Lazarabic's if I have Tenzin's Yak head (callout) or in FFA, Talbot's if I don't have Tenzin's Yak head, unless FFA.
So, I use the FAL a lot, it's my favorite gun, I also really love the AK as my other go to. I've never had the gun "jam" as people describe, but I can attest to the gun not firing immediately when I first scope in and start shooting, it'll every once in a long while start only on the third shot or so, but I have also experienced quite a bit of shooting into someone and no damage is taken. Yesterday I was head on and had bottle necked three enemies and they were in a line (Syria, where the first bridge and the broken wooden door is, I was entering the center from the other walkway across and they were coming through frwalkway token door), I shot TEN bullets into the first enemy and he didn't die.... So yeah I don't know what the heck that's about.
I love the FAL because it's just fun to use really, if I want an automatic I use and AK usually.
I just use a different gun against foreigners now unfortunately. Theres a fal guide here u might want to look at, some helpful stuff there. As for the delayed shots....
I've never really had that happen to me, it might be your controller, but I don't know lol
I use scope on the fal when sum1 gets the jump on me to sneak in a headshot(s) quicker. It saved me countless times in the past.
Its my fav gun because its so fun to use. The hit detection is so whack at times its annoying.
Its a challange to use, but real fun.
Make a habit at aiming at the head, that will definitly help u a lot, even against laggy players. But still expect to hand out many more shots than whats needed against laggers.
