2A ARMAMENT Builders Series Gas Block .750 Black

The Builder Series will provide a means for creating a multitude of 2A Armament components; receivers, gas blocks, bolt carriers, and gas tubes. The most notable feature with these items is each gas block is machined out of a single piece of steel. For added strength we have a black nitride finish. In many cases a small block machined out of steel can be hardened to improve its life and performance. We received many requests for steel gas block options and were happy to supply that option to our customers. You can be sure you will have a high quality, American made gas block as part of your 2A Armament build.
