Will
NOT fit the Crosman 160
Contains a new
factory .177 or .22 caliber barrel, together with 3 high quality
Parker Buna O rings and high quality set screw. This barrel is 14mm outside diameter. It is not a replacement for the QB78 Deluxe, which has a 15mm outside diameter barrel.
FOR SALE ONLY IN USA
Remove the existing
barrel by undoing the barrel set screw (Part Number 2800) and pulling
it straight out of the receiver. Insert the O rings in the guides
dry, then apply a little moly over the rings and that part of the
barrel which fits into the receiver before pushing them together.
It may be necessary to de-burr and/or slightly chamfer the front
of the receiver in order to accept the replacement barrel without
tearing the O rings as this WILL cause a loss of muzzle velocity.
You should use new O rings every time you re-install a barrel in
the receiver. Don't forget to use the high-quality replacement
set screw! The original set screw is removed using the metric Allen
wrench supplied with the gun, the replacement set screw is tightened
with a 3/32-inch wrench. Do not order unless you understand what
you are getting in to! Specially packaged by Archer Airguns. Contents:
