I'm working on a Longshot right now (AR removed; still need to plug the breech hole and add a new spring), and just for the fun of it, I wanted to wire in a laser-pointer as a quasi-sight.

I found a really cool tutorial to give an ordinary laser pointer an external power switch [here], so the electronics part is not what's holding me up. I just wanted to use the rail-clip attachment from the crosshair sight that came with the Longshot.

But I can't seem to get it open. I've removed all the screws, but the yellow caps at the end will NOT come free. I'd like to get them off without completely destroying the scope (I'm thinking of hiding the laser sight in there; not really sure, however). I just would prefer to do as little damage to it as possible.

I've searched around quite a bit, and I can't seem to find anyone who's really wanted to work on the scope and not bust it to pieces.

So my question is: Has anyone successfully gotten the scope open without too much damage? If so, how?!

Thanks so much.

I got mine apart fine. I just popped the caps off with a vice but make sure you put cloth between the vice and scope or it will scratch it to hell.

So you just clamped on to the yellow cap and... pulled?
(I ask to clarify, as that's been my approach to it this far, only just using my hands, and I've been unsuccessful)

I'll give it a shot though.
(Thanks!)

Yes that is what I did. Good luck.

I took all the screws out on mine, but instead of using the housing of the sight, I just took out the rail attachment and put a laser sight on that. I then promptly discarded that awful piece of crap scope.

Dremel slits along the part lines in the end rings, then the scope comes apart really easy.

I managed to wrestle off the top cap (the bigger of the two) after a lot of pushing, pulling, smashing with the screwdriver, etc. At one point I even threw it in the oven for a few minutes in an attempt to loosen the plastic...

But by looking at the now-removed top cap, I can only conclude that these things were glued on.
Which makes the outlook for getting the bottom cap off pretty grim... this stuff doesn't like to give.

I'll probably just try and beat/screw/smash the other end into submission... and when I get tired I'll probably end up dremeling along the two part lines, like telekinetic suggested.

I now know why I don't see the scope get modded that often:
It's a royal pain.

Thanks for the help, in any case.

I only opened mine to see if there was anything useful inside... Nope! I used my dremel to cut along the seam after taking the screws out. 'Twas a pain. I like taking things apart tho.

If it's anything like I think it is, get a industrial solvent. It'll destroy the glue. after working with the AT2K I wasted about 30 minutes wrestling the pump cap... also, I realized that the solvent is right behind me. I decided not to use it though...but, if you want to buy some industrial solvent and pop those sons o bitches right off! Make sure you clean it after words though.

WOnt most "industrial solvents" tend to melt the scope into goo, not to mention being very toxic?

Plastic isn't glue...

And any ways... Why can't you slice the rails off of the scope and throw the laser on to that?]

Prettiness is unnecessary unless you like to be purdy...he he....purdy

That's exactly it though.
The scope /looks/ awesome. Or at least I like it anyways. The only mitigating factor is that it's virtually useless. I wanted to give it some utility in safely housing a laser sight and its related electronics from getting shaken up or otherwise damaged in a hectic war-zone situation.

I finally figured out exactly how I /want/ to construct it, and purchased the parts. Now all that remains is the physical construction. I will try to post photographs or at the very least, schematics of the setup I hope to achieve.

Also: I had the same concerns as Galorn; not that it would melt the plastic, but perhaps destroy the stock finish on the scope, which is already looking pretty hacked up after the paces I've put it through.

More to follow.
