That is an amzing build you have accompished!!, I am curious about those regulators, they look like on/off ASA but in regulator form could you enlighten me about those?

It's got some port work done throughout. Dual seal mountain air custom flat top piston. DIY flat top valve. The mod that sends it over the top is a mod where a steel pin is fit into the inlet valve face that almost entirely fills the inlet port for the valve body. This raises compression drastically.585fps on 10 pumps is impressive, what mods do you have in it? I've looked at those PCP conversions and they sound tempting.
