I am looking to make a warpless Halo. Loader mounts on the side of the gun as opposed to the top and feeds via hose.

However, I know nothing about the current hoppers out there. I am looking to buy a used Halo but dont know what type I need. I see that Halo seems to have been bought by Empire?

How do I tell if the hopper is eye vs sound activated? I assume I can't use an eye activated hopper for the warpless mod?

Is there a better loader out there for this?

Thanks collective brain trust!
