The Badger Ordnance Mk 12 SPR Gas Manifold is identical to Crane manufactured Gas Manifold for the NAVSPEC Mk 12 Mod 1 SPR, M4A1 Block 2, and Mk 18 RIS-II upper receivers. Machined from heat treated 416 Stainless and Black Oxide finished.
Note: Crane contracts have utilized Badger and Daniel Defense, as well as NAVSEA manufactured Mk12 gas blocks. These are the same fit and design. Different finishes.
Note: These are press fit with two set screws on the bottom. They are not drilled and pinned.
When installed with the RIS-II rail for the M4A1, there is a very nice even spacing on the underside for the bottom of the Mk12 gas block.
