Diabolus - Another Look!

Here's more of the Diabolus rifle including range time, high-speed video, and some looks inside. The Diabolus is sort of a hybrid between an Armalite AR-18 and an AR-15. It uses the bolt carrier riding on rods like the AR-18, but uses the cam pin in the vertical position like the AR-15. Uses standard AR-15 bolts, barrel extensions, firing pins and fire control parts. It has a unique gas system with a piston just forward of the trunnion, fed from a gas tube connected to a standard AR-15 gas block.
