Adjustable Gas Block

Our Rosco Adjustable Gas Block is purposely designed to be lined up perfectly with our barrels and gas ports to ensure reliable cycling every time. These Adjustable gas blocks pick up where our standard block leaves off and works perfectly for shooters that want to be able to control their gas flow for suppressed applications.

Rosco Manufacturing’s “Bloodline” series is our hardest working category. Whether you are an occasional builder, tactical shooter, or Law Enforcement Officer we have a product that will fit your needs. All our Bloodline accessories are designed to take the abuse from unconventional wear and tear that our customer may need to inflict on their platforms. This is the only way that we can make sure that we are producing a product that will perform time after time under the most austere of conditions. We are setting out to re-define the rules and we plan on letting our work do the talking…
