@BicolorZulu It's not just the spread (I much prefer that term, call me a dinosaur if you must :D), but I do agree that everything about the gun coming together is what makes it broken:
Bugged damage drop off.
Innately large magazine.
Decent rate of fire.
Low recoil.
Low/non-existent spread.
Reasonable reload time.
All things combined, it hands-down wins as the best all-round gun.
I see other complain about the SVK 2-shot. I can maybe appreciate this being nerfed for long distance 2-shots but at least the SVK has draw-backs with it's 2 shot (very small magazine, slow rate of fire, longer reload time). SVK does well at its intended engagement range.
The PP-29 excels at all distances - even at longer ones it can outperform DMRs and even snipers, courtesy of its combination of features listed above.
