||Picked up this gun 3 weeks ago, got it all broken in, and I am in love.
Shoots very well (as it should) accurate to 150ft (all I have tested)
With regards to battery questions -
Mine and my gf's are wired rear, (they are both black)
My friend got dark earth and it is front wired (I hear all DE are front wired)
battery fitment: the G&P 7.4 1200mah 20C lipo fits perfectly in the buffer tube on this gun - please go in asking for the right battery because I was sold a wrong battery the first time (I now know better) aslo, it comes with mini deans style connector, and the G&P batt COME WITH THEM (be sure to get the one with mini, not full size connector)
Gun details: The "bolt cover" was VERY tight on all three of out guns @ first, they simply need breaking in + a touch of oil.
The selector switch can be finicky at first fresh out of the box because G&P makes the tolerances so tight! (you will be thankful after break in)
The trigger was weird on my gf's at first - started shooting full auto on semi! (Just needed use to break in the contacts)
I think that about covers the "weird" things that seemed like cons, truly, there are none.
I just installed a ball bearing spring guide and I anticipate a long fun life for this gun -
hope this was helpful!
