An Air Propulsion System is an essential mod for your Utility Barrel. Not only can it fire much more silently than a typical propulsion system but it can fire delicate items such as a grappling hook without damaging them. Turning the crank on its side activates a carefully crafted set of gears and cups that trap air and compress it, pressurizing the chamber to be fired. If you are planning on scaling a wall anytime soon, grab yourself an A.P.S., grappling hook, Utility Barrel, and fire away!

This under-barrel mod fires projectiles with the same loudness as a bow and arrow and can be fired underwater. Ranged attacks made with this weapon have a 30 ft penalty to their normal range. In addition, it does not damage the ammunition it fires. Your firearms reload is changed to 1
