Holy cow. A visual inspect at the factory or retailer could have caught that. Is it just me or do PCPs seem to get better quality control attention than springers do? I've heard great things about the D48.
A Diana 48 is my dream airgun. Thank you for sharing about 4 out of 5 of your guns being defective. This would make me invest in PA's 20 shots for $20 to catch something like this whenever I decide to buy. Does AoA have a program like this as I am not familiar with them?
Sorry to hear about the condition of your new 48I'd send it back also. On another note though, if you can get a good one you'll love it. I have two 48's (.20 cal and .177) and I just love those guns to death. The feel, the balance, the accuracy, the power and of course the look. Picked up a 54 last year in .22 and that rifle is just amazing. Can't say enough good things about my 48's so I really hope the next one you get is perfect. Jeff
... I'm not complaining about AOA Im just disappointed in Diana
...send it back and get a replacement. Jeff
