Great customer service. - Radical Firearms 16 in. 300 AAC Blackout Upper Assembly

I have purchased numerous items from Optic Planet. Their prices and delivery are better than most. My grandchildren gave me a 300 Blackout upper for Christmas. I had to remove the flash protector so I could legally bring it to my vacation house in New York. When I did so and attempted to clean it for the first time, I discovered heavy rust in the barrel and chamber! I called Optics Planet and they agreed to replace it without question even though I had damaged the flash hider taking it off. I was very impressed by their customer service. I will update this review when I get the new "Rust Free" upper.
