Bravo Company Manufacturing Low Profile AR-15 Gas Block – Set Screw – .750"

The Bravo Company Manufacturing Low Profile AR-15 Gas Block provides a dependable, precision-fit gas system component for rifles built around a .750" barrel gas journal. Machined to tight mil-spec tolerances, this non-adjustable steel gas block uses a compact two-set-screw design that fits beneath most free-float handguards while delivering secure, long-term performance.

Precision Fit for .750" Barrel Journals

BCM hones the internal diameter after machining and phosphate finishing to promote a snug, correct fit on compatible .750" gas block journals. This attention to fitment helps support consistent gas-system alignment during a proper installation.

Low-Profile Design for Free-Float Handguards

Its streamlined profile is designed to clear nearly any free-float AR handguard, making it a practical choice for modern AR-15 and compatible AR-308-pattern builds where space beneath the rail is limited.

Durable Steel Construction

Constructed from steel and finished in phosphate, this BCM gas block is built for the heat, pressure, and repeated use associated with rifle gas systems. It is a straightforward, non-adjustable option for shooters who want a durable fixed gas block without unnecessary complexity.

Frequently Asked Questions

Will this BCM gas block fit my AR-15 barrel?

It will fit barrels with a .750" diameter gas block journal. Measure or verify your barrel specifications before ordering.

Is this an adjustable gas block?

No. This is a fixed, non-adjustable gas block designed for a simple and durable gas-system setup.

Does this gas block fit under a free-float handguard?

Yes. Its low-profile design is intended to fit beneath nearly any free-float handguard, but clearance should always be confirmed with your specific rail.

Are the set screws included?

Yes. Two 10-32 x 3/16 knurled cup point set screws are included.

Does this gas block include a gas tube roll pin?

No. A gas tube roll pin is not included. You will need to reuse an existing roll pin or obtain one separately.

Can this be used on an AR-308 build?

Yes, provided the barrel uses a .750" gas block journal and the handguard has sufficient internal clearance.

What is the benefit of the phosphate finish?

The phosphate finish helps protect the steel gas block from wear and corrosion in demanding rifle-use conditions.

Why does gas block journal diameter matter?

The journal diameter determines fit. A .750" gas block must be paired with a .750" barrel gas journal for proper installation and alignment.
