Question: What is IGT
Document: Hi. I have a black ((Bull Whisper Extreme.177)) that shoots 1400 fps with PBA. ((It is not the Bone Collector model. ))It does have the same barrel though, and it is a little louder than my RUGER Air Hawk .177, Which sounds like a construction nail gun. The BULL WHISPER EXTREME has a more solid POW sound but not too loud. It is a Spring piston model and not the IGT piston.
I needed an upgrade to my Gamo Silent Stalker IGT .177 and saw the excellent reviews for the Bone Collector in .22. And to my excitment, I saw that it was now offered in IGT as well. As sooon as it arrived, I quickly put it through its paces and to my chagrin, it was as loud as my "Silent" Stalker and kicked just as hard to boot!I paid about $220.00 for this rifle that was supposed to have the extra bells and whistles.
I bought this gun at Walmart for cheap. Mostly for the IGT (gas piston), the Smoother 2 stage trigger, which is awesome, and it's low noise profile, another win. So let's cover the positive first.UPDATED: Leaving original review intact, this paragraph will encompass the change from 3 to 5 stars. The gun had horrible accuracy as mentioned below, and not willing to give up another reviewer on some site had a similar problem. They solved by using a barrel cleaner.
The original scope lasted several months. Bull Whisper Extreme does have a 41lb cocking effort though to power through 1400 fps. But my 11 year old boy can operate the cocking mechanism and fire it over and over. The Bone Collector model IGT Piston has a 30 lb cocking effort to power the 1300 fps.The stocks are quite different and more like a competition rifle.It is very BALANCED and Fairly light. The plastic of the stock has excess lines on it from being formed in two half molds.
The Gamo Bone Collector Bull Whisper IGT Air Rifle is an excellent choice for an affordable, powerful, adult air-rifle. Also recognize the scope and mounts will probably not last that long but the quality of the rifle is high given the affordability, I purchased this rifle knowing I would upgrade the scope and mounts and still viewed thie purchased as being a great value. This rifle is very suitible for pest control. I cringe when I see all of the negative reviews about this rifle being loud.
when I got the box, it was all broken up and the gun was half hanging out. the gun itself was quite load. I just never had a good feeling about this so I returned. sorry, nothing against amazon but I would have expect gamo to step up their game if bone collector was going to put their name on it.
swap out the scope and throw the gamo scope away. I use a center point 3-9x40 with awesome success. accurate as hell
not very accurate gun. oh I bought a 22 cal,
my first one ordered in oct had to be returned, got the replacement in nov, two scopes and two mounts later still not able to put 6 rounds  in the bottom of a coffee can at 60'. My brother got same gun very recently and had to send it back because the barrel fell off! fortunately he ordered from Midway and had no return problem, I ordered from amazon and they are not so concerned! &#34; Team Gammo &#34; must be shooting another brand !
it is truly a quality made product, all you need to do is order some dove tail to weaver rail mounts and a new scope with it and you'l be all good.
