First time I’m seeing the 416A7 as selected by German SF, deets over at Soldier Systems Daily: http://soldiersystems.net/2017/10/13/spartanat-2/#comments
45 degree selectors and HKey in place of the quad pic. Not sure on other changes right now since the HK site still only displays the A5.
VERY similar rail to the one being proposed for the L85A3. I find it interesting the way some of these military arms are insisting on fitting parts that would be relevant on commercial ARs about 2-3 years ago. I had an original Fortis REV with the 12 and 6 o/clock pic rails and side KeyMod, was not a fan of the ergonomics, however I’ll take any weight saving over quad picatinny. That said of course, M-LOK all around is simply the way to go.
