Air Venturi Power plenum

[moneypitnotosowner]

My Avenger in .25cal has a power plenum i installed on the side. Works AMAZING!
My question is, can I put on the other style plenum that goes under the rifle as well and will it be safe??? I have the one on the top but I was wanting to add the shorty on the bottom

isn't the avenger regulator gauge on the other side? plenum needs to be regulated air, not reservoir air.

To answer your question, it shouldn't be a problem. You're just giving the gun more air to push through the valve on a shot cycle.
