Superlative Arms Ar-15 Solid Adjustable Gas Block .875'' Black$103.49
Availability: In Stock
The Superlative Arms AR-15 solid adjustable gas block in stainless steel is a tuning workhorse for shooters running direct impingement rifle platforms. Unlike conventional gas blocks that throttle flow, this .875" block uses a patented bleed-off design to vent excess pressure out of the system while delivering only what you need to cycle the bolt carrier. The result: cooler, cleaner operation, less felt recoil, and reliable performance whether you're running a full-size rifle, an SBR, or a suppressed upper.
The design keeps adjustment simple and durable. The gas screw sits outside the block and doesn't restrict flow, so you won't deal with carbon seizing, erosion, or loss of detent from buildup. A safety stop prevents over-rotation, and the adjustment mechanism locks into 30 discrete positions so you can dial in exactly the gas volume your gun needs without guessing. A QR code and installation guide walk you through setup, and the package includes everything: two set screws, a roll pin, and an L-shaped hex key.
Stainless construction stands up to long shooting sessions and variable conditions. Whether you're tuning a hunting rifle for flat shooting and reliability, dialing in a competition platform, or optimizing a short-barrel or suppressed build, the bleed-off principle handles excess pressure that would otherwise beat your components and slow your transitions.

The Superlative Arms solid adjustable gas block fits AR-15 barrels with a .875" journal diameter. Confirm your barrel diameter before purchasing to ensure compatibility.
Conventional blocks restrict gas flow, which can cause erosion and carbon buildup on the adjustment screw. This Superlative Arms block vents excess pressure out of the system instead, reducing fouling, preventing screw seizing, and keeping your rifle running cooler and cleaner.
Yes. The bleed-off port on the front of the block exhausts excessive pressure that suppressors and SBRs generate, helping reduce backpressure and improving reliability on those platforms.
The block arrives fully assembled with two 10-32 x 3/16" set screws, one gas tube roll pin, one 3/32 x 6" L-shaped hex key, installation instructions, and a QR code linking to a video tutorial.
