A 4-slot aluminium Picatinny rail made to fit the Crosman plastic breech, as
found on the 1322, 1377, 2240, 2250 and 2289 models.The rail can also be used
in combination with the Crosman steel breech.Metal parts should be used instead
of plastic/3D-printed parts when high accuracy is needed, due to the absolute
superiority of metals in stiffness.
The backside shape of the rail secures against horizontal rotation, while its
more centrally located screw point makes wiggling more unlikely. The
installation screw is included in the purchase.
