The Industry Brand Field Rear Sight is a popular low cost, yet high quality upgrade for Crosman 1377 and 2240-type air pistols that are fitted with a steel breech.

This sight provides click adjustment for elevation and windage and is the correct height to match the front sight on these Crosman air pistols.

Archer Airguns is now supplying this sight with an additional sight leaf screw. This is because the factory screw is too long and can interfere with correct fitting onto scope rails. The replacement screw is the correct length and requires just a touch of black paint to blend in properly.

NOTE:
These sights will have some minor chips and cosmetic damage to the surface. This does not effect the functionality of the product and can often be rectified with a little black paint. Please do not order if you can not accept this situation.

Some customers have also found that this sight causes their 1377 or 2240 pistols to shoot high - particularly at short range - although most don't have this issue.

A couple of solutions to this are described in these blog posts:
