Those interested in optimizing AR-15/M16 rifles for tactical duty will be interested to learn that Brownells® has introduced an easy-to-install modular gas block for the rifles. Designed to offer additional capacity and placement options for tactical rail-mounted accessories, the modular gas block a new addition in Brownells line of products.

The Brownells modular gas block features one integrated Picitinny (1913-style) rail, and allows the attachment of up to three additional Picitinny rails, which let you attach lights, back-up sights and a variety of other tactical rail-mounted accessories.
