Trying to identify .450 Bushmaster upper manufacturer(s)...

[KennVFRidr]

I have an unidentified .450 Bushmaster upper and I'd like to figure out the manufacturer...or at least who made the barrel??? Might've been purchased from Delta Team Tactical in Florida...

16" carbine, Aero Precision XL upper receiver, heavy barrel 1:24 twist, barrel extension to gas block barrel diameter 0.983", gas block diameter 0.875", gas block journal length approximately 1.86", journal to barrel threads diameter 0.867", unknown flash hider, unknown hand guard.
