Hi, I just bought my first Excalibur crossbow, the Phoenix. I have just shot it 4 times with a 20 inch, heavy weight, aluminium arrow and everything seemed fine. I then noticed a couple of strange "cracks" on one of the limbs but I'm not convinced they are cracks and could be just the camo coming away and revealing indents in the limbs. I'm fairly new to crossbows so I don't know a lot about them.
Should I be concerned?
