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: Great gun light shoots great plenty of power . I get tight groups .has a great feel ,it's not quiet tho .itll put a pellet through 1/2 inch plywood I'm very happy with it .

Things I would have changed: The reviews I read that the scope mounts were weak ,so I went ahead and JB welded the rail and mount to start out . Let that dry for 48 hours .im using the cheep scope but everything has held up

What others should know: It's a $200 gun well worth the money some ppl review likes it's a $600 gun . Clean the mount area and mounts with alcohol very well glue them on with JB wait for that to dry well(like 48 hours ) n you will love this gun don't glue the scope just the mounts

Things I liked: Love the feel of the gun... Hits what i'm shooting at really hard...

Things I would have changed: Rails,mounts, scope.... I'm like all the others. Can't keep a scope on it... The scope that came with it lasted 10 shots before the elevation and wndage knobs quit working. Put a 3-9X40 on it. Was deadly accurate for a couple hundred shots, then the same with it on the windadge and elev. also the zoom quit zooming. Was stuck on prob 9X. Bought another new scope a 4-12X40. Have no probs with it yet (YET). Have prob. 800-1000 rounds through it now with the new scope and its been flawless so far. Keeps tight groups @ 50yds, like inside a 50 cent piece which is good enough for me anyways. I do get the accasional flier as to I dunno where the hell it went pellet.

What others should know: Not very quiet, but its ok. UNTILL you use PBA ammo then Daaaaang the thing come to life. But mine doesn't like the PBA non-lead stuff tho. Very unaccurate and LOTS of fliers. The best pellet I found for mine and it holds the tightest group are the Gamo Red Fire pellets. I have the .177 cal by the way... I was wondering has anyone tried foaming in the butt stock to see if it makes it any quieter???? I think if maybe ya take the hollowness away from it it might be quieter and not add weight., Just a thought...... P.S. with the PBA ammo I cant even get it to group enough on a styro plate at 15-30 yds at all :-{ Overall this is an AWESOME and sweet gun to shoot. Just an optics, mount setup will have going bonkers until you can figure out how to keep it still or not destroy scopes... I truly do love my Gamo Bone to pieces... Hope this helps and I can get feedback from some also... Thanx

  • Ahmed from USA asked:

    How much is the shipping weight

    • Ahmed from USA asked:

      This gun says is it refurbished. Exactly what is it they have refurbished? Are these guns second hand? And how much is the shipping weight ?

      • Rocky from USA:

        It does not mean that it is second hand in the sense of used , most of the time the rifle was sent back as the person did not like it. Some have an issue that is fixed and they can't be sold as new so they are sold as a Refurbished .

    • micheal from USA asked:

      what is the best pellet for this?

      • Michael from USA:

        Try jsb jumbo heavy, H&N Barracuda Match, or RWS Super Dome.
