The Fedorov Avtomat (also anglicized as Federov, Russian: Автомат Фёдорова) was an automatic rifle, designed by Vladimir Grigoryevich Fyodorov in 1915 and produced in the Russian Empire and later in the Russian Soviet Federative Socialist Republic.
Considered to be a "lighter than light machine gun" by Fedorov, it was designated as "Avtomat" (Russian for "automaton") by his superior, a term that in the modern day denotes an assault rifle. It originally fired a 6.5mm cartridge also designed by Fedorov. This was changed to the abundant 6.5×50mmSR Arisaka cartridge, purchased from Japan. The fixed magazine was replaced by a curved 25-round detachable box magazine, that was fed through the breech via 5-round stripper clips.
— In-game description
The Fedorov Avtomat is one of the three automatic rifles for the Medic kit. While doing the lowest max damage at close range, it features the highest rate of fire for the medic rifles to balance it out, making shot missing shots more forgiving. It has an average time to kill overall, but not as high compared to the other SLRs at longer ranges and won't beat most SMGs at close range, but respectable none the less.
The Fedorov is more for close range engagements. Namely any confrontation against an enemy player after 40 meters should be avoided and attempt to close the gap, its velocity is the lowest tied with the M1907 SL at 570 m/s with its minimum damage after 40 meters being up to six shots at a full health enemy combined with spread after such shots will result in rather poor accuracy. If shots at longer ranges are needed, it is recommended to use short controlled burst or slowly tap the trigger. Its recoil is relatively light compared to other rifles.
There are two variants of the Fedorov Avtomat: Trench and Optical. The differences between the variants is that the Trench offers better hipfire spread, which can be useful at close range making shots while hipfiring more accurate in the sense the cone of the spread is smaller, thus shots will hit more in that cone. The Optical variant offers better accuracy in the form of less ADS spread aiming down sights moving and not moving, less spread increase. Making shots at longer ranges more accurate. Whatever variant comes down to player preference.
