I got this Crosman 700 today I cleaned it up and took about 15 stuck pellets out of the barrel, it shoots great now!The board stock isn't my favorite but it's in pretty good shape they were made from 1967-1971 there is no serial number that I can find, so that's the best I can do on the age.
Interesting looking gun, what's its propulsion system ?
I have one of those I took in on a trade. It shoots well & is an interesting design. They won't load pointed pellets well due to the rotating loading chamber, but all others do well. Pretty quiet & powerful rifle.
