Elcan Specter 1.5-6x 7.62 movement on base

[Hanse Davion]

I have recently noticed that my elcan as described in the title has some movement if pressure is applied on what appears to be the elevation setting. The base is secure to the rails and is not the source of the movement, that much I am sure. The movement comes at the connection of the optic to the ARMS mount itself.

I have looked online for others with this issue, and the only other relevant info I found was another person that seems to have the same issue over on AR15.com (Thread here- http://www.ar15.com/forums/t_3_18/587702_.html )

Can anyone confirm that this movement is normal as appears to be suggested on the AR15 thread? It does indeed appear that a spring is what holds the optic to the base on the elevation setting and this could be causing the movement. (The optic does not move down toward the rifle, only up when I apply pressure on the optic.)

Any help appreciated.

I don't have one and am not an expert on these, but I have read about them. As I remember, that is the way the elevation adjustment is designed. My recommendation would be to send an email to Raytheon/Elcan:

It seems according to Mr. Pettry that this movement is indeed normal, but I find it odd to say the least on a pricy optic such as the Elcan.

Admittedly, it's an unconventional design. That said, from what I've read the optic works quite well.

My understanding is the elevation adjustment has a dampening system on it.

If you don't touch it, it doesn't move POI (even under shock of fire in 223 or 308).

Also, there is that 'lock' tab that should be set once you're adjusted.

I have two of the nearly-same optic in the original SpectreDR 1X/4X form, as well as two other 'original' 3.4X Elcans from the late 90s and have zero issues.

The lock tab prevents the elevation adjustment knob from rotating, it doesn't prevent the optic moving in an upwards direction however. Granted, I do not seem to have issues holding zeros, however I hadn't noticed the movement in the past either, but I wasn't looking. Check your optics and see if you apply pressure in an upwards direction if it moves at all.

I have 12 of these sitting on the shelf in my armory because they will not hold zero very well on military weapons due to that movement you are talking about. The mounting system is not up to the task that the military demands of them. Im not saying they are junk but you wont find a whole lot of guys that have used them in combat that have much nice to say about them at least in stock configuration. The only reason they cost so much is they are manufactured by Raytheon.

I owned 2 specter dr. One was 1-4x 5.56 and one is 1.5-6x 7.62. I confirm that both of them have/had the movement as you describe and that is normal.
