Well today started off wonderful I got out to the range early and got to testing my new bullets for my bulldog. I’m getting decent groups at 100yds and I’m really excited so I start ordering more bullets right at the range. I’m packing up and clearing my gun with the range officer and we both notice something on my bulldog that wasn’t there when we checked the gun in. My Pitbull mega moderator has a chunk missing out of the muzzle. So I start trying to think about what happened and I cannot come up with a reason why that happened. I didn’t notice any accuracy or noise difference through the day. Pitbull makes nice products I even have their single shot tray and it’s perfect. So fast forward to this evening. I’m watching tv when all of a sudden I hear a blast of air. My 70cu ft tank decided to decompress, so I run my butt out of the house with the tank to stop hurting the dogs ears and I let it decompress. I investigate the bottle and see the Oring where the neck and valve connect is bulging out. Not a good day fellas. Started out very well then went downhill. I emailed Pyramid Air and Pitbull Airguns explaining the situation for each issue I had today. Hopefully I get a response quickly tomorrow, I want to get back to the range ASAP. I can’t do much with my bulldog using a 90cu in tank at the range. Here’s some pics of my troubles today.
