So, when I decided which rba to buy I was planning on building my own bottom feeder and settled on the A7. I lost my work shop as my wife decided to turn it into storage and ordered a Vmod instead. I just discovered the Vmod is designed for cartos to be recessed into a collar that's too small for my A7 to fit into. Just wondering if anybody else has run into this issue and how you resolved it. 510-510 connector maybe? Removing the collar and bringing the 510 connection up higher on the mod?
