A friend gave me a first gen C150 to reseal last year. The resealing was easy and the gun functions flawlessly shooting 310fps low power and 410fps on high power with cphp's. The only hard part was giving it back. I couldn't, so now I own it. Some minor "character" marks on mine but I decided to keep it in the condition that I bought it in. Super fun antique that can be enjoyed.
