In the first couple years of the 700 a few guns came with slim 20" barrels. A letter I once received from Remington said that in the first 2 years of 700 production less than 5% in all available calibers were made with this barrel configuration. I have since lost the letter and wonder if anyone here has knowledge of this variant. I remember that these used to sell for double the price of the 22" barrel at gun shows the 80's.
