So far, I've got a new DD 10.3" barrel in 300blk and a really funky looking lower with finger grooves on the magwell that I received as a gift. I may get a more standard lower later on. I plan on using a Thordsen buffer tube cover on a keyed carbine buffer tube I have.
What parts from here on out would highly recommend me using (as in a specific upper, bolt, gas block, rail, muzzle device, etc...)
A suppressor may be in the future later down the road.
