Yes, I think they bought BHW.
Ah, i see.
Regardless of what their quality might be, I think this stands as a good example of the "law as written" in practice.
And mind you, the 16 inch "Hybrid Profile" Criterion barrel is just over 2lb, less than 1oz less than a 16 inch carbine gas heavy profile that I have on another build. Hardly a lightweight to begin with.
