Customer service
Asked for an exchange on the carrier because I thought there was a small nick, without hesitation he mailed one out with a mailer and more treats. Truly the best customer service!

Quality BCG
Awesome BCG gauges out perfect with my Faxon Barrel. ARFTac is a great company to do business with.
-
Microbest Chrome is great!
Great staking job. Chrome holds lube and cleans easier than NiB. That phosphate extractor isn't the prettiest, but I'm down with function over form.
-
Really solid performer
So far so good! About 400 rds in without a single failure. Cleans up easily, looks great, and parts seem to be well built.

Hit and miss
The first couple were not to my liking. ARFTAC was great and exchanged them quickly, with much better replacements. Great vendor!

Microbeast Chrome BCG
One of the best bcg's out there and an incredible price through arftac. If your running cheap nitride or no name nib bcg's stock up on these as replacements while they're still available at a very reasonable price.
