Repair kit fits these multi-pump guns made after 1995 & they have a compression tube that slides out of the assembly & does not need a special tool (has a cartridge valve & the valve is NOT soldered). It may be necessary to push out the assembly from the front of the tube: Benjamin 397 & 392 guns as well as Sheridan C9 (Silver Streak) & CB9 (Blue Streak). To determine if this kit is for you: Remove the screw in front of triggerguard to remove rear part of the stock Remove the pins or screws that hold the retention cap at the rear of the receiver Remove the guide pin, spring & hammer to reveal the compression tube If the brass compression tube comes out in one piece, then this is the kit you need If your gun has a rounded square hole with a valve stem sticking up through it, then you need the other repair kit (CR/Repairkit)
