A year or so ago during the looming gun legislation, I jumped on purchasing a Del Ton lower, several aluminum mags, a decent trigger, lpk etc. Due to the price of parts I put the build on hold and would like to proceed.
My question is how important is it that I purchase an upper from Del Ton? I'm looking at purchasing a complete upper build because I don't have the tools nor do I trust myself

.
Great information and thanks in advance.
