Reoccuring problem with a Vortex Scope

[.Scarecrow.]

I had purchased a Viper PST 1-4x24 and after shooting it was experiencing black specs in my field of view, presumably because of recoil from my AR-15. I had sent it back to Vortex to get it fixed and after I had done that it happened again. This time they recommended I have it replaced, so I did. I just got the new scope yesterday and shot it today. And guess what! Several black specs appeared after only 4 rounds. They are roughly half the size of a mil-dot or so. This is just bothering the crap out of me and I don't know if I should send this one back or what. Anyone have any suggestions?

On a side note, with this new scope I am also having some trouble when it is on 1x, immediately when I look through it I see a kind of double vision effect for a few seconds, this did not happen with my previous scope, same model of course.

Call them, and send it back.
After two defective scopes, I would be looking for something else to put on that rifle.

Did you adjust the eyepiece for your vision??

Pull up and look at the sky and see if the crosshairs are sharp.

If they are not, turn the ocular adjustment and pull up and look at the sky again.

Keep doing it until the crosshairs are clear & sharp.

Do Not just try to look through it and adjust it.

Your eye will try to compensate for the out of focus scope faster then you can screw the lends in & out.

As for black specs inside the scope?
The anti-reflective coating is chipping off the inside of the tube.
Send it back.

Just buy two more. That way you can one being repaired, one on its ways for repair, and one on your rifle.

About the focus with the optic. It is adjusted so the reticle is crisp. It's just that when I look through with both eyes open it creates a double image for a few seconds, then settles.

It's probably not at true 1x.

I would send it back. Are you dealing w/ Vortex or a dealer?

Just called Vortex, they are going to get some people together and find out what's going on. I told them they can put it on a rifle and fire it all they want to make sure it will hold up. I'm going to let them know I don't want the individual one I have right now, that I want a replacement that will for sure hold up.

When the interior coating flakes off like that it is generally an indication of improper mounting. I'd like to hear more about the mount you selected for your scope and your tightening procedure.

 

[taliv]

Weird. Never heard of that before but definitely contact them about it

 

[HKGuns]

Or, it could be a QC issue they've not encountered until you...Looking at the mount sounds like a good idea as well.

 

[Skylerbone]

Misalignment and/or crushed tube + recoil = flakes. I sincerely hope this doesn't turn out to be another 1" rings on a 30mm tube thread.

 

[.Scarecrow.]

Skylerbone, I have a Larue Tactical LT-104 with yes 30mm rings, for a 30mm tube. I put the rings on the rear of the scope so it would stay in place but still allow me to move it with ease. I then made sure the optic was level with the mount by taking a wrench and putting it level with the mount and making sure it was level with the flat portion of the scope, I put the bottom screws in first, then the top ones. I don't think I tightened them too hard. LaRue says to make sure they are snug, maybe my snug is different than their snug.

 

[Skylerbone]

Fair enough scarecrow, I ask because I do not know your equipment or methodology and I have read some real doozies. It would seem there is a problem with the riflescopes you received and I hope Vortex provides an adequate solution that is to your satisfaction.

 

[MountainBear]

You should get an inch/pound torque wrench. As you said, your idea of snug and theirs is probably different. If you want to mount your own scopes (power to you), have the proper equipment...

Buy whats called a "Level - Level - Level." A bubble setup for mounting scopes, can't go wrong then. Better than a wrench set up !

 

[madcratebuilder]

These specks inside the scope tube are often from over tightening the ring screws. Most screws are 15-20 inch pounds and LaRue is 20-25inlbs as I recall. This is very light, equivalent of two foot pounds.

Invest in a inch pound torque wrench for scopes, Brownells and Midway both sell them very reasonable.

The last time someone posted this problem it was a LaRue mount. If you don't follow the instructions they pinch the scope.

Looks like I have an order to place!

PS: You guys are great, thanks for the help.
