I've actually found the 552SD to be very innacurate when you're sitting still - at least compared to it's M4 counterpart.
Anyway, I think the 552SD is best used in burst mode. If you're an M14 freak than by all means blow your lode like LuFeng and ToxicWarrior here into the walls, but if you aren't an M14 spammer like myself then I recommend burst mode (if not single shot). If you're sitting completely still your bullets won't be right on the dot, but compared to most other Terrorist-only weapons it's better because it's quieter.

Oh yeah and while I'm at it...
General rules of thumb:
- When fighting a Terrorist, keep your distance.
- When fighting a SEAL, get as close as possible.
Big long explanation that you only have to read if you don't believe me for whatever reason...
in other words LuFeng and/or AL GIORDINO:
- When fighting a Terrorist, keep your distance. All terrorist-only weapons are inaccurate at long range, and for the most part fire fast to compensate for that. The chances of you hitting someone after unloading 50 rounds in a certain direction are good anyway, but if you're at point blank - the chances of those 50 rounds going into you are a lot more... let's say prominent.
- When fighting a SEAL, get as close as possible. All SEAL-only weapons are very accurate weapons. In order to be good with a SEAL weapon, a player needs to aim and shoot - it's very reliable to have your crosshair on someone and then kill them. SEAL weapons also shoot slower than terrorist weapons (save for the 552[SD] and AK[47/74] that very few people actually use on any given SOCOM game anyway), so to make it harder for them to hit you - make them rely more on their point-blank shoot-on-a-dime accuracy at close range. Spray and pray for everyone!
Don't hate me cause im good and own seals with thier ***** SD's while they hide and cower from afar! Not my fault yall can't man up and fight toe to toe, just seems yall need more practice with aim while hiding or close combat skills, im sure me, al and tox can help ya out
Plus apparently you don't play with me much i rarely use the M14 now, i prefer my AK...this way its less whining while i whipe the floor with those ***** seals :D -Lu
