Manufacturer response - TRYBE Defense Mil-Spec Nickel Boron Coated Cam Pin

I wrote the earlier review about using in 7.62x39 and it not fitting, and received this response from the manufacturer. While I still would not buy knowing what I know, I am improving the rating,as they are correct, I'm not using in Mil-Spec, even though all the parts on the BCG except for the bolt are otherwise milspec. I have no interest in throwing anyone under the bus, only like to relay my experiences, which is why I'm posting this follow up...

"The cam pin is meant to fit any standard mil-spec bolt carrier and standard mil-spec bolt. Unfortunately there is no way for us to guarantee perfect fitment with parts that are not mil-spec like a 7.62x39 bolt. As long as the bolt followed mil-spec specifications then it should have accommodated this cam-pin. This was information provided to us by our product engineers:

“We’ve sold thousands of cam pins and that’s a first for us (i.e. Never heard of this issue before). Our cam pins are designed to work in MilSpec 5.56mm, .223 and 300 blackout configurations. We can’t guarantee it will work with non-MilSpec carriers with other calibers, such as 7.62x39. In fact, shooters often speak of needing to modify the cam pin in situations like this. We will always guarantee our parts for MilSpec 5.56mm, .223 and 300 BO configurations.”

As stated before, once I learned it was not suitable for my application I returned the part, so other than testing against two 7.52x38 AR-15's with different brand BCG's and finding neither played well with this Cam Pin, I returned it. I appreciate them taking the time to respond. I would not avoid them because of this small matter.
