Could this pass as a feedneck or is an accessory for a feedneck?

They say it's made to fit hoppers with no sanding. Halos and RLBs are the only hoppers that need sanding in standard sized feednecks. Chances are that this is a feedneck for 'Cocker threaded feednecks, and there is no need to sand down your Halo or RLB when using this.

If you arent using a forcefeed loader, such as a Halo or Reloader B, then it's good to have a high stack of paintballs, so that they will all feed right after eachother, and the higher the stack that you have, the fewers skipped shots. That's why if you look at older Angels from 5 years ago or so when all that people used were Revvys, you will notice that they have a very high feedneck.
