i have tested all weapons in cs-go, and i will tell you the best accuracy weps, and how to use them
Pistols- fiveseven and p250(for terrorist)- with 5-7 you can spray and 15 out of 20 bullets will hit its target
AR-galil and famas, both weps, three round burst them and/or semi fire yourself
SMGs-ump is the best, another 3 round burst/spray wep, try to be close range and stay stationary mostly
Heavy-nova, stationary wep, aim for center mass or chest

This message is because i want yall to be great in survival and accuracy:)
