Maybe I did n't make my question clear I was wanting to see whether the top cap is a Hybrid which is a direct current to the battery, or one which has a floating center pin which both can only be seen by taking the top cap off.
And as far a the fire button I just wanted to see if it is a spring or magnet or a button that has no locking ring which would have to be tighten by a screw inside! I hope this is a better way for you to understand what I'm asking. Thank you!
