A while back I started building another AR for a long barrel build. When searching for a barrel, I was looking for something unique that I wouldn't likely see on the rifle's next to me at the range, but I didn't want to spend $400 on a barrel. That brought me to Red X Arms...they appear to have some nice and unique barrels and the prices are certainly good. The problem is with their service. Fortunately, before I order anything I'm not familiar with I try to do some research. I found horrible things about Red X, especially with the Better Business Bureau. It looks like they have quite a reputation for taking forever and/or not shipping products out, and they are plain rude. I decided to do a test of my own and email them with a basic question that I already knew the answer to and see how they would respond. Below is what transcribed. While not exactly a horrible response, it's pretty unprofessional and still pretty rude...they could have simply provided the answer without the smart-ass response. At that point, combined with what I learned from their BBB ratings, I decided not to purchase anything from them. http://www.bbb.org/minnesota/busine...red-x-arms-in-starbuck-mn-96318441/complaints ------------------- Hi, If you would have taken a minute to look at the website you would have found the answer to your question. I copied this from our warranty section under the terms and conditions tab at the bottom of the home screen. Only the use of SAAMI Ammunition is recommended and will be covered under the warranty. The use of reloaded ammunition will void warranty. Also the use of Israeli, Korean, Chinese, Potugese, PMP, South African Produced Surplus, Wolf, Norinco, Any Steel Cased, Lacquer Coated ammunition voids warranty. The use of the ammunition have been known to cause a range of problems and damage to the rifle/parts. They also may be unsafe to yourself and cause harm to you or others.
