So these uppers parts kits include a lifetime, no questions asked warranty then?Those who have dealt with me, and a few people have, know that I stand behind what I sell and I contract with top names in the industry. There's something called a non-disclosure agreement that is pretty common in the industry and keeps me from mentioning names. Not to mention 90% of all manufacturers contract out for parts anyway. Unless you are buying from Daniel Defense, your parts are not made at the place you are buying them from. What matters is whether or not the company stands behind them and as people have said here, I do.
