Available are the brass
one-piece bolts, which fit the plastic breech ONLY.
Also available are the two-piece
blued steel bolts, which fits all the typically available breeches.
These are the ones that ship with the Crosman Steel Breech and the Aluminum
Breech that I sell.
Also available are two-piece
stainless steel bolts, which feature a slightly elongated probe and a much
larger cocking handle. They fit all the typically available breeches.
All three varieties are
available in .177 and .22. They can all be polished and powder coated,
HOWEVER, the tolerances on the steel breeches is pretty night and since powder
is so thick, you run into problems.
The plastic breeches are much
looser and allow for custom colors on the bolts.
