We put the low in our lo rize. The
lowest one you can find (Halo version). Whats this mean? It brings your hopper
much lower to make you and your marker less of a target. Ideal for all players.
The top row is for universal hoppers or VL Revolutions while the bottom row fits
only the Halo force feed system. They have 3 grooves inside with o-rings that
provide that added grip.
