. On the downside, I don't have the side rails anymore so I'll have to find somewhere else to mount the laser.

Re: Optics! Holographic Inquiries.

One thing I noticed about the seal in front of the mag (barrel nut seal) was that it is much thinner than a typical hardware store replacment ( at least mine was). With a thicker o-ring there was a noticably tighter fit against the mag.

Also, a worn out seal may allow the bb to knick the edge of the barrel as it leaves the mag.... I've noticed this mostly while modding airsoft guns, barrel extensions, and other projects and it wreaks havoc on accuracy.

Hope this helps:tongue:

Go here:

Then search the store for "holographic".

Hey jkdrozd,
I have seen on here somewhere a mod for ill fitting magazines. Radical chime in here please. If I remember right, he had a picture of the way he put in a metal shim to move the head of the magazine toward the barrel bushing. As far as the springer/Drozd comparrison, the two are worlds apart I agree. I don't think any of us bought the Drozd thinking it would be a tack driver. It is just a fun gun to tear things up with and put a smile on your face.

Re: Optics! Holographic Inquiries.

hey blurted,
i agree with your diagnosis there with my gun, messing with that adjustment does have a huge impact in a number of ways, including erratic firing, weak batteries will also show the same symptoms, but in my case it has plenty of power as each shot will tear thru both sides of a 1 gal paint can for the fullburst, my problem has to due partially to my magazine being worn and not fitting tight which allow the selonoid to not strike it equally each time and a crummy setup for the aiming, a weak laser & the original open sites so a big part is there
.... but in a nutshell the drozd doesn't fire consistantly like a springer, compared to my other rifle, it just doesn't have that hunter type of accuracy, but it'll shower whatever i want to hit & put a little kid grin on my face every time

Re: Optics! Holographic Inquiries.

jkdrozd,

Something is very wrong with your Drozd. If you messed with the trim pot, I would start there. Unless you have a leak somewhere. Even with C02, you should group tighter than you are. The only time I ever saw the bb's coming out of my Drozd was when I was using powerlets. After some rapid fire, the power drop would rear its ugly head and you could see them coming out. With that barrel you should be punching through sheet metal. Just my thoughts on your problem.

Thanks for the technical info. I figured the effect is normal but I just wanted to make sure.

Re: Optics! Holographic Inquiries.

interesting post & info you provided on the optics, amazing with how stuff works, plus like you said with the optics costing many times more, but still having the similiar issues , i want to get one for my drozd too, just haven't been able to as of yet, though when i shoot mine despite its 18 inch barrel it still throws the bb's like golf ball shots, i can't see these guns shooting tight groups from too far away, with mine and shooting quick single shots i would be doing good to keep them in a 3 inch grp @ 25 yards, i can see the bb's slicing & hooking like golf balls, a little bit of creative writing here though not up to my standards for serious hunting, a springer or high priced pcp is the trick for that, drozds for plinking

Re: Optics! Holographic Inquiries.


I noticed that a bit as well,and it even holds true with the Eotech and Bushnell series at 10 times the price.
Remember these sights have absolutely no optical correction or adjustment as do most typical scopes.You are required to use the other weaker eye to focus on the target image outside of the scope. Between the 2 images, both your eyes can have a little difficulty focusing on both something almost infinite and something bright within a few or more inches from your eye.
I don't think any of the more expensive reflex sights will allow the user to change the optical characteristics of the hologram projection lenses, and how they are focused on the viewing screen.

What I tend to do is just use either the small round dot or the central dot in the larger ring. The other reticles tend to more easily blur straight lines rather than they so round ones

NOW, if your eyes are almost perfect and you have no vision problems, what could be happening is a side effect of the technology and operation of the scope's optics.

The gold-like coating on the main acquisition screen is a dielectric(meaning "layered") mirror,much like the ones used in some lasers. It is not just one single totally reflective coating on the surface,or you wouldn't be able to see through it at all.
Instead,it is comprised of many multiple layers of semi-reflective coatings,each partially coated like a 2-way mirror, and good for 20 percent reflectance(the hologram to the eye)and 80 percent transmission( the target to the eye). This ratio varies with the number of total coatings and purpose,but there can be 50 or more micro-meter coatings like this on every mirror.

The spacing between each layer/coating is a critical distance; that spacing being a single wavelength in distance of the particular frequency that was used to created the holograms) This ensures that the Hologram(and its specific frequency) will be reflected from the screen and back to the shooter whi

Re: Optics! Holographic Inquiries.

I got one of the holographic sights you guys listed below on eBay. Having never used a red dot sight it takes some getting used to! One question: when I initially mounted it and turned it on, the reticle seemed out of focus. For example when I use the "cross" reticle I can see the cross and two ghost images of it. Is this normal? In full sunlight, and when I focus my eyes on a distant target, the effect isn't nearly as bad and it is shootable, but not as "crisp" as I'd like it to be.

It showed up today. Must have got caught up in customs because it took 30 days to get from Shanghai to here.

Maybe the dept of homeland security was doing a background check on you. You might be flagged as "possible terrorist" for "importing weapon components".

Yes they are. No problem seeing the reticles during daylight. Seven brightness settings help.

I ordered an adapted from sunclear trading on ebay. They appear to be the only seller that has dovetail to weaver adapters.

Has anyone else had problems with shipping?

I agree, they are made from top quality alloy - but the dodgy, ground in, UP and R arrow signs show it up a bit.

But who cares, it works excellently and looks the part.

Re: Optics! Holographic Inquiries.

I got my holo sight from e-bay after seeing this and for something so cheap, it really is the business!!!

I had to get the adaptor rail for it but that didn't cost much either (ebay again).

Took me all of 60 seconds to get it setup perfectly too!!

Thanks for the info about these holo sights, I was going to get a red dot or illuminted reticle sight but this is so much better and easier to use - not to mention the lot cost me less than £40 including shipping.
