Quite the opposite, in fact. While telescopic sights have improved in overall ruggedness in the past decades, there isn't one that is even slightly bulletproof.

Hardly. In fact that is a good way to not only see/loacte a sniper, but a good place if you are a good shot to aim if you are wanting to shoot him/her.

No why would they be , they are a tube with glass . I cannot see how they could ever be bulletproof

There are no telescopic sighting systems that are bulletproof. In fact, it would be a truism to say that a rifle scope is the most delicate assembly found on of any rifle, and is subject to misalignment if even moderately jarred.

Well, as I've said in a few comments, it is unlikely for it to be physically possible, given the way bullet proofing works: Bullet-proof glass, and bullet-proof vests both work because they spread the force of a bullet out across as much of its area as possible, a bullet hitting a normal scope would have only slightly more force than a bullet hitting a bullet-proof scope, the force of the bullet would be far too much for anything as small as a scope to handle, it would simply overpower it and blow it to pieces You would have to consider the size of the bullet being fired: It is probably possible for someone to bulletproof a scope against a .22 calibre bullet, but it would still damage the internal structure of the scope, making it very unlikely it will be of proper use to a sniper. Anything larger than a .22 (.303, .50, etc) simply have FAR too much force behind them for something as small and delicate as a scope to resist, it would tear through it, spraying shards of metal and glass, as well as the bullet itself straight into the face of the sniper using it (Forget it if a .50 is fired at you, they can kill you even if they miss, from the air pressure it creates going past you, *nasty* eh?) As Snooky said, the sights on a rifle are almost guaranteed to be the weakest point, serious sniper rifles are built to use as few working parts as possible, to create less possible interference with the bullet, and as such a more accurate shot, the only mechanism even possibly competing in complexity would be the loading system if it is a semi-automatic rifle, but true sniper rifles are bolt action (less moving parts = more accurate shots)

Yes and no. if you fire a high power rifle into the scope of a sniper rifle there ar so many lenses in the scope that the bullet would slow down and get deflected out the side of the scope, so while the sniper is still alive, he is now rendered harmless because his scope is torn open and most of the lenses broken. Update: after a mythbusters rvisit to this it was found that if the enemy sniper was using a scope from the '70s and the sniper shooting used an armor piercing bullet, you could shoot through the scope and embed a bullet in your enemy's brain.

no it can be shot out... look up storys from gunny hathcock usmc vietnam sniper....

The scope is not bulletproof, but it would probably stop a bullet considering the amount of glass in the scope. But bulletproof? NO WAY

Nothing is truly "bulletproof." Field optics are fairly rugged, but not bulletproof, at least none that I've used... :-)

Now the optics are not desiged a hit, even a less of a blow to the night vision optics

Only the ones that have a magnetic force field around them where all metal falls harmlessly to the wayside hence the naked eye of the scope remains unarmed. Yes this is future technology which has yet to be invented.

I did not know sniper optics to be bullit proof.

I guess it matters what bullet your shooting at it.

Hell no! I've had a round slap the scope clean off the top of my rifle while I was aiming through it!

During WW2 battle of Stalingrad in 1942 Soviet Army Sniper Vassili Zaitsev supposedly shot Major König of the Wehrmacht through his scope while the German was attempting to get the shot first. This account is legend in the Russian army, considering all the numerous deaths and the varied ways they took place, I see no reason to doubt it happened the way they said it did. I think I read an account of Carlos Hathcock repeating that feat against a VC or NVA sniper in Vietnam. I know of no scope designed to stop a bullet, and I would not buy one if it were sold for the simple reason that NOBODY would shoot through a scope if they had a more clear shot. Hitting anything glass or metal can deflect the shot and thereby miss the target while giving away your location.
