X-Caliber 45 ACP Barrel, new build, etc...

[Little Dutch]

I bought the upper from 00tec last week. Here's the link to the upper:

It appears to line up perfectly with the New Frontier lower, and may be made by New Frontier (Or made by whoever actually makes theirs).

The Moriarti lower I linked above looks exactly like the New Frontier lower, and I suspect they are probably the same lowers with different roll stamps. I like the Moriarti rollstamp better so am going that route.


ETA- I went and looked at the Gibbz uppers, they certainly have a unique look. Pretty cool.
