The CMMG Low-Profile Gas Block (0.625") is a compact, rail-friendly gas block designed for AR-style builds where clearance under free-float handguards is important. Machined from durable 4140 chrome moly steel and supplied with installation screws, it’s an ideal replacement for an A2 front sight base when converting to a low-profile setup or upgrading to a free-float rail that covers the gas block.

Product Highlights

  • Low-profile design fits under many free-float handguards for clean, modern AR builds
  • 0.625" inside diameter (barrel journal) for compatibility with .625" barrels
  • 4140 chrome moly steel construction for strength and long service life
  • Includes installation screws for set-screw style mounting
  • Great for replacing an A2 front sight base when converting to a covered gas system
