||I loved this gun as stock, but wanted a better headturner at the field...
Here was my setup for my M249:
SHS High Speed Motor
Matrix 8mm Bearing Bushings
Matrix Polycarb piston
CA Piston head
This thing was shooting 40-45 bb/s on a 11.1v 25c LiPo!
No need to waste money on the Echo1 Version of this gun! Buy this one, spend $120 in upgrades, and MAKE AN INSANE SUPPORT WEAPON
Only thing about this gun i didnt like was the box mag. It cant keep up with my ROF as well as i would like. So i use Flashmags. works great.
