How can you tell Mk.46 from M249 from Mk.48? The only visible difference I'm aware of is that Mk.46 lacks the mag feed option and Mk.48 would have larger rounds in the belt, but how can you tell otherwise?--Mandolin (talk) 19:58, 2 October 2017 (EDT)
417?
I looked at the stock photos and 417s have a forward assist. The rifle used doesn't have a forward assist Excalibur01 (talk) 16:54, 18 December 2017 (EST)
