Hey guys. I picked up this rifle over the weekend at the local gunshow. I haven't had a chance to shoot it but was wondering if there was somebody out there who has or has had one of these. It has 4 different front sights that slip into place. What I don't understand is that when the front posts click into place, they are not centered on the barrel. Is this just how it is, or do I have to center it myself between slots?
