My kit was missing the breach seal. Filed a claim for replacement kit. Description states the breach seal is included in kit despite not being pictures in a few of the photos. Seems like a good replacement. Looking forward to a speedy turnaround on the order.

Installation is a little difficult but the Utube video really helps.

My old b.b. gun wouldn't pump air anymore. This kit fixed all my problems. Back to shooting in the backyard. Thanks!

This fixed our issue and made the rifle good as new. I did watch a tear down video on YouTube for help as there are a ton of parts. You will need to buy a ball pin punch to get one of the pins out but that was super easy and the only special tool you'll need. I think it was a 7/32

Rifle lost power and could hardly push a pellet out of the barrel. Pulled valve and found crud built up inside. replaced with this one, along with the pump cup. This is the push-in style pump cup but my gun has a pin that holds it in place-- not a big deal at all, just drilled a small hole through the base and it fit perfectly. I also used a dowel and some 1000 grit sandpaper to polish up the inside of the piston tube and get a gentile crosshatch pattern (dowel was the same size as the tube, so I had to sand it down by hand, which allowed for a perfect and very snug fit). I applied a very small amount of silicone-based vacuum grease and then used a cloth to wipe it all away, with the aim of leaving a microscopic amount of the sealant embedded in the crosshatching. Reassembled (this is by far the hardest part), and it's like a new gun!

This repair kit brought my Crosman 2100 Classic back to life. The repair pieces looked identical to the original and fit well. The rebuild process took approximately an hour as there is a handful of parts to remove and replace when you split the case. No special tools were required.

Fit perfectly in the Crosman Classic 2100A. Like new now. It was a challenge to reassemble. It’s recommended to remove the body slowly and delicately; then take closeup pics from different angles. Take note of the tiny/small spring and BB detent at the top of the magazine. Insert the Sear with spring compression last for an easier reassemble.
