Sweet rifle:
Lipo battery, new motor, upgrade spring, bit of a chop, a rail & aimpoint, silencer and a bit of paint...
A few teething problems to start though, flash hider crooked, would stop firing (fixed by rotating selector switch) but after two games, it has been humming ever since.
Lipo burnt out the factory motor, so a new one was added. New spring for some extra range.
L1A1 rocks.
