BCM spare assembled upper conundrum

[TheRifleman]

I came upon some parts a few months ago. A QRF 12, 14.5 BFH EL P&W to a SFMB, and a BCG. All BCM of course. Previous owner was clean and said it was at least 2,000 between the barrel and bolt. Not a big deal, especially for what I had considered to be spare parts.

Months down the line, the QRF was traded for a BNIB MCMR13, last night I thermally fit the just arrived blemished BCM upper to match the used "patina" of the barrel and BCG, and this morning I logged into my BCM account and started adding a cam pin, retaining pin, replacement extractor kit, and a firing pin into my cart to save for later.

And now I'm totally not thinking of asking my FFL to order me as assembled BCM lower with PNT and the SOPMOD Mod 0 stock. WTF is wrong with me here??? I just wanted a spare assembled upper for SHTF replacement emergencies only.

Oof. What would y'all do?
