Superlative Arms Ar-15 Clamp On Adjustable Gas Block .875'' Stainless$101.24
Availability: In Stock
The Superlative Arms AR-15 clamp-on adjustable gas block with .875" bore diameter takes a fundamentally different approach to tuning your direct impingement rifle. Instead of restricting gas flow like traditional adjustable blocks, this design uses a patented "bleed off" system that lets you dial in exactly the pressure needed to cycle the bolt carrier—then vents excess gas out of the block entirely. The result is a cleaner, cooler running system with less felt recoil and no carbon buildup on the adjustment mechanism.
If you're running an AR-15 with a suppressor or short-barreled upper, the bleed-off port is a genuine advantage. Suppressors drive backpressure up significantly; this block exhausts that excess pressure before it reaches your carrier group, reducing wear and improving reliability when you need it most. The adjustment detent lives outside the block—no contamination from carbon, no seized screws, no lost detent from fouling.
Installation is straightforward: clamp-on design, two 10-32 socket head cap screws, and a supplied gas tube roll pin. The block ships fully assembled, and Superlative includes 3/32" hex keys and a video tutorial QR code. A safety stop prevents you from accidentally backing the adjustment screw completely out. Built from 416 stainless steel and weighing just 1.34 oz, this is a refined piece of engineering for shooters serious about tuning their gas system.
| Bore Diameter | .875" |

| Length | 1.00" |
| Attachment Type | Clamp-on |
| Adjustment Location | Front of block |
| Finish | Black |
Yes. The bleed-off design is particularly effective with suppressors, which significantly increase backpressure. The block vents excess pressure out of the system instead of forcing it into your carrier group, improving reliability and reducing wear.
Traditional adjustable blocks restrict gas flow to tune pressure. This Superlative block instead vents excess gas—you dial in the minimum pressure needed to cycle the bolt, then the rest bleeds out. This keeps the system cleaner, cooler, and prevents carbon buildup on the adjustment screw.
No. It's a clamp-on design that requires no permanent modifications to your barrel. Installation uses the two included socket head cap screws and the gas tube roll pin. A video tutorial QR code and full instructions are included.
This model has a .875" bore diameter. Confirm your barrel diameter before ordering to ensure proper fit.
