I received and installed my brass sheridan RVA. These are top notch add-ons, the machining is extremely nice with nice angles and smooth curves. The parts match up perfectly. and the brass was polished as well.
He includes all stainless hardware so you will never have to worry about the part wearing out befor the gun does.
The RVA itself was lower profile than say the PPS RVA. And the spring guide is built in so no parts to lose.
