BCM "Large Stock" upper receiver?

[PrivateCitizen]

I just ran across this …

This is the first time I've heard of such a thing … or are the copywriters at OpticsPlanet just clueless?

Bravo Company MFG 4-Ur-M4 Upper Assby Flattop M4 Large Stock Model

Is this a regular upper or something new?

Nevermind. It seems Optics Planet just cut/paste a bit of web copy.

The "LRG-STK-MOD" is actually a BCM SKU for a completed lower.
