As the cyber-soldiers leave their 'lair' while the group rests in the haven, their weapons can be identified by mid-90's Sci-Fi fans as 'Space: Above & Beyond' M-590 Marine rifles (note the scanners on the upper rail) and an 'Earth 2' MagPro rifle.
Quinn's rifle is based on the Calico M-100, which uses a round Helical fed magazine near the back of the rifle.
New season, new opening montage, new end credits music.
