Some details of the new Proto Rail posted by Dave Youngblood on Matrix Owner:
The Proto Rail

Set operating pressure is 140 psi with no on board LPR. All standard tournament programming modes are featured. Hyper 2 regulator is standard as well as a 3D milled ASA which is direct mounted.

Sounds interesting! I guessed that there wouldn't be an LPR on there!
