They have marksman's rifles in 7.62×39mm, jobbed up to resemble AK-103s. These have all the usual improvements for such weapons: heavy match-grade barrel, custom-fitted stock and grip, and provisions for a bipod and a scope. With pod and optics removed, they can pass for AK-103s from afar . . . and while 7.62×39mm is crap for sniping, that choice maximizes ammo compatibility with the team's assault rifles and LMGs. More important, it means that all the group's weapons leave generic 7.62×39mm casings and holes, like all the AK-47s and AKMs kicking around the region. The snipers would've preferred a weapon in .300 Win Magnum, .338 Lapua Magnum, or at least 7.62×51mm, but the logistical and forensic risks weren't worth taking.
