 Standard factory Crosman 1377 American Classic pump-tube, not modified, tuned or reworked in any way, straight from the Crosman factory.

 Many of these tubes have the pivot-pin holes slightly out of square, this is typical with most 13XX tubes right from the factory and that includes the 1300KT tubes from the Crosman Custom Shop. This causes the front barrel band to lean towards the left a little in most cases, rarely towards the right and occasionally one is centered pretty well. This isn't an issue when using barrel bands for longer barrels like the 1300KT and 2289G Backpacker versions, with the standard 1377/1322 version with a sight-blade the front sight will lean to one side a little.
