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

Unlock the full potential of your AR-15 with the Superlative Arms .625" Adjustable Gas Block—an innovation that redefines how gas systems should work. Unlike traditional adjustable gas blocks that restrict flow, this patented “Bleed Off” design vents excess gas forward, away from the operator, resulting in a cleaner, cooler, and more efficient shooting experience.

Crafted from rugged 416 stainless steel and finished in corrosion-resistant Melonite QPQ, this clamp-on gas block is built for durability and precision. With 30 locked adjustment positions and a contamination-proof external detent, it offers unmatched control and reliability—even under the harshest conditions. Whether you're running a suppressed SBR or a precision rifle, this gas block minimizes blowback, reduces recoil, and extends the life of your bolt carrier group.

Patented Bleed-Off Design
Vents excess gas forward, reducing heat, carbon buildup, and blowback.

Cleaner & Cooler Operation
Only the necessary pressure drives the bolt carrier; the rest is safely expelled.

Reduced Recoil
Smoother cycling allows for faster, more accurate follow-up shots.

External Detent System
Adjustment detent is located outside the block to prevent contamination and carbon lock.

No Erosion or Seizing
Adjustment screw doesn’t restrict flow, eliminating wear and carbon buildup.

Clamp-On Attachment
Secure and easy installation without permanent barrel modifications.

Suppressor & SBR Friendly
Bleed-off port reduces excessive pressure and blowback in suppressed setups.
