Most conversions are done using a mixture of factory HK parts and high quality HK licensed parts. In many cases the factory parts are simply not available in the US. We are doing our best to bring you never before possible versions of the HK416 like the 416A5 and 416A7, with ambidextrous features. See below for details on each build. As always, contact us for custom builds and specific build options.

Although parts pricing and availability changes all the time, currently, the least expensive way to build an HK416A5 ( HK 416F ) semi automatic civilian rifle, SBR ( Short Barreled Rifle ) or pistol, is to start with the MR556. These conversions are as close as we can get, in the US, to the 416A5, especially at this price. We modify the MR barrel, machine the lower and fit the ambidextrous A5 controls, anodize, re-mark and replace all parts as necessary. The standard A5 conversion uses the factory MR upper and lower as well as a cosmetically modified MR gas block, to resemble the A5 adjustment knob. ( See below for “true A5” gas blocks and upper receivers ) Other build options are available using original 416 parts kits, aftermarket parts or any other combination. The A5 parts are extremely hard to get though, so we are doing our best and using a number of licensed parts to get these done. Just let us know what you need.

Although parts pricing and availability changes all the time, currently, the least expensive way to build an HK416C semi automatic civilian rifle, SBR ( Short Barreled Rifle ) or pistol, is to start with the MR556. Other build options are available using original 416C parts kits, aftermarket parts or any other combination. Just let us know what you need. The 416C conversion can be done a number of ways. We can modify the MR556 barrel or build with an aftermarket or factory barrel ( when available ). The modified MR556 barrel is converted to the 416C length ( 9.5″ ) and the flash hider will block/cover the original gas port hole. We can use various shortened buffer systems or pistol buffers. Also we re-mark/laser engrave the receiver and change out a few parts. See services and parts list below.
