So we know the gun is compatible with other brand cylinder which is good.

For some reason though my gun doesn't sound quite right when it shoots, I cant really explain it. Next time i test fire it i will record it and post up the video.

Ive installed madbull vtac extreme battle rail and it fits perfectly.

ive ordered a inner barrel and hop up as well as a lower power cylinder so i will be trying those out next.

ive heard that the A&K ptw doesnt like lipo batteries though, supposedly they over heat the boards? can someone confirm this before i decide to get a lipo battery or a nimh.

The issue i was having with the battery is that they werent strong enough to compress the piston. i either have to lower the velocity by changing out the cylinder or use a more powerful battery - 11.1v or more.
They are very sensitive to power spikes, the one I witnessed smokin was from a 14.8 Systema LiPo
