Very pleased with the MRP upper but just as pleased with the speedy ID verification and unbelievably fast shipping. This is my first purchase from RD and it certainly won’t be my last, fantastic company with excellent management/staff. Love the how they include the Constitution booklet in their shipments.

This is more of a review of Rooftop Defense than the LMT MRP-L 13.25 upper, because the upper is a typical LMT upper and we all know how top notch those are. Mine was the typical high quality you’d expect from LMT. This was also my first time shopping at Rooftop Defense and it was nothing short of exceptional. They verified my identity being that it was both a high-dollar purchase and my first purchase with them and within literal minutes I had tracking info and the upper was shipped. Lightning fast shipping and a conscientious owner who truly cares about his cause and customers. I will definitely be shopping here again. He even included a copy of the US Constitution and Declaration of Independence with the complimentary serving of Ramen. 10/10 experience.
