Superlative Arms Ar-15 Solid Adjustable Gas Block .936'' Stainless Steel
$101.24
The Superlative Arms AR-15 solid adjustable gas block in .936" stainless steel uses a patented bleed-off design that sets it apart from conventional adjustable blocks. Instead of restricting gas flow, this block meters pressure by venting excess gas away from the system, which means your rifle runs cooler, cleaner, and with noticeably less felt recoil. That's the kind of refinement that matters whether you're running a precision load at the range, tuning an SBR, or running a suppressor where backpressure can be a real headache.
The engineering here is thoughtful. The adjustment detent lives outside the gas block itself, so carbon buildup won't foul your adjustment or cause the screw to seize. Thirty locked positions give you fine control over the exact amount of gas your system needs, and a safety mechanism prevents accidentally backing the adjustment screw completely out. You get the gas block fully assembled, plus two 10-32 set screws, a gas tube roll pin, installation instructions, and a QR code for a video walkthrough—everything you need to get it installed.
Built from 416 stainless steel, this is a solid, no-frill part designed for shooters who want to dial in their AR-15's performance without fighting with a restrictive design. Solid attachment, proven design, straightforward setup.

Frequently Asked Questions
How does the Superlative Arms bleed-off design work differently from a standard adjustable gas block?
Instead of restricting gas flow through the block, the Superlative design bleeds excess pressure out of the block. This keeps only the gas needed to cycle the bolt carrier, while venting the rest. The result is lower operating pressure, less heat, reduced felt recoil, and a cleaner running gun.
Will this gas block work with my suppressor or short-barreled rifle?
Yes. The bleed-off port is specifically designed to handle the excessive backpressure generated by suppressors and SBRs, venting that pressure away from the system instead of allowing it to increase bolt carrier velocity.
What comes in the box?
You get the fully assembled gas block, two 10-32 x 3/16" set screws, one gas tube roll pin, one 3/32 x 6" L-shaped hex key, installation instructions, and a QR code linking to a video tutorial.
Is the adjustment screw prone to sticking or seizing?
No. The adjustment detent is located outside the gas block, which keeps it free from carbon contamination and prevents the screw from seizing. The bleed-off design also means the screw itself doesn't restrict gas flow, so there's no erosion to worry about.
