I picked my SR-15 today and was giving her the once-over. In the up position, there is a significant amount of fore-aft and side-to-side movement--best described as "rocking". It is almost as though the hole that the spring-loaded pin goes through is oversized. I can't believe this is normal for this product since everything else on it is solid as a rock (and it cost an arm and a leg).
Any information or experience appreciated.
