Warning bad business - Faxon Firearms 300 Gunner Rifle Barrel

I heard some of their 300 barrels had gas port issues (to small) I contacted the company (they are local) who said it was a known issue that has recently been corrected. They further stated if I placed an order and received an older version to bring it by and they will fix it in about 5 minutes. No surprise once I received the barrel I was told I could not bring it by. I will not be doing business with this company again. It’s a shame I try to support local business
