The Proto Primo Loader does not require any batteries in order to feed paint. The unique spacer just above the feed neck pushes paintballs to the front and back so you are essentially feeding paintballs twice as fast.

The Proto Primo Loader is powered by minimal agitation of your paintball gun. The Proto Primo Loader helps to sort and funnel your paintballs so you have a consistent feed of paintballs.

This version of the Proto Primo loader is the first of its kind with a positive feed shelf built in. This is there in order to relieve pressure on the paint which allows for an increased feed rate and less jams.

The standard Proto Primo loader comes with a clear spring lid so you can easily reload your paintballs in a hurry. This version has a large capacity shell and holds about 200 paintballs when filled to the top.

Overall, the Proto Primo loader is a great and low cost alternative to some of the more expensive electric loaders that roughly feed the same balls per second.
