As such, I know NOTHING about the platform and was hoping you smart fellers could help a fellow enthusiast out with some basic AR101 knowledge.
I am pretty familiar with most rifles as far as operating and cleaning them is concerned, but I have never built a weapon from scratch, as it were.
I was hoping some one could explain the differences, or at least provide the links, to the different types of uppers/lowers/stocks/barrels/etc...

I apologize if this is a repeat post, I couldn't bring myself to sift through the swamp of pure information this forum provides...

Thanks again.

Welcome to our electronic campfire!

Welcome and rest assured, anything you could ever even think about concerning the 450 will be answered here!

Here is a quote from a previous post about building a lower receiver. The lower is pretty much a kit project, once you have gotten the required parts and a few tools. From what I have seen on YouTube, building the upper requires more "gunsmithing" skills and some additional tools. The quote below is from this thread, http://www.450bushmaster.net/viewtopic.php?f=2&t=47&p=27133&hilit=lower+build+mako+gl+shock#p27133.

"Just completed building a lower for my 450. If anyone is contemplating doing this, PM me and I can send you a list of the parts you will need. Building the parts list was one of the harder aspects of doing this. I undertook this because I wanted some custom components, so I ended up with the following:


Tactical Innovations stripped lower (Tactical Innovations)
DPMS / Panther internals (Brownells) and buffer assembly kit (DPMS)
Magpul trigger guard (Midway)
Mako GL-Shock butt stock (Outdoor Oasis)
Mission First Tactical G-27 Tactical Pistol Grip (Midway)
Geissele two-stage trigger group (Midway)

I could have saved some money by shopping more widely, but the prices at Midway and Brownells were competitive. Also, Brownells sells an internal parts kit without the trigger group or pistol grip, which I planned to buy separately. They also have a set of instructional videos at http://www.ar15builder.com that were invaluable. The trigger group ran the price up to just south of $525 including shipping, and I also invested about $100 in tools (roll pin punches, pivot pin detent tool, AR15 combo wrench to tighten the butt stock, lower receiver vice block, etc.), since this was my first build. It took me about 6 hours to put it together, excluding time spent searching for the take-down pin detent, which launched itself into outer space during assembly. Yes, you could buy a less expensive lower with stock parts.

The upper is stock Bushmaster 450 with the addition of a Harris 9 - 13" swivel bipod, Butler Creek sling, and a Sportsman's Guide (I think Barska makes it) 3-12x50 scope on a UGT riser."

This is a link to a different site, but might be what your looking for.

These are great written instructions. I wish I had that parts and tools list, when I started. If you want to see one go together, step-by-step, check out the videos as http://www.ar15builder.com/.

I've built two stag arms lower so far and I am very glad that I invested in my bushmaster assembly video. It really helped.
