Aero Precision Low Profile Gas Block .936'' W/No Logo For Ar-15 Nitride

The Aero Precision Low Profile Gas Block in .936" diameter with nitride finish is a precision-engineered component designed for AR-15 builders and gunsmiths who demand reliable performance without aesthetic branding. This gas block fits barrels with .936" outside diameter and delivers the low-profile design that makes installation and integration with rail systems straightforward. Built from 4150 hardened steel with a nitride coating, it offers durability and corrosion resistance in a finish that's both functional and understated—ideal for those who prioritize substance over logos.

Whether you're assembling a hunting rifle, precision target gun, or duty-ready AR, a properly fitted gas block is fundamental to reliable cycling and consistent performance. The nitride finish provides excellent wear characteristics and requires minimal maintenance compared to phosphate alternatives. The low-profile geometry ensures it won't interfere with sight systems or rail-mounted accessories, giving you maximum flexibility in your build.

Installation uses steel set screws with knurled cup points (10-32 x 3/16") for secure, repeatable clamping without slippage. Aero Precision manufactures this component in the USA, reflecting the same attention to fit and finish you'll find throughout their product line. Note that a roll pin is not included, and we recommend avoiding red threadlocker on the set screws; if you use any threadlocker at all, the non-permanent variety is the safer choice to preserve the ability to service or adjust the block later.

Frequently Asked Questions

What barrel diameter does this gas block fit?

This Aero Precision gas block is designed for barrels with a .936" outside diameter. Confirm your barrel's OD before ordering, as gas blocks are diameter-specific and are not interchangeable across different sizes.

Can I use red threadlocker on the set screws?

Aero Precision does not recommend red (permanent) threadlocker on the set screw threads. If you choose to use threadlocker, use a non-permanent variety instead, which allows you to service or remove the block in the future without damage.

What's included in this package?

You receive the gas block and set screws. Note that a roll pin is not included; verify whether your build requires one based on your barrel configuration.

Is this gas block suitable for AR-15 builds?

Yes, this gas block is designed for AR-15 rifles with .936" diameter barrels and works equally well in hunting, target, or duty applications where a low-profile, logo-free component is preferred.
