An Actual HK 416 Gas Block for Your Next Build
Whether you're looking to take your Heckler & Koch MR556 to the next level or you need that missing part for your HK 416 build, this is a genuine gas block pulled from an actual HK 416, so it's purpose-built for use on your gun, and it'll bring a host of reliability benefits, as well as a few other elements.
Unlike the gas block found on the H&K MR556, this genuine HK 416 gas block features the ambidextrous sling-point attachments found on the real deal, as well as the bayonet lug milled into the gas block on real HK 416 rifles. As an added safety and reliability bonus, these gas blocks also feature a correctly milled gas-relief hole.
This low-profile HK 416 gas block is designed for use with 10-inch barrels and will fit .750-inch gas-block journals.
