I installed a swiss arms cylinder, cylinder head and piston head and also an element piston. After about 1000-2000bbs the piston locked up to the back of the gearbox, and it ler me fire a few shots then locked up again over and over.

I opened the gearbox and found metaldust everywhere. The pistonhead had come lose and was barely attached to the piston and had scraped the inside of the cylinder. The Pistons teeths were also chewed up pretty bad, Worst at the piston tooth but also alot at the teeths closest to the piston head.

Im getting a new cylinder and piston but i really need help to figure what could have caused all this. Worth to note is that i completly forgot to fix aoe and loctiting the pistonhead screw, but could that have destroyed those piston teeths so bad?
Help plz!
Sorry for my half decent English and greetings from sweden 😊
