I got a PVD Titaniumnitride coating for my barrel extension:
I got that for all my ARs. If you know a small manufacturer ask them to coat the barrel extensions this way!! It really improves the barrel extension! The cleaning is 100% improved due to the no-stick feature of the Titanium.

I pay attention to details,...
