HK416C 9.5`` Barrel MR556 Conversion

HK416A5 ( 416F ) 11.5`` Barrel MR556 Conversion
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 conversations 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.
Parts:
- Birdcage flash hider
- 416A5 quad rail foregrip w/ flip up front sight
