A customer recently purchased a high quality Bolt from us. Today, he sent us an e-mail stating that he was unhappy with the Bolt's quality due to the fact that he could not get a Cam Pin to pass all the way through the hole in the Bolt.
In order to "Fix" the problem, he took a Dremel tool to the back side of the Bolt and opened it.
Before you try and "Fix" a problem, please make sure you know what you are talking about FIRST.
