AERO .625 LOW PROFILE GAS BLOCK$35.99
Availability: In Stock
The BCM LGB625 gas block is a low-profile .625" gas block built for AR-15 and M16 platform rifles. If you're upgrading your upper receiver with a quality, no-nonsense gas block that won't interfere with your handguard or sight setup, this Bravo Company part delivers the durability and precision you expect from a Mil-Spec machined component. The phosphate finish stands up to the elements and daily use, and the design keeps your gas system clean and reliable without adding bulk.
This is machined steel built to Mil-Spec tolerances—the kind of part that works the first time and keeps working. The .625" bore accommodates standard rifle-length barrels and fits the tighter gas tube and block geometry of that configuration. Set screws provide secure mounting, and the low-profile footprint means you won't fight it for space or have to fiddle with sight height or handguard clearance.
Whether you're building a precision rifle, upgrading an existing AR, or putting together a lightweight patrol setup, the BCM LGB625 is the straightforward choice when you need a gas block that stays out of your way and handles its job. Black phosphate on high-grade steel means corrosion resistance without the fuss, so your rifle stays reliable in the field or at the range.

Yes, the LGB625 is designed for AR-15 and M16 barrels with .625" gas block diameter. Verify your barrel's gas block bore size before ordering—this model will not fit .750" gas tubes or blocks.
The LGB625 includes set screws for mounting to your barrel. Installation requires proper tools and alignment to ensure a secure, repeatable fit. If you're new to gas block installation, consider having a qualified gunsmith handle it to avoid timing issues.
Low-profile design maximizes clearance for your handguard and doesn't raise your sighting plane, so it works with both rail-mounted optics and traditional front sights without compatibility headaches. It's clean, purposeful engineering.
Black phosphate is a chemical conversion coating applied to the steel. It provides solid corrosion and wear resistance for field and range use, though it's not as thick as hard-anodize or nickel-boron. Routine maintenance and light oil keep it in service for years.
