I've ordered a complete Discovery air tube (stock internals) to install on my Crosman 2400 carbine in 22cal with 24" barrel. Is there anything special I need to do to the rifle or is it pretty much a bolt together project?? This may have been asked before but I am fairly new to airgunning and couldn't find any definate info on the search. Thanks for any help.

Disco valve, striker, striker spring, transfer port etc.? Then performance should be about the same as a Discovery, and the two should bolt together just fine.
(Am going to assume a steel breeched 2240 carbine).
If using some 2240 parts, be aware:
1. Some steel Crosman breeches use the old breech screw location, and those that do also use the old striker. New striker has a circular cut out to allow for the new breech screw's location.
2. There seems to be a difference in striker springs between the discovery and the 22XX guns.
