YHM-9383 Low Profile Gas Block .750″ Bore – Black Phosphate

Description

Made in the USA, the Yankee Hill Machine YHM-9383 is a low-profile gas block engineered for .750″ bore barrels. It replaces a standard front sight and provides a slim footprint for compatibility with longer forearms on shorter-barrel rifles. Manufactured from steel and finished in black phosphate, the block mounts using two set screws for a straightforward installation. The design supports common AR-style accessory configurations where a low-profile gas block is required.
