This is one of my older projects. It is a 2" chamber and a 1/2" barrel which shoots nerf bullets or anything that fits in the barrel. It operates at around 80-85 psi and is pumped up with a bike pump that goes into a typical inner tube valve. Thoughts?

As was pointed out elsewhere, if that is ABS cellcore then 80-85 psi is definitely putting you at risk of converting your chamber into a pneumatic grenade.
