The Superlative Arms AR-15 .625in Clamp On Adjustable Piston System with Mid Length Op Rod and Left Hand configuration features Melonite and QPQ finish on the piston gas block, with a full auto Dark DLC carrier in black. This patented Bleed Off® mode gas piston system for the AR-15 platform adjusts gas flow by bleeding the gas out of the block instead of restricting the flow like conventional adjustable blocks.
The pressure used in the block is reduced only to the amount required to drive the bolt carrier, with the remaining gas and pressure bled out of the block, allowing the system to run much cleaner and cooler. This design provides reduction of wear on the bolt carrier group components and upper receiver, along with reduction of felt recoil allowing for faster follow-up shots. The 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, a safety mechanism stops you from unintentionally backing the screw all the way out. Note that the Superlative Arms Piston Kit does not come with a Bolt Assembly (bolt, cam pin, firing pin, or firing pin retainer), sold separately.
