I have a brand new Gemtech Suppressed Bolt Carrier GSBC-5.56 that I purchased a while back but have never had a chance to use before. I am trying to install it into a mil-spec upper receiver and it cannot go in. The valve flange that is used to switch the mode from suppressed to unsuppressed seems to be sticking out a little bit too much (maybe by 1/16") and it hangs on the side of the upper receiver preventing the bolt carrier from going in. The valve is very easy to take out and put back in. So, I have tried reseating the valve several times, and the valve is definitely fully seated and cannot be pushed in any further. I tried several different mil-spec upper receivers - and the result is exactly the same. It seems to me that the valve is a little bit too long. I wonder if anybody has faced this problem and if there is any way of fixing it.
The problem is that Gemtech has been bought by S&W and the current Gemtech support is not in Idaho anymore, but just regular S&W support in Springfield, MA. This suppressed bolt carrier seems to be discontinued - no traces of it on the Gemtech website. If I am correct that the valve is out of spec, then the only remedy seems to be to replace the valve. I called Gemtech tech support and got some S&W people who know nothing about this product and cannot tell me if repair parts are still available. The only option they offered is to send the bolt carrier to them at my own expense, and then they will check it, and if they do not have the parts to repair it, they will return it to me. All my pleas to check if a replacement valve is still available were to no avail. I would appreciate any help.
