So I have an issue with rattling inside my Tasco 6-24X50 AOE..... Yes, I know Tasco isn't the most reliable brand to start off with and through some initial research I found that this problem is more common than not but, I really couldn't find a solution that I liked...

I bought this scope from a friend and at first had it mounted on a savage .17 hmr bolt action. I had no issues with the scope on that gun but then, decided to mount it on my Remington 783 which shoots .270 Winchester.... It shot alright at first with some inconsistency but, I could hit paper which, was all I was looking for.

After about 75 rounds or so this inconsistency got much worse to the point where I couldn't hit paper at all no matter what adjustments I made. I tried remounting and bore sighting it multiple times before finally realizing there was a rattling coming from the back end of the scope. 

Upon further inspection, I noticed the telescoping adjustment at the back of the scope is where the rattle comes from and the glass seems to have fallen out of the mold or whatever holds it in place. I'm young and don't have much experience with scopes but, I think anyone would know that's not right. 

My question is, was the switch to a gun with more recoil the cause of the problem and what are my options in repairing it? I'm fairly handy and have plenty of tools so if fixing it at home is an option I would love to take that route but, wanted to get as much info as I could before tearing it apart and completely ruining it. If that's not an option (which I expect it won't be) what is the next best move?

I have had this happen to 3 tasco world class scopes. They were all on ruger 10/22. It happened after many rounds and years of use though. I put one on a muzzle loader and it broke a lense loose in 1 shot.

I would bet the recoil of the rifle caliber was just to much for it. I think tascos are decent for lower priced .22 option but not a good choice for any centerfire rifle for long term reliability.

I'm not well versed on optics terms but, this scope has what I think is called a parallax adjustment on the front that ranges from 15 to 300 to ∞ (correct me if I'm wrong but from my understanding it's not a magnification adjustment and is used to focus correctly for the yardage you are shooting at). Taking this into consideration it doesn't make much sense for this scope to be mounted on a rimfire gun because I don't know many people who go out and shoot a .22 at anything over 100 yards.... 

I'm not saying you're wrong in any way it just doesn't make sense to me why a manufacturer would make a scope that can theoretically be used for long range shooting but not be able to withstand the recoil from a high power rifle..... It's a little frustrating to say the least!

If I do somehow manage to fix this thing your're saying I probably shouldn't put it back on anything more than a rimfire gun?

I really think you should put it in the trash and get another scope.  You've got your money's worth out of it.

Parallax.  http://opticstalk.com/what-exactly-is-parallax-anyway_topic5026.html

Parallax is used heavily for short range rimfire shooting, thus the reason it focus's down to 15 yards.  Rimfire target shooters require it. 

I am not saying it was designed to be a rimfire scope.  I am saying Tasco scopes in general are best used on rimfires as they are not capable of dealing with recoil long term as they are cheaply made scopes.  I have used a lot of tasco's over the years and all of them have failed.  Back before I understood the point of quality optics, I would just expect my Tasco's to at some point fail, then I would go buy another $30 Tasco and start over.

You can try to take it apart, but you will likely not be able to repair it.  But at this point you are broke down either way so go for it.

I would go buy another but, I'm in college and money is hard to come by and I don't want to have to keep buying, mounting, and sighting in scopes and I don't have enough to buy a better quality one....

I actually just got kind of frustrated with the scope over the course of this conversation and took it apart haha. There were two lenses in the rear portion where the rattle was coming from. It looked like both those lenses were mounted in the telescoping part that I described and they were held in by a spanner nut (which was not screwed in and fell right out when I got it apart). I put a tiny bit of loctite on that spanner nut and screwed everything back together....

After getting it back together the rattle is gone and the view through the scope looks good. Mounting it and going to the range tomorrow. Maybe it will hold if not I guess I'm going to have to start saving up for a nicer scope...

When considering the cost of scopes and mounts, it is important to consider the cost of ammo used when sighting in. It may be wise to spend money on a scope with good turrets instead of the extra ammo required to sight in a cheaper scope.
