Thanks. That's good to know. The Super Colibri is also pistol only, but I have shot it out of lots of rifles. It is more quiet than my .22 caliber Benjamen air rifle with 10 pumps! Dang, that is nice. However, this is not recommended and I do NOT recommend or encourage any out there to try that with their own rifles. Yadda yadda yadda. I have experienced NO problems yet.Raider said:KJUN, I just looked. Guess I have the old. Just says Colibri. 20gr bullet, no powder. Its literally quieter than my pellet rifle out of a Ruger MK2 pistol. Its extremely accurate at 15yds (far as I've tested). The super is a little louder but not enough to rouse people 20-40 yds away IMO.
