Fcd buffer retainer detent - Forward Controls Design AR15/AR10 Buffer Retainer

When it comes to building a quality AR it comes down to the finer details/parts like this FCD Buffer Retainer Detent. I put this in one of my high end builds and while I may not notice some kind of improvement, I do know I have quality parts like this detent that will out last your standard mil-spec version. If you place value in the finer details and parts in your build then I would highly recommend getting one of these.
