Great finish
Replaced semi BCG with this, works great on testing with frt 2 mags, went to clean post test shoot and wipes off carbon no problem. Very slick

Arftac+microbest+DLC= win
J Cade was an absolute pleasure to talk with. Answered all of my dumb questions. Bcg itself is incredibly well made, super slick, and QC'd very well. Such a great buy, and from my new favorite store!
