AR Lower receiver parts question...

I'm building a new lower receiver and I'm about to buy the rest of my parts. I would appreciate any advice on parts before I buy. It's a Spikes lower and I've already bought a Geissele (SP?) SSA-E trigger. Midway has a CMMG small parts kit without trigger for under $50 and it says Milspec. I would guess Milspec is Milspec. I plan on using the Magpul telescoping butt stock that locks in place...don't remember the model number. I'll either use a Magpul or Ergo grip. Need to know whether it's better to go with a civilian or Milspec buffer tube and if the CMMG parts kit sounds ok. Any other advice welcome too. The only thing written in stone is the receiver and trigger. Gonna be for my 16" .223/5.56 carbine for now and later I'll build or buy another upper for this lower and put this upper back on the lower it came on. Thanks, rob
