Mil-spec seems to be most common so...

I ordered a Magpul CTS butt stock and AR Stoner buffer tube assembly, both mil-spec, the CMMG parts kit and Daniel Defense has an over-molded pistol grip with the rounded trigger guard integral to the grip. That should cover everything except a spanner wrench and the parts kit doesn't come with trigger guard roll pin. With the DD grip/trigger guard I don't need a roll pin but I would think I need the front pin and tiny roll pin that holds it in. I don't think that comes with the DD grip or my parts bag and I can't find it for sale at Midway. I may have to order the front trigger guard hardware from Brownells if it doesn't come with the grip. Other than that I should be set.
