Superlative Arms AR15 .750 Adjustable Piston System
*** Click on the link below for ordering info and pricing *** Description: Description •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. Spec: •Firearm Type: AR15 •Barrel Diameter: 0.750" •Piston Block Attachment Type: Solid, Set Screw •Piston Block Material and Finish: 416 SS, Melonite •Carrier: Ion Bonded, 1 pc.

| I just got a chance to take mine out to the range today to tune it in and I am very happy with the result and quality. It was easy to install, easy to adjust the gas system and functioned flawlessly. I highly recommend this kit if you are in the market for a piston conversion! |

Quoted:
Syrac Ordnance change names? Its not that Syrac changed names, the system is actually made by Superlative Arms with a few changes. The Superlative Arms block has a gas bleed off system that will allow the gas block to run cooler and with less erosion or carbon buildup on the adjustment screw. Also they offer both the clamp on version and a pinnable version. In addition they have great customer service. I can tell you as someone who has installed and shot the Superlative Arms system I am glad I bought it. If your looking for a piston conversion kit in my opinion this is the one to get. |
