Microbest DLC BCG
The review is early because the bolts are unfired. The parts hold very tight tolerances and the finish is smooth as black glass. Both headspaced appropriately. They will contain pressure and reduce maintenance as they should. Thank you to Arftac for inventorying this product..!

2nd MB dlc
2nd review here. Bought another MB dlc bcg for another rifle. I cant overstate how slick this dlc coating is. Blows the toolcraft dlc out of the water. Whoever is doing this coating is really good at polishing/tumbling etc. I was surprised by the carrier key alignment too. Arftac nailed that. The gas key on the bcg that came with my DD scrapes the gas tube. Arftac took great care in making sure these gas keys are perfectly aligned and make zero contact with the gas tube. Both of mine are absolutely perfect. Next plan is to send one off to SOTAR and I guarantee it'll pass with flying colors. These are absolutely the best bcg on the market right now, and at such a steal of a price

Excellent
Great fit and finish. Feels like it's oiled when it's dry, almost shocking looking at your hands expecting residue.

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!
