Pistons & Gas Blocks

The Superlative Arms patented "bleed off", 30 position, forward venting, adjustable gas blocks are utilized in both the direct impingement(DI) and the piston systems. Gas adjustments are made by bleeding the gas out of the block, forward away from the operator, instead of restricting the flow like conventional adjustable blocks.

This system is extremely effective in both systems resulting in the following:

  • The pressure used in the block is reduced only to the amount required to drive the bolt carrier. The remaining gas / pressure are bled out of the block allowing the system to run much cleaner and cooler.
  • Reduction of felt recoil.
  • Adjustment detent is located outside of the block avoiding contamination.
  • Gas adjustment screw does not restrict the gas flow; therefore, no erosion or seizing of the screw / no loss of detent due to carbon build up.  Although removable, a safety mechanism stops unintentional backing of the screw all the way out.
