I am interested in building a 375 Raptor. I see currently Brownells is selling an Aero lower for $99.99 on sale and wasn't sure if I should just go this route and then source the components separate or if the SP10 kit from Seekins would would work for this. I have built some AR15's with complete uppers but I would like to build from 100% ground up. Build list is below for what I am thinking. This will be the first from ground up and I am open to suggestions.
