I find that people who fuzz about the burst fire mode, SKS single-fire CQB or AK series (Included G3, in Sweden it's AK4) sucks in Long range (Ironsight) is awfully mistaken. Its more in how you learn to use your weapon or learn the spray / auto fire patterns and accuracy... I started playing PR in 0.91/95 versions and quickly adapted to every single weapon in the game by studying and testing the weapons.
Burst mode is very accurate and very ammo conservative, lets you fire 1 or 2 bursts with very accurate fire into the target and quickly maneuver, I agree on that 2 - 4 bullets out of those 2 bursts actually hits the target, but 2 bullets are lethal enough to put you out of the fight. AK series are one of the games most accurate single-fire weapons, the fact that they are made for superior fire overpower with auto fire their first 2 - 3 bullets in full auto fire has decreased accuracy, this gives in single fire significant accurate fire with first 2 or 3 bullets with 0.4 sec duration (fire 1 bullet, wait 0.4 sec (echo sound of the weapon) and fire again).
SKS in CQB works approximately as the 9mm does, the spray pattern and accuracy makes it one of the deadlies CQB weapons in the game due to accuracy and depending how trigger happy you are, best way is aim in the sight and walk back or forward, this is recommended for aggressive advance forward (pushing) or falling back (dunno how to explain it, in Swedish it's "V?xelvis bak?t/fram?t"). As I said SKS works like 9mm pistol, aim in, and walk forward firing - the single fire and the fact that SKS is a medium ranged Auto-sniper makes it's accuracy very deadly and powerful in CQB. (BUT SKS IN CQB DUEL IS LOST CAUSE).
This is how I learned and keep working on my accuracy and mastering the weapons in PR, been doing it since the beginning, even if this doesn't make sense for any of you, it works - and that's what counts
