Crosman Transfer Port Bushings
Restricted, Normal & Max Flow
For Crosman 2240 2250 2260 1322 1377 2289

I offer three types of Transfer Port Bushings.
  • Crosman used to (still does?) make a restricted transfer port bushing to artificially restrict velocity output. It features a reduced hole of about .08".
  • Next is the normal bushing found on all USA guns. This is a popular purchase for those needing a simple replacement part (PN 1322A026) or buyers from the UK, Canada or elsewhere that DO have the restricted bushing and want a larger opening.
  • Finally, another Alliance Hobby creation, is the Max Flow Bushing. This bushing has been properly reamed out to allow as much airflow as possible. It features a 13% diameter increase and a 24% area increase over the stock bushing. It's one of my most popular sellers and is an easy, cheap velocity upgrade.
  • The bushings are also available with the rubber bushing sleeve (130-036, the "square" o-ring that the bushing sits in). I call these TP Kits (transfer port kits).
