I have the craving of building an M4! So, I've been researching this site looking for the in's and out's of affordable and quality parts. Here's a list of what I'm thinking of getting... does anyone see any foreseeable problems with any company and/or product I might use?

Stag Complete Lower (factory installed)
Del-Ton 16" Chrome Lined 5.56 w/ M4 feedramps and w/ Chrome Bolt Assembly
a 9mm heavy buffer from ? (maybe RRA)
ACE SOCOM M4 Stock

Reasoning: I hear the Stag lower is very well built with little "play" between it and the upper. Del-Ton seems affordable and I love the options it gives. I've read on this site that the 9mm heavy buffer reduces recoil, and the ACE stock has the "look cool factor" and I've read that it's strong.

Thanks.
