The Malli 14 Antimateriaalitarkkuuskivääri (Model 14 Anti-Materiel Sniper Rifle) is a (fictional) production of Barrett Firearms Manufacturing for the Finnish Army. It is a straight derivative of the M14 EBR and Barrett M107 rifles, using a reinforced vintage-style polymer structure of the former, bolt-action (borrowed from the Barrett M98B) and the .50BMG caliber from the latter.
Its name, the Lahti-Barrett, comes from both the name of legendary Finnish firearms designer Aimo Lahti and the manufacturer's name.
M.14 is taken directly from the M14 EBR.
It features a unique "sleeve" for the M14 bolt carrier that directs ejected cases to the left.
