This is apparently an ADF HK 416.
HK416C’s from England
Nice, recent submissions!!!
Can anyone ID this handguard used by the French during SOFINS 2019? Looks like a RAHG but keymod. I've only seen that used by airsofters.. PC: 1st pic @hillejames_combatphotographer 2nd pic @mrqs.photography
Also looks like some Troy carbon fiber handguards seen as well?
