I think this has only started being introduced in the last couple of years, before that it was the F1 Infanterie (the version with the rail retrofitted to the carry handle). Is this actually called the "FAMAS Surbaisse" though? This rifle has the FELIN integration so is a different rifle I think (possibly called "FAMAS FELIN" but don't know if this is a real name). This is a picture of troops training to deploy to Afghansitan in 2011 and the soldier shown has a Surbaisse which looks like this above variant but without the FELIN integrated forward grip:

On the topic of the FAMAS, anyone know why they stuck with the proprietary mag well on the FELIN variant rather than switching to a STANAG? The prototypes have switched back and forth between the two as it has evolved so they have obviously had trouble making their mind up. Are these newly built or retrofitted from old F1s (I hope not as the F1 has some pretty serious mechanical issues)? I also enjoy the fact with the FELIN variant that it has all the buttons and what not in the handle, which are currently totally useless as the most I have ever seen them deployed with at this point is an EOTech.
