CMMG 55DA3AC Low Profile Gas Block Chrome Moly Steel .750

The CMMG 55DA3AC Low Profile Gas Block delivers reliable gas system operation while maintaining a clean barrel profile for free-floating handguards. This precision-machined component ensures consistent cycling across various ammunition types and barrel lengths.

What Makes This Different

The low-profile design sits flush beneath most free-float handguards, eliminating the bulk of traditional front sight base gas blocks. Chrome moly steel construction provides superior corrosion resistance compared to standard carbon steel alternatives. The .750-inch diameter fits standard barrel journals, while the set screw and roll pin attachment system creates a secure, permanent installation that won't shift under rapid fire.

Key Features

• Low-profile design compatible with free-floating handguards
• Chrome moly steel construction for enhanced durability and corrosion resistance
• .750-inch inner diameter fits standard AR-15 barrel journals
• Set screw and roll pin attachment system ensures secure mounting
• Precision gas port alignment maintains consistent cycling
• Black oxide finish provides additional corrosion protection
• Made in USA with quality CMMG manufacturing standards

Field performance remains consistent across temperature extremes and extended firing sessions. The gas block maintains proper pressure regulation whether running suppressed or unsuppressed configurations. Competition shooters appreciate the clean barrel profile that doesn't interfere with lightweight handguard designs, while tactical users benefit from the reduced snag profile during dynamic movements.
