Rev, the R51 had a multiple amount of issues when first released to the public. Remington actually pulled it from the shelves of all gun stores after the issues came to light. The most damning problem was that it would fire out of battery, yes, out of battery, resulting in a badly bulged or ruptured case and a possible injury (or death) to those that either shot it or happened to be around the person shooting it.
I think it may have been the worst start of life of any gun that I have ever heard of.
