Ok so I bought this gun and for the most part I love it. I only have one problem when I fire it on semi- auto the trigger sticks after every shot and you either have to pull the charging bolt back or tap the trigger to get it to reset. I have looked in several places and the only advice I got was that the hammer bearing might be sticking. But I never got a clear description of what that was so I think its ok but im not sure and I was wondering if it could be something else.
