Thanks to the efforts of a number of customers, we've been able to confirm that the very popular Industry Brand Rear Field Sight fits perfectly onto a number of other airguns.
These include the Crosman 1322, 1377 and 2240 pistols fitted with steel Crosman factory breeches. You can see this sight on Archer Airguns Crosman 1377 parts page and also the Archer Airguns parts page for Crosman 2240 pistols.
Also the sight works with the Russian IZH-60 and IZH-61 air rifles.
And it fits the Industry Brand QB6 and various model B3 air rifles.
Here's a photograph of the Rear Field Sight fitted to Paul Manktelow's beautiful classic steel breech Crosman 1322 pistol:
The Industry Brand Rear Field Sight offers precise click-adjustable elevation and windage adjustments. It's a nice sight - especially at the attractive price.
As the sight leaf screw used by the factory is too long (!) and can hinder mounting on scope rails, Archer Airguns is now supplying an additional screw that is the correct length - it just needs a dab of black paint if required to blend in. You can file or grind the factory screw down to fit, or use the replacement screw as you choose!
