Product Info & Specs

Heckler & Koch HK416 Vented Gas Block – Factory New – For 10.4” Barrels

This is a factory original, genuine HK part manufactured in Germany.  Heckler and Koch is internationally recognized for their high quality products, commitment to excellence, and their unparalleled, innovation.  Made with HK’s “No Compromise” dedication to quality, be assured you are getting the highest quality materials machined to precise specifications, flawless and resilient expert finishing to yield an impeccable product with immaculate fit and stability.

This factory new, genuine OEM HK416 vented gas block is compatible with the 10.4-inch barreled HK416 & MR556 variants. Cast into the gas block are integral sling loops and bayonet lug. These gas blocks are the perfect backup or primary component to complete your HK416 build. Compatible with the MR556 and CR556 for those that want to swap the gas block for the HK416 version.  Many (but not all) are marked “10” on the side of the gas block.


These are factory vented gas blocks for 10.4-inch barrels.

These are the last of the last – we begged our European suppliers for more vented gas blocks, but they are completely sold out of vented and non-vented 10″ gas blocks.  Once these are gone, there are no more.
