Specifications for Superlative Arms Adjustable Bleed Off Gas Block: Manufacturer: Superlative Arms Fabric/Material: 416 Stainless Steel Gun Make: AR Platform Gun Model: AR-15 Condition: New Gas Block Journal Size-Length: 1 in Features of Superlative Arms Adjustable Bleed Off Gas Block The pressure used in the block is reduced only to the amount required to drive the bolt carrier. The remaining gas and pressure are bled out of the block allowing the system to run much cleaner and cooler. Reduction of wear on the bolt carrier group components and upper receiver. Reduction of felt recoil allowing for faster follow-up shots. Patented adjustment detent is located outside of the block and therefore no contamination. In Bleed Off Mode the gas adjustment screw does not restrict the gas flow; therefore there is no erosion or seizing of the screw and no loss of detent due to carbon build up. Although it is removable we have added a safety mechanism which stops you from unintentionally backing the screw all the way out. When using SBRs and/or suppressors the Bleed Off port allows the excessive pressure to be exhausted out of the block reducing blow back.
