Ar-15 Solid Titanium Adjustable Gas Block .875'' Black

The Superlative Arms AR-15 Solid Titanium Adjustable Gas Block in .875" diameter gives you direct control over your rifle's gas system, a crucial upgrade for shooters running suppressors, shooting subsonic ammunition, or fine-tuning reliability on a tight build. Unlike fixed gas blocks, an adjustable design lets you dial in the exact amount of gas cycling through your bolt carrier group—reducing felt recoil, lowering bolt carrier velocity, and extending component life without guesswork or multiple test sessions at the range.

Built from solid titanium, this gas block handles sustained fire and harsh conditions without the weight penalty of steel, and the black finish resists corrosion and blends with modern tactical setups. The .875" bore diameter fits standard AR-15 mid-length and carbine-length gas tubes, making it a drop-in solution for most modern piston-driven and direct-impingement builds. Installation requires removal of the barrel from the receiver and proper pinning or set-screw retention per manufacturer guidance.

Whether you're tuning a precision rifle, running a can, or building a reliable duty gun, an adjustable gas block transforms your AR-15 from a one-size-fits-all design into a rifle tailored to your ammunition, suppressor, and shot count. The Superlative Arms solid titanium construction ensures longevity and repeatability shot after shot.

Frequently Asked Questions

Will this gas block fit my AR-15 build?

The .875" bore diameter is the standard for AR-15 mid-length and carbine-length gas tubes. Verify your gas tube length (carbine, mid, or rifle) before ordering. This block requires barrel removal for installation.

Can I use an adjustable gas block with a suppressor?

Yes—adjustable gas blocks are commonly paired with suppressors to manage the increased backpressure and reduce excessive bolt velocity and wear.

What's the advantage of titanium over steel?

Solid titanium offers weight savings, superior corrosion resistance, and excellent durability under heat, making it ideal for demanding shooting conditions and extended firing sessions.
