I was wondering if I got this drop forward/ on/off will I be able to fit it with my 88/4500 HPA tank on my ion. I dont have the tank yet... it is in the mail. or else i wouldnt ask this question.
It should because the only part that should become of the drop would be the reg.
I wouldnt recommend a drop because it gives most people a bad shooting stance/form. Most of the time, you will see people with their arms sticking way out that have dropforwards.
