AAT-52 (AAT M.1952) / AA 7.62 NF-1 General Purpose Machine Gun (1950)
Not much-loved outside of France, the AAT52 was nevertheless the French standard general purpose machine gun since the early 1950s.
As a general purpose machine gun, the NF-1 can be fielded in a variety of forms. In the light machine gun role, it is fielded with a bipod (mounted under the barrel) and light barrel and can consequently be upgraded to a tripod with a heavy barrel. For vehicular forms, the NF-1 sees use in tanks (as coaxial mounts), vehicles, and fixed/rotary aircraft - the latter version fired either manually or electrically. A carrying handle is positioned at the rear of the barrel.
At its core, the new NF-1 can fire from a metal link 50-round belt feed from either a bipod or tripod mounting. The belt-feed mechanism is similar to that as found on the World War 2-era German MG42 series of general purpose machine guns. Operation is of delayed blowback via a two-piece bolt. The barrel measures in at 19.3 inches and is of 4-groove, right-hand twist. Cyclic rate-of-fire is roughly 700 rounds-per-minute.
By most accounts the AAT 52/FN-1 is a very average general purpose machine gun with little to recommend itself. Text ©2003-2013 www.MilitaryFactory.com • All Rights Reserved • No Reproduction Permitted
