have one in 224LBC which is the 22ARC, absolute tack driver with top notch craftsmanship. mine is on a Shilen blank don't know what blanks he is using now but highly recommend.
I have a Rem 783 - 284 Win. 8 twist profiled and chambered by Antony. Great shooter, very pleased and I will use him again. I think this one is off a x-cal blank if my memory serves me correctly.
I have several barrels from Anthony. All are .5 MOA or better than I can shoot. He even chambered a Proof barrel back when he was still chambering customers barrels. Great work, communication and quick work. His video on setting headspace is worth a watch.
I have had a few and never had any complaints. He put the wrong fluting on a barrel I ordered once and was very fast to make it right. I haven't ordered one from them in a while but they were usually very quick turnaround if they have the blank in stock.
He put together a "Howage" for me in 223 AI custom throated for 75g ELD's. I was a little skeptical about the X-cal barrels he was using at the time but very pleased with the outcome. I bore scoped the barrel on arrival and the chambering work was exceptional. Gun easily holds .5 moa with hand loads and has shot in the .2's. Great communication and fast turn around, price was great too. Highly recommend.
