Things I liked: You get the special wrench you need to take the valve out of the gun. You get all of the seals you need.
Things I would have changed: A little more detailed set of instructions on handling procedures to reassemble it.
What others should know: The white Teflon check valve disk has a radius on one corner. No mention in the instructions as to which way the radius should go in. (facing front or back)
Things I liked: I like the idea that these parts are available.....
Things I would have changed: There are 3 parts that make up the sealing system in a 300 ( breech, bumper and piston ring...for $30 bucks and $8 bucks shipping ....wouldn't ya think they'd throw in a piston ring?....no-o-o-o...you gotta go hunt it down else where ....and pay through the nose for the part and the shipping bend over yet again....SELL ALL 3 PARTS TOGETHER...and ease up on the shipping for small parts.
What others should know: This is the Pyramid way...
Things I liked: I recently rebuilt three FWB 300's, one in pieces. The seals had deteriorated completely. These were easy to install, and I had them in in very short order. The quality of the seals was high and they functioned perfectly.
Things I would have changed: nothing
What others should know: If you don't feel very comfortable with a fairly complicated build, and don't have a spring compressor,don't attempt to install the piston seal yourself. Have a competent airgun gunsmith perform the service.
