The Nexter still has got the capabilities to produce the FA MAS assault rifle. So, it can still do it.
to produce small arms must be competent people and a willingness to do what is not the case today.
nexter are working for most important military program as Caesar.
french army using foreign ammunition and the barrel of the Famas is italian (beretta)
RADON (MSBS) It almost certain winner for a new rifle for the army, as Iraq and Afghanistan finally opened eyes of brass that you cannot go any further with AK and it's clones. Yet SF still buy foreign weapons (mainly HK) and probably will buy it for next few years as RADON will mature. But for regular grunts RADON will be probably next weapon.
It took FNH about five years to take the SCAR from prototype to production. You don't want to rush these things or you end up with a mess like the Chinese QBZ 97 that the Chinese rushed into production so fast even the lead designer was unhappy with the production rifle.
I think it is just a proposal from the manufacurer side (the same situation with P99D called by Fabryka Broni unofficialy "Rad"), not an official name of the new assault rifle. We have the same situation with sniper rifle from OBRSM - the factory name was "Alex", but the military designate is "Bor", so... there is A CHANCE that a new weapon IF the MSBS-5,56 WILL be introduced to the Army WOULD got this name, but it is still not sealed yet.
