This listing will allow you to convert your 1377, 1322 pumper into a modded 2240.

The listing includes the main tube + internals, band kit and front sight. The sight has been slightly drilled out to accommodate the slightly different 13xx bbl's.

All parts are new, genuine Crosman.

The resulting gun will be a Crosman 2240 but with 10" barrel instead of the 2240's 7.5" barrel. It will look similar to the Crosman 2300T.

You have your choice of standard parts (factory valve and hammer spring) or, for $20 more, upgrade it with the Power Pack Plus, which is my Power valve, Power Spring and Max Flow Bushing.
