I have two 995ts that I picked up this week. They are brand new and sequentially numbered so I suspect they were manufactured one after the other. When I put a mag in the well, I cannot push the mag release without having to push the adjustment tool in. Once I do that, the mag pops out as expected. The little metal button is recessed and I can't push it in with a finger. Both carbines are the same. I expected the larger button around the small metal pin to move but it is firm and stationary. Is this normal?
