ADJUSTABLE BLEED OFF GAS BLOCK

Superlative Arms Patented Bleed Off® Gas Block – .750 Set Screw

Upgrade your AR-15, AR-10, or LR-308 with the Superlative Arms Bleed Off® Gas Block, a high-performance component that improves cycling, reduces fouling, and enhances overall reliability. Unlike traditional adjustable gas blocks that restrict flow, the Bleed Off® system vents excess gas forward, keeping your rifle cooler, cleaner, and more efficient.

Whether you're tuning a suppressed SBR or refining a long-range precision build, this is one of our go-to gas blocks for serious setups.

Key Features

• Bleed Off® Gas Adjustment System
  Only the required amount of gas is used to cycle the bolt carrier; the rest is expelled forward, reducing blowback and heat.

• Reduced Wear & Recoil
  Lower pressure at the carrier helps extend BCG and upper receiver life while reducing recoil and improving control.

• External Adjustment Detent
  Carbon buildup won’t compromise the detent, giving you consistent tuning with no internal erosion or seizing.

• Suppressor-Friendly
  A must-have for suppressed and short-barreled rifles—Bleed Off® minimizes blowback while preserving reliability.

• Multiple Mounting Styles Available
  Choose from set screw or clamp-on configurations to suit your preference or barrel profile.

• Material & Color Options
  Available in both steel and lightweight titanium, and in black, silver, and FDE (Flat Dark Earth) finishes.

• Made in the USA

Why We Recommend It

After running this gas block on a wide variety of ARC and Grendel-based rifles, it’s clear this is a high-value upgrade. Especially on non-flow-through suppressed setups, the ability to adjust while bleeding off excess gas significantly improves the shooting experience.

We’re currently evaluating titanium versions for weight-conscious builds and comparing set screw vs. clamp-onconfigurations for accuracy and stability. Results so far have been great—and we’ll update with precision data soon.

Pro Build Tips

• Read the Instructions: Before installation, review the included Superlative Arms instructions thoroughly to avoid common setup issues.

• Inspect the Gas Block: Check the gas block and gas tube for burrs or debris that could impact alignment or sealing.

• Gas Tube Installation: If available, use a vice to hold the gas block (wrapped in a cloth to prevent scratches) when inserting the gas tube.

• Gas Block Alignment: Use a bore scope if you have one. Otherwise, a laser bore alignment tool works well for aligning the gas port.

• Torque Properly: Use a torque limiter when securing the set screws—do not exceed the recommended spec, as this could damage the barrel or affect performance.

• Match Parts: Whenever possible, match your gas tube brand to the BCG gas key brand to improve seal integrity and gas efficiency.

Tuning Tips

• Always Tune in Bleed Off Mode: Start your tuning with the Bleed Off system active. This helps reduce carbon fouling, lowers gas port turbulence, and ultimately extends barrel life.

• Suppressor Considerations: When running suppressed, you'll likely benefit most from this system. Use it to fine-tune for minimal recoil and gas blowback without compromising reliability.
