Seals sticking together was a common problem with the wide frame guns for some reason. Daisy stakes the barrel seal to hold it in place. Sometimes you can get away with installing a new seal using the original staking, but a used seal will likely never stay put by staking alone, even if you restake it. If you decide to restake it, be careful to not puncture the shroud. If you reuse the original barrel seal, thoroughly degrease everything first, including the seal and the face of the piston using alcohol. I wrote a little on this, you can see it here: http://forum.daisymuseum.com/model-96-repair_topic9935_post42734.html#42734




Wish I had seen this before I rebuilt my Model 99.  The original barrel seal had turned to mush and had the hole spring assembly stuck to the abutment washer.  When I got it out, the mushy barrel seal was stuck to the piston.  I didn't know the barrel seal needed to be staked with glue, so I just stuck the new one in and seated it with a wooden dowel.  The gun shoots great, so I figure the remaining mush from the old barrel seal is staking the new one.   But I probably need to disassemble the gun again and properly stake the seal with glue.   When I'm gone and my grandkids (if I ever have any) are given my BB guns, I want them to shoot and be reliable for years to come.

It'll probably be fine the way it is. The glue makes sure, but the original staking can hold the seal in place, too. So unless you have it come loose, I wouldn't worry about it.

Steve, your rubber piston and air tube is the first design Daisy used immediately after transitioning from leather seals to rubber. This design was short lived, so there are many who may have never seen such a setup. Note that the piston shown is a new part, not the original. The original style piston did not have a hole that went all the way through from front to back, nor was the air tube captured by the retainer pin. The second photo is the piston and air tube of a model 141 that used the same type of rubber piston with a blind air tube hole. The photo shows the lack of a hole through the back of the piston.
