You could be looking at up to $800 or more, all things dependent. The $400 - $600 range is a bit more likely, though.
No.
no, in fact there is no such scope where you can attach another on it, plus it would look stupid
Yes of course
A high end Sniper Scope can be picked up for 600$ however one could get a relatively good sniper scope for about 150 - 200 $. This price range would be ideal for hunting etc.
The sniper scope will attach to any level gun, but you have to be level 40 to actually gain the benefit of it.
Scope as in sniping? Well if its that yes.They have 4 sniper rifles.
No.
You can scope with the Dragon Sniper in Uncharted 2 by pressing and holding the L1 trigger on the PlayStation 3 controller.
The browning is typically your common sniper rifle with a scope added , but you could use a M240 , and put a scope on it , LIKE A BOSS
You already know this one! It's called a scope. There is thermal scope, ACOG scope. It is also called an optic.
Up to $700, depending on condition, rare/unique markings, etc.
price on such a weapon would depend on originality of parts to that era, and overall condition of rifle and scope. i would guess at $1500 +/-
