Thank you for stopping in and being patient while we try and dance around the rules at YouTube. For an up to date list of what is available at PSA for blemished products please follow this LINK.
A blem can be something as simple as a scratch in the finish of a lower or even a dent in the metal hand guard. A blem from PSA will never be functionally defective and will always have the same warranty that every other firearm they make has.
Save some money and check out the blem section at PSA today. You just might find a few items discounted so heavily you cant resist ordering them
