AeroPrecision
The Aero Precision Low Profile Gas Block in .936'' diameter with phosphate finish is a no-nonsense AR-15 component built for builders who want durability without the branding. Machined from 4150 hardened steel and coated in phosphate for corrosion resistance, this gas block keeps your barrel assembly slim and clean while handling the rigors of the range, hunting, or duty use. The low-profile design means it won't interfere with rail systems or optic mounting, making it a solid choice whether you're running a free-float setup or a standard handguard.
Gas block selection matters—it's the valve that meters energy from your barrel to cycle your bolt carrier group. Aero's reputation in the AR platform rests on no-frills engineering and tight tolerances, and this block reflects that. The phosphate finish is a time-tested military standard that stands up to hard use and doesn't demand babying. If you're assembling a rifle or swapping components on an existing build, this is the kind of part that disappears into your platform and just works.
Installation uses steel set screws (10-32 x 3/16, knurled cup point) for a secure fit on your barrel. One detail worth noting: Aero recommends avoiding red (permanent) thread locker on the set screw threads; if you choose to use thread locker at all, opt for the removable type. Made in the USA, this block comes without a roll pin—verify your barrel diameter before ordering to ensure fit.

This block is designed for barrels with a .936'' outside diameter. Verify your barrel's OD before purchasing—using the wrong size will result in a poor fit and reliability issues. Aero offers other sizes (.625'', .750'', .825'') for different barrel profiles.
A roll pin is not included with this block. You'll need to source one separately as part of your assembly process.
Aero specifically recommends against using red (permanent) thread locker on the set screw threads. If you choose to use thread locker, use only the removable variety to allow for future disassembly or adjustment.
Phosphate is a proven military-standard finish that's durable and corrosion-resistant. Aero offers both finishes depending on your preference and application—phosphate is a solid, cost-effective choice for most shooters and builders.
