Came across this gem at a gun show today. It was missing the bolt handle. Guy that had it for sale didn't know a thing about it. I showed him how it worked, as well as I could without the bolt handle. He wasn't even aware it was CO2 powered. Had it priced at $150, I walked out with it for $80. I figured, what the heck, probably needs seals but I can use another project and can make some kind of bolt handle. I put one empty and one new CO2 cartridge in it and much to my surprise, it holds gas and shoots strong. Used a brass machine screw for a handle till I can fashion something that looks better. This one has the single stage cocking, shoots about 600 fps. Seems accurate too. I may resell eventually but will keep it for a while.
I can only find a schematic of the second version. Does anyone know if this is the same handle??Terry, can you see if the bolt is the same as this version 2 schematic?
I'm quite sure bolt handles for all versions of the 400 are identical.Don R.
