Original Winchester sight ramps in NRA very good to excellent condition.
Beginning in 1953, Winchester changed from a sight ramp which was integral to the barrel, to sight ramps which were silver soldered to the barrel. These are factory original sight ramps removed from the barrel and which require soldering or silver soldering to be installed onto a new barrel. They are ideal for restoring a barrel with a missing ramp.
The #5 ramp was used from 1953-1954 and is characterized by a stippled pattern on the sloped portion of the ramp, similar to barrels produced from 1936 thru 1952.
The #6 ramp was used from 1955-1957 and is characterized by 14 longitudinal striations on the sloped portion of the ramp.
The #7 ramp was used from 1958-1963 and is characterized by 18 longitudinal striations on the sloped portion of the ramp.
Standard rifle ramps are marked with a number 1 on the underside and are contoured to fit the Winchester #1 (standard) barrel contour for all calibers except .375 H&H and .458 Win Mag.
Featherweight rifle ramps are marked with a number 2 on the underside and are contoured to fit the Winchester Featherweight barrel contour for all calibers.
