Q: Where can I find a rear sight and elevation ramp for a Model 43 Winchester? Or will a buckhorn style for a Model 94 work?
A: The standard, barrel-mounted sight system for the Winchester M43 was Winchester’s No. 22K rear sight and 1B elevator, which was also the same rear sight applied to the Model 92 and 94 carbines in the post-World War II period. Finding an original might be difficult, but such items can and do turn up on popular Internet auction sites.
Aftermarket sights with a vintage appearance are produced by Marble’s. I believe the company’s No. 63 would be the correct replacement for the M43 if you prefer the flat-top style, meanwhile, the No. 64 (above) is a semi-buckhorn and the No. 65 is a full-buckhorn. These sights are available from any number of sources, including midwayusa.com.
