Rosco V2 Non-Adjustable Gas Block Features The Rosco Manufacturing V2 Non-Adjustable Gas Block improves on the original Bloodline design with a knockout hole machined into the front of the block giving builders and armorers an easy way to drive the gas tube out during maintenance or barrel swaps. That small addition saves real time and frustration compared to gas blocks with no built in removal point. Refined tolerances on the V2 version help the block index and seat more precisely on the barrel reducing the chance of gas leakage or misalignment during assembly. These improvements build directly on the reliability Rosco s gas blocks are already known for among builders. Finished in black the gas block carries a clean functional look that matches most black rifle builds without drawing unnecessary attention. It ships complete with two set screws and two roll pins giving the builder everything needed to install the block without searching for additional hardware. At 4 by 1.5 by 1.5 inches and roughly 1 pound the block is compact and straightforward to work with during an upper build. This gas block gives AR platform builders a dependable easy to service option for managing gas system function.
