Both will work in a standard AR15/M16 lower. The HK416 version is equipped with a bit more metal at the top of the hammer to engage the HK416 "secondary safety". With that being said - the standard M16 version will also work in an HK416 but the "secondary safety" feature will not.

If you plan to ever own an HK416 upper it may be wise to purchase the HK version.
