heh,
I'm slowly becomming a MP5 fan. Nothing wrong with an AR variant at all...
i kinda like the fact there aren't a ton of accessories for the MP5 series... it keeps it simple, and yet still a very effective weapon.
I love the slimmer and lighter mags. In my m4 full set up... I can carry 4 mags on my chest, 4 in my drop leg, and 6 on my belt pouches. Thats 14 AR mags.
Take the same set up...I can carry 6 mags on the chest, 6 in the drop leg, and 12 in my belt pouches for the MP5.
I primarily use Midcaps, so in AR situations... I can hold up to roughly 1400 ( 100 rnd mids ) rounds ready to go, on full load ( for field and OPs)
Most the time I only load up a few and carry less on me than I could carry.
or on the MP5 ( 190 round Mids) 4,560 rounds ( roughly) ready to go and loaded, using the SAME SPACE as the M4s take up.
The MP5 is lighter, the mags even loaded are lighter. Since it has limited rail space, it can't be "loaded down" with too much stuff to add to weight.
It has a generic higher ROF, making burst shots more accurate and consistent... still packs enough "punch" to be used as a primary ... but small enough to be maneuverable.
I didn't like the MP5 at first... it took me quite a while to grow into it's merits, and recently since I fixed and made mine perform much better ... I've become quite the fan of them now.
ARs are still , very common, and there are loads of aftermarket parts, and even options of models out there... which make them a highly desired AEG. I have em too... lol, nothing wrong with ARs.
