Griffin two position adjustable gas block

They just dropped this today. Pretty cool. Specifically the part where you can swap out manifolds and drill your own ports in the manifold plates. I've been drilling and tapping the gas ports in fixed gas blocks and using the grub screws as manifolds, by drilling them out with fine #48 or #52 bits. This allows for two settings and offers manifolds with pre-drilled 0.034" holes for you to open up. Complete customization for a dual rifle setting

Interesting concept, but I wonder how good of a seal you can get between the adjustment manifold and the body of the gas block. Someone used to make a similar design, but the manifold slid back and forth perpendicular to the bore axis. It was a leaker.

Agree. I'll find out. Ordered one to try out

It'll leak a tiny bit but probably less than the MicroMOA.
