Here are the benefits of the IGT over a metal mainspring:
Gamo has entered the field of gas pistons with a Whisper! The Bone Collector Bull Whisper IGT air rifle is not only incredibly powerful, but it has many special features that'll set it apart from ordinary breakbarrel rifles with regular metal springs. Their proprietary gas piston means you can cock the gun and wait to take your next shot without worrying about a metal spring taking a set or weakening. Gas pistons are robust and do not lose anything in either area. Plus, gas pistons are known to shoot MUCH smoother and deliver less twang and vibration to the shooter!
Let's talk about the Shock Wave Absorber recoil pad. There's an entire industry centered around making aftermarket recoil pads. Their intent is to reduce the felt recoil, because constant recoil pounding into your shoulder is painful and will stop you from shooting as much as you want. While the gas piston is going to seriously reduce the vibration, the SWA recoil pad will stop you from feeling most of the recoil from the remaining movement of the gun.
In the past, Gamo customers have swapped out their triggers with aftermarket ones. No need to do that anymore! The Smooth Action Trigger is light years better than the previous version. It's smooth and predictable. What will that do for you? It'll improve your groups. Unpredictable and heavy triggers or triggers that don't break crisply are often responsible for delivering larger groups. You'll be amazed at how good a shot you are when you shoot the Bone Collector Bull Whisper IGT air rifle!
