What stripped lower would be the best starting point if I ever decided to sell my build? I typically don't sell any of my weapons, but if I ever have to I want to get the maximum resell value. I'm familiar with the AR platform and have a 6920. I'm only interested in forged. I only plan on using top tier internals and a top tier upper, so I'm only looking for advice on the stripped lower. Thanks for any help you might be able to provide.
