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 Custom Action Trigger is light years better than the previous version. It's smooth and predictable and allows you to tailor the trigger to your personal preferences. 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!

Things I liked: This is a handy rifle its light especially compared to the rws 48 and hatsan torpedo 100x I like the new trigger miles better than the old gamo trigger easy to cock mine liked the gamo redfire pellets which was kind of odd because no other rifle I own did the stock is nice and it is quiet whether do to the whisper technology or not I dont know but much quieter than the hatsan

Things I would have changed: I think all air gun manufacturers should swiyvh to weaver rails instead of dovetails but I use adaptors and jb weld them into place and has worked great I don't see a reason the rail would ever have to come off so works for me

What others should know: The cocking weight is light the rifle is light great rifle for all day hunting and taking off hand shots I recommend this rifle as a great first rifle or even just another to add to the collection

Things I liked: Break barrel is easy to manage, light weight, recoil reduction is awesome, safety trigger is convenient... Overall, worth the money spent.

Things I would have changed: Have it come with a better scope

What others should know: The silencing system doesn't really seem to make much of a difference

Verified Purchase

Things I liked: this gun is stable to shoot. 1300 fps is very healthy.the gun feels great in my hands and cheek rest is perfect.the break action is strong.

Things I would have changed: the Gamo scope that comes with gun is junk. my value rating is only 3 stars due to needing to buy a new scope of better quality which increased my cost by $100.00 to $279.00

What others should know: don't forget to order pellets with your purchase.

  • David from USA asked:

    I've had my bone collector now for almost a year I've noticed the cocking effort has lighten up does this mean i'm slowly losing power or is this normal can't really tell if there was more power before i notice this happening.

    • syed from USA asked:

      which is the best pellet for .177 cal, preferred for hunting small game

      • Stanley from USA:

        You could try the crosman 10.5 grain dome , they work very well in my Hunter Extreme ? Usually heavier pellets work well in magnum springers and gas piston variants.

    • Ahmed from USA asked:

      How much is the shipping weight
