I have two N80SB-1 framing nailers that were rebuilt with a full o-ring kit, gaskets (RBK8 kit), trigger valves and a piston bumper set in each gun. The piston drivers look very nice, no burrs, etc. The guns will fire, no problem, but they will NOT RETRACT! After all the parts that were changed, I'm concerned that something else is wrong......ANY ideas of what to do with these two things?

Check the exploded view on the web site or in the manual for improper sequence of reassembly.
If they worked prior to your "rebuild" then you did something wrong OR got the wrong parts.
Compare all your new parts to the old ones for dimensional differences.
Finally, call the Bostich help line OR send them in for the professionals to rebuild them.

I bought the guns in a mixed lot of tools, came with a couple hundred pounds of nails for the guns, I bought them untested. They DID NOT work when I tried them, both just blew air out of the triggers. I figured that I would just go through them top to bottom, tirggers, o-rings, etc, while I had them apart. I bought Bostitch brand parts, I am 99.9% sure that I have this together correctly. I will give Bostitch a call.
