Some of the folks who got scopes on their rifles got some extra special deals, no?
The Colt pistol in 10 mm is a beauty!
Most scopes do not add much value to a deal, but some can. If it is a good quality scope, the value should be considered.
My policy is that the a scope should be of approximate equal value to the rifle it is on. I have had too many problems with inexpensive scopes. Mounting systems also create unneeded difficulties. A few rifles, such as the Ruger 77, have integral scope mounts that reduce the possiblity of error.
An exception is for .22 rifles. Just about any high power rifle scope, even if inexpensive, does very well on a .22.
