Our sincerest apologies for the email overload. We obviously want to make sure the emails we sent out are meaningful, and this is something we are taking very seriously. If you could please message us with your account information, our web team would like to look into this further. They are currently out of stock and I do not have any re-stocking dates at this time.
I also wanted to provide some clarification on our cam pins. The H13 Cam pin comes in two different styles, but both are the same material/finish. REBCGS that come in our Super Duty uppers, rifles, and pistols will all come with a beefed up Cam pin. It has the laser engraved arrow, but the outboard side of the cam pin is raised and enlarged. This mates with the cut out in our Super Duty Upper Receivers. By having this enhanced Cam pin, it permits more even wear over time and aids in cutting through carbon.
But do you need this cam pin in your Super Duty if it were replaced? No. You can substitute it for any Mil-Spec cam pin and it will function. You cannot take a Super Duty REBCG and place it in an upper that does not have the Super Duty upper cut out. Swapping the cam pin will again remedy this.
The REBCGs sold on our website as a standalone item, will have an H13 cam pin that is Mil-Spec in geometry so you can use it in any upper. Although we do not plan on offering the H13 cam pin as an individual item, it is something I will pass on to our project teams. I hope this information helps and I will make sure I’m available to answer any additional questions.
