First off if you are not a big guy or just a beast, the m249 mk2 , from any brand, is not for you. I doubt tim could even hold it lol. (which might explain the lack of a review on a gun that deserves one)
I have had this gun for about a year now and this gun is a BEAST. Out of the box it performs about like most other m249's, but the actual internals completely outclass the others. Because of this i was able to put a m120 and a 9.6v 4200mah large type in this gun right after i got it, which gave me over 400 fps at 18rps. (Need i say more?) I have put 60,000 rounds through it with no problems at all. With this set up i outrange almost all other support gunners on my field, which normally has 100-200 people on it, and last n00b day had 700+ ,(bad karma in Tennessee. its a free field. if you want to check it out go to badkarmaairsoft.net) and i actually still have a better rof. IMHO it is more than worth the price tag.
The guns external build is completely solid. But it is classic army after all, so that is to be expected.
The box mag is mediocre at best, but really almost all m249 box mags have issues with jamming. The best one i have found is the MAG 2500rd.
easy to change spring
only saw that fits a large type
two parts and you get 400fps@18rps
metal flash hider with burnt orange paint
