Superlative Arms Bleed Off Adjustable Clamp - Gas Block - .625"

Unlike conventional adjustable gas blocks that restrict gas flow, the Superlative Arms Bleed Off Adjustable Gas Block redirects excess gas forward through a bleed-off port, delivering only the pressure needed to cycle the bolt. The result is a cleaner, cooler running action with significantly reduced gas blowback, especially beneficial for suppressed and SBR configurations.

The Superlative Arms Bleed Off Adjustable Gas Block is a bleed-off adjustable gas block designed for AR-15 and AR-10 platforms with .625" gas block journals.

Bleed-off design redirects excess gas forward instead of restricting flow, running cleaner and cooler. Adjustment detent located outside the block to prevent erosion and carbon seizing. Adjustment screw is removable with a built-in anti-loss mechanism.

Compatible with AR-15 and AR-10 barrels featuring a .625" gas block journal. Fits under most free-float handguards and works with standard gas tubes across pistol, carbine, mid-length, and rifle-length gas systems.

Machined from 416 Stainless Steel and finished with Matte Stainless Finish for reliable performance under the sustained heat and pressure of a gas system.

Ideal for suppressed rifles, SBR builds, and competition setups where reduced gas blowback, cleaner operation, and fine-tuned recoil control are priorities.

The Superlative Arms company has over thirty years of Aerospace Engineering and Manufacturing experience, leading to their fully tested, patent-pending bleed-off gas block designs and innovations.
