Small guns - sneaker/critical build/sniper
If I had a chance to start completely over I would choose four eyes instead of small frame, so I suggest doing so. Than you can lower ag and add those point/s into PE, since you'll lose 1 point if using four eyes.
Adrenaline rush/quick recovery can be replaced with dodger, depending on your style of play or use BROF to gain more shots with handguns/less ap when using snipers.
If you're planing to do more sneaking than regular shooting - use bloodthirst perk, very useful when attacking 2+ players.
Guns good to use with this build :
DKS,M1C snipers best ones, but any sniper will do
Deagle,14mm,223 pistol - great low AP critical shooters, deagle best imo
Wazikashi blade,needler pistol - your sneaking arsenal
I buffed throwing coz grenades are awesome, if you can't get use to them, there is always good old milkor to solve problems.
If you're going to sneak - use leather jacket/combat/coat
Generally use any of the armors, but if you're going head on metal/combat armor can take a good beating, if shooting from more range, use leather family of armors for benefits or brof,recovery,healing.
Build treated me well, got over 300 kills with it ofc it took some skill and luck, but you can always disappear into thin air when things get tough.
Good luck wastelanders !
