this is a Great lipo tube! Has a very nice finish and the castle nut is actually a separate piece that screws on to the
threads. Fits my tenergy 7.4 volt 1000 mah batteries pretty well , though you do need to pay attention when making
a wire harness for the tube.
light weight but very solid
Castle nut is separate
HAS 7 POSITIONS for a finer adjustment
fits lipos well
Fits mil spec stocks
Now this isn't really a con just some thing you need to be aware of
- you need to trim off some of the stock post on your lower receiver so the tube will slide all the way on.
i just used a hack saw.
