After thinking hard about it(and still torn between this or some claymores), I starting to save up for an M249 SAW. My main decision here is which variant to get? Full stock, folding stock, or para? Please share your knowledge, opinions, and recommendations with me!
M249 MKII

Advantages: better "feel", since it's an LMG, and it's big like one should be; barrel length might help accuracy; easier to hip-fire; More balanced weight;
Disadvantages: Heavier than other models; large to maneuver in tighter places and transport.
M249 MKI

Advantages: Japanese-style stock in case I eventually get a JGSDF uniform; Stock is big enough to get an LMG "feel", but can be folded; Long barrel;
Disadvantages: Might be front-heavy due to skeletal stock;
M249 Para

Advantages: Compact for tighter places, or if I want to switch springs for CQB; Will transport much easier; might be lighter;
Disadvantages: Might not be as accurate: harder to transition from should to hip and vice-versa;
Please tell me what you think! Thanks!
