Over the past decades, piston-driven AR systems have accumulated a great deal of attention because of their capacity to deliver running credibility comparable to the exceptionally reliable piston based AK platform. Among the numerous advantages of the AK, the system has been its own piston based operation that isolates performance gas pressures in the front to the rifle away from the shooter and bolt and trigger group. This piston-based system delivers a cooler and better running AK gun that produces reliability. Some bright people figured out ways to move that piston system within the AR-15 platform hence combining the truth of the AR-15 system with the credibility of the AK.

Some businesses were offering a short and long-stroke piston system. Long Stroke systems have the ops rod connected to the bolt carrier like Tavors and AKs. Op rods aren't connected to bolt support on short-stroke systems. The main compromise between the two is the designs of the long-stroke system are heavier but supply an integrated gas design that bleeds off-gases. The brand new Superlative Arms system extends this bleed off the ability to a minimal profile Brief Stroke system, all while nevertheless providing gas pressure adjustment. Let me point out that Superlative Arms is the co-patent holder of the design offered by Syrac Ordnance and was also its partner of the Syrac adjustable gas block and Piston system product line. Superlative Arms might have been supplying its range of plastic gas cubes and piston systems identical to Syrac's; nevertheless, they developed their very own unique gas bleed-off design. Superlative Arms bleed system is offered in a direct impingement adjustable gas block and in the co short-stroke low profile gas system. Though there are similarities, Superlative Arms is on the marketplace with their very own systems.

I have several of these Superlative Arms AR gas blocks and would buy again.

The Superlative Arms gas block Dose as advertised. Adjust gas tube flow from full to closed with the setscrew. Quality construction. Use this one to tune an AR10 - 6.5 Creedmoor for perfect cycling. I have no more bashed up cases, no more feed issues after installing and properly adjusting. Have one on AR15-6.5 Grendel, does the same.

I would buy Superlative Arms again

Works great. Have 2 Superlative Arms adjustable gas blocks now will be buying more. Put the last one on an over gassed pistol length 300 blk out. Just running supersonic ammo, and this gas block tuned it beautifully. Shoots like a dream and the recoil are practically nonexistent!

It makes my gas gun better than ever

The Superlative Arms adjustable gas block works as advertised. I now have the smoothest AR10 I could have imagined. No more needless BCG beatings, and cycling works like butter. The fit was perfect, and the bleed-off system works beautifully. When I installed a JP LMOS BCG and silent capture spring, I decided to install this gas block, and I now have my favorite gun.

Works very well

I purchased this AR Gas block to install on a 5.56 pencil barrel rifle build. Installation was easy, and adjustment went even easier. This is a great product, and when I build another rifle, this will be an included addition.
