Crosman .177 Steel Breech Kit
For Crosman 1377 P1377

  • The Crosman steel breech kits are a genuine Crosman upgrade part.

  • They replace your plastic breech on your 17xx line of pistols and rifles (1377 1740 1760 2300).

  • They are solid steel construction and infinitely more durable than the plastic breech that came on your gun.

  • They feature a 3/8" dovetail for mounting a scope.

  • The included Crosman instructions are notoriously inadequate, so I include my own 4-page printout.

  • You can convert to .177 with this breech kit plus applicable .177 barrel.
