FX Bobcat Air Leak

[cj_86]

I have a .25 FX Bobcat and every now and then when I am shooting on the bench I feel a puff of air hit me in the face. I've never had a problem with accuracy and the gun shoots great ,but I just wanted to know if any other users of the Bobcat have experience this? The air seems to be coming from the power adjuster wheel area I think? Just wondering if this is normal.


Thanks,
CJ

Maybe o ring issue.

it's the o-ring at the barrel breach. I had mine do that a few times, then the o-ring came out. I put it back in and no problems since.

I just checked and the oring is in the breech. I also removed the oring, inspected, and it seemed to be in good condition. I lubed the oring with light silicone grease and reinstalled it.

Shot string seemed consistant with 10 fps spread with the small puff of air. It's weird and I just thought that's how a regulated gun functioned?

I found more information on the forum. I think I will order some extra o-rings so I can keep them on hand. Also, someone did mention that the power wheel may release a puff of air too. Thanks for the help again guys.

You also should put whatever oil you use on there. just a tiny drop.

Silicone Grease is best for o-rings.

On earlier variable power FX rifles the power wheel worked by changing the size of the transfer port which was sandwiched between two O-rings. If either of the O-rings is leaking then you'll feel a puff of air when firing.
