GB0299
The Senco Framing nailer SN325, SN325+ and the SNII+ all share most parts, LB3499 Washer Firing Valve seal, Bumper BB0151, All the O-rings. The bottom rail GB0299 is for the SN325+ only I think. Below is most of the kits and parts I have for the SN325 and SN325+ (PLUS). If you need a part and don’t see it, send me a text with the # on the right and I do what I can to help.
