Superlative ARMS Adjustable Gas Block, .625" Bleed Off - Clamp On
The Superlative Arms patented “Bleed Off”, direct impingement, AR-15 gas block adjusts the gas flow by bleeding the gas out of the block instead of restricting the flow like conventional adjustable blocks. Results:
- 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.
- Patent pending adjustment detent is located outside of the block and therefore no contamination.
- The gas adjustment screw does not restrict the gas flow; therefore there is no erosion or seizing of the screw / 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 SBR’s and / or suppressors the bleed off port allows the excessive pressure to be exhausted out of the block reducing blow back.

Customer Ratings & Reviews
Works so far
I installed this Superlative ARMS Adjustable Gas Block on a 308 AR (M118) Criterion 22" barrel. It took me three shots to adjust it to a functional level. So far, so good.
Superlative ARMS .875
Bought it on sale. It was back ordered but Mounts Plus pulled thru. It's the best gas block ever. Easy to adjust and works flawlessly. I'm swapping all my other AR15s' & LR308s'.
