Superlative Arms Ar-15 Solid Ss Adjustable Gas Block .936'' Tan
The Superlative Arms AR-15 solid stainless steel adjustable gas block is engineered to give you cleaner, cooler, and more reliable operation on direct impingement rifles. Unlike conventional adjustable blocks that restrict gas flow, Superlative's patented "bleed off" design lets excess pressure escape through a port in the block itself—meaning you only use the gas needed to cycle the bolt, and the rest vents harmlessly away. The result is less fouling, lower temperatures, reduced felt recoil, and a gas adjustment system that won't seize or lose detent from carbon buildup. With 30 locked positions for fine-tuning, this .936" diameter block is a smart upgrade for shooters running suppressors, short-barreled rifles, or high-volume shooting where heat and reliability matter.
Built from 416 stainless steel, the block weighs just 1.37 ounces and measures 1.00" in length. The adjustment screw sits on the front of the block with an external detent—no internal contamination, no erosion risk, and a safety mechanism that prevents you from accidentally backing it out completely. Installation is straightforward: the block ships fully assembled with everything you need, including two 10-32 set screws, a gas tube roll pin, and a 3/32" hex key. Superlative even includes a QR-linked video tutorial to walk you through setup.
Whether you're tuning a precision rifle, suppressing recoil on a duty gun, or optimizing gas management on an SBR, this adjustable block gives you control without the headaches of conventional designs. If you run hard and want your AR to stay cleaner and cooler, this is a legitimate upgrade worth the investment.

Frequently Asked Questions
What barrel diameter does this gas block fit?
This block is designed for .936" diameter barrels, which is the standard size for most AR-15 rifles. Verify your barrel diameter before purchase to ensure proper fit.
Can I use this gas block with a suppressor?
Yes. The bleed-off port is specifically designed to handle the increased pressure from suppressors by venting excess gas out of the block. This reduces backpressure and helps keep your system running clean and cool.
What's included in the box?
The block ships fully assembled with two 10-32 x 3/16" set screws, one gas tube roll pin, a 3/32" L-shaped hex key for adjustments, and installation instructions with a QR code linking to a video tutorial.
How many gas positions does this block have?
The block offers 30 locked adjustment positions, allowing you to fine-tune gas flow for your specific setup. An external detent and safety mechanism prevent accidental movement or over-removal of the adjustment screw.
