Luth-Ar
The Luth-AR AR-15 low profile gas block is a straightforward, Made in the USA component for builders and gunsmiths looking to run a slimmer profile on their rifle's handguard. If you're assembling an AR-15 with a low-profile rail system and need a gas block that won't interfere with your furniture or optic mounting, this .936" bore-size block keeps the gas tube tucked tight under slim handguards. The manganese phosphate finish provides corrosion resistance without the weight or bulk of a full-size block—a smart choice for anyone prioritizing a clean, compact build.
This gas block ships with two set screws and one roll pin, giving you the hardware needed to secure it to your barrel. The .936" inner diameter fits standard AR-15 barrel profiles; confirm your barrel's gas port size before ordering to ensure proper function. Assembly is straightforward: align the block over the gas port, use the set screws to hold it in place, and drive the roll pin through for a solid mechanical lock. It's a no-frills, no-nonsense part that does its job without theatrics.
Whether you're building a lightweight recce rifle, an MDR setup, or just want to clear up rail real estate, a low-profile gas block is a smart foundational choice. Luth-AR's reputation for domestic manufacturing and reliable AR-15 parts speaks for itself among serious builders.
