hi, three things- if u fitted an on/off switch to a 2000 shocker, where would it actually be fitted on the gun? secondly, is puting a nine volt battery adaptor onto a shocker 2000 as simple as soldering the adaptor on-ie, u don't need to worry about voltage conversion or any of that, and finally is it possible to get a 15 degree asa for the old style beast? your help regarding these queries would be much appreciated. thank you all in advance
