Ar-15 Clamp On Titanium Adjustable Gas Block .936'' Black
$188.99
The Superlative Arms clamp-on adjustable gas block for AR-15 rifles with .936" barrel diameter offers a fundamentally different approach to tuning your direct impingement system. Instead of the conventional restriction method, this block uses a patented "bleed off" design that vents excess gas pressure outside the block itself. The result is a cleaner, cooler-running rifle with less felt recoil—especially noticeable when running suppressors or short-barreled uppers where excessive backpressure can be a real problem.
The design keeps your adjustment detent outside the gas block entirely, which means contamination from carbon buildup is essentially eliminated. Your adjustment screw won't seize, erode, or lose detent function over thousands of rounds—a genuine advantage over traditional adjustable blocks. A built-in safety mechanism prevents you from accidentally backing the screw completely out, so you get tuning control without the worry.
This clamp-on model installs easily without drilling or permanent modification to your barrel. The 416 stainless steel construction is durable and corrosion-resistant, and the unit weighs just 1.34 oz, so it won't burden your front end. Included are two socket head cap screws, a gas tube roll pin, and both an L-shaped hex key and QR code link to a video installation guide to get you set up right.

Frequently Asked Questions
Will this adjustable gas block work with my AR-15 SBR or suppressed upper?
Yes. The bleed-off design is particularly effective on short-barreled rifles and suppressed setups, where excess backpressure can be an issue. The block vents that pressure outside, helping your gun run cleaner and cooler even with higher-pressure configurations.
Does this gas block require barrel drilling or permanent installation?
No. This is a clamp-on model, so it secures to your barrel without drilling, tapping, or permanent modification. Installation is straightforward and reversible.
What comes in the box?
The assembled gas block, two 10-32 x 3/16" socket head cap screws, one gas tube roll pin, a 3/32 x 6" L-shaped hex key, and a QR code link to a video installation tutorial.
How does the bleed-off design differ from a traditional adjustable gas block?
Conventional adjustable blocks restrict gas flow through the screw. Superlative's design instead bleeds excess gas out of the block entirely. This reduces pressure wear on your adjustment mechanism, eliminates carbon buildup on the detent (which sits outside the block), and prevents seizing or loss of adjustment over time. You get a tunable, reliable gas block that stays clean and functions predictably.
