They said they answered 300 voicemails in ONE day...sounds like they may be a little backed up from the holiday, just like most companies are (I cleared about 300 emails yesterday!!!)

I'm sorry, but what are you expecting from them? An answer the instant they get it in the mail?

The delivery companies run people hard leading into the holidays, and often packages take LONGER than normal to get delivered after Christmas as a result. I ordered a couple things by internet recently and they took longer than normal to arrive despite being shipped the next day. They may not have even gotten it until a few days ago!

You sent it in during the holidays, like a week ago, and expect an answer already? They may have a good turnaround but honestly you are being unreasonable with them. Despite that I bet they will replace your barrel and make things right.

Ease off on the instant gratification. If I recall I sent them my gun during April or May, likely the slowest time of the year for them, and had it back in about two weeks. I had no issues with that.
