Remington Express 11mm Dovetail Rail Rear Sight Replacement

thingiverse

11mm Dovetail rail replacement for the Remington Express air rifle's rear sight. Uses the existing holes in the receiver that the sight originally mounted with. The many holes in the mount are for scope stop pins, which are on a lot of scope mounts. Remix of my previous Picatinny design. I wanted to try a pistol scope with a one piece mount I had. As with the previous design, you should be able to reuse the original sight screws (though you'll still need one), and one more (M3x7 - M3x10). It's worth noting that the original M3 screwheads are a bit weak and might strip if you aren't careful. One problem with break barrel air rifles (and other break actions in general) is that the barrel will always lock in a slightly different position. As such, the point of impact may be different between each projectile fired when using a scope mounted on the receiver. This isn't a big problem on every break barrel airgun, but I found the variance shooting the Remington Express could be quite annoying. With something like a zero parallax reflex sight or airgun rated pistol scope, it could be useful. Overall this design isn't as functional as the picatinny design. It had to be longer to mount my pistol scope, and therefore is much more wobbly than the previous design. I wouldn't feel confident using it for much more than mounting something like a laser. That said, if I made it a bit beefier it might be ok. Even then, the original picatinny rail design is probably better for a laser.
