Best gun for medic
Do you own the relevant DLC?
Miholaa, if you do have the DLC and still do not cannot select the special weapons try quitting Origin and re-start the Origin application.
Oh so I need to have DLC.
Autoloading extended is the king,
Fedorov Avtomat if you own the DLC, you can survive a shootout with automatico types out there and you can switch it to semi-auto for medium range engagements, when single bullet placement is critical
Depends on the range you want to play in:
Close-Quarters:
M1907 Trench
Autoloading 8 .25 Extended
Fedorov Avtomat Trench
Mid-Range:
Autoloading 8 .35 Marksman
Fedorov Avtomat Optical
Long-Range:
Autoloading 8 .35 Marksman
Mondragon Sniper
Selb 1906 sniper
Auto 8.35 marksman
Fedorov Avtomat
Pretty good list above
I would also include the RSC 1917 Factory and the RSC 1917 Optical at Mid - Range (DLC)
The Autoloading rifles are very underrated - I’ve been playing for a year and only recently discovered how awesome the Marksman variant is at almost any range. Want to “pick off” some snipers at their own game - Mondrogan Sniper 
The Selbstlader M1916 series of rifles are equally as impressive - Fast fire rates and big magazines.
Close range - AL 8.25 Extended - better start learning how to use this weapon, because when the new balance patch deploys, you won’t be able to win any close/medium fight with SMG/LMGs ever… Only AL will give you this chance.
Medium range - Probably still AL 8.25 Extended and also maybe Cei Rigotti (sic!) as with the new balance it will have it’s effective 3 shot kill increased to 70m and with it’s very good accuracy, rate of fire and low spread increase per shot - it should be a very good weapon for medium range engagement, same goes for AL though.
Long range - This patch - Selbstlader 1916 Marksman and new patch probably Mondragon Sniper. At the moment Mondragon is not very effective as extremely high spread increase per shot makes it effective rate of fire lower than Selbstlader’s and with only 10 bullets it’s a joke compared to it.
Next patch will make Avtomat even worse compared to any SMG/LMG and I don’t like 5/6 bullet weapons since those are simply not effective in use. Sure, if you camp in the corner and just pick one guy at a time - great, your k/d will go up, but in terms of PTFO they are way to slow in killing people, because lets be honest, how often do you get to engage 1 guy only and have time to reload and engage again, and reload… You see where I’m going with it? Camping - sure, PTFO - forget about them.
