    Customer service

    Posted by Stephen Simon on 5th Sep 2023

    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

    Posted by Chaz on 18th Jul 2023

    Awesome BCG gauges out perfect with my Faxon Barrel. ARFTac is a great company to do business with.

    Microbest Chrome is great!

    Posted by Dan on 6th Jul 2023

    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

    Posted by Brad on 28th Jun 2023

    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

    Posted by Jeff on 31st May 2023

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

    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.
