100, The - Season 1
The following weapons were used in Season 1 of the television series The 100:
Through most of Season 1, survivors of the original 100 used Colt M4A1 rifles that they salvage from an old weapons storage cache that was hidden over a century prior to their landing. Until the arrival of reinforcements, these are the only firearms used by the people from the space station (referred to by the natives as "the Sky People") while on the ground. Most notable users of the M4 Carbine during the first battles with the "Grounders" were Bellamy Blake (Bob Morley), Octavia Blake (Marie Avgeropoulos), Jasper Jordan (Devon Bostick), Monty Green (Christopher Larkin), Raven Reyes (Lindsey Morgan), Finn Collins (Thomas McDonell) and John Murphy (Richard Harmon), though many minor and single episode characters carried them during the first war with the Grounders in Season 1.
Mount Weather soldiers are seen armed with FN SCAR-Ls when they gas the remaining 100 members to sleep.
