Don't get an echo 1 m14 because they are rebranded karts. For anyone who doesn't know, the kart m14 has horrible internals and shoddy externals. Be prepared to dump large sums of money to get acceptable performance. I've heard great things about the sr25 but if you're set on a m14 then I would suggest the cyma if you can find one in stock because I've heard very good things about them. Also with any m14 other than classic army and g&g the semi auto cutoff catch will eventually grind down and it will be full auto only. Hope this helps with your decision.
