Ammo Capacity

Honestly, does a sniper really need four magazines with 23 BBs?

I have two, is that good enough?

yeah its enough snipers don''t take that many shots most games but if your a DM just reload them

That should be fine. I only have one mag for my M24.

2 mags for a m324s(its nice and silent)\
I go through 1-1 1/2 per game

I go through at least two a game but usually no more than so you should be fine although my magazine claims to hold 23 if it gets past 20 the magazine kind of jams so I leave mine at about fifteen or twenty just to be safe because you don''t want a jam during an airsoft game . I almost never have to refill my magazines unless there is alot of action going on around me and even then I only have to refill two or three times . All in All two magazines on average and five with action is pretty good . So again you should be fine with just using your two magazines .
