    10.5 blk out upper

    Great quality and shoots well so far. Only 100 or so rounds but it fits great to my Anderson lower. Also great customer service. I will definitely do business with them again and spread the word. It’s a great setup for the money.

    Couldn't be happier!

    Got this 10.5" 300 BLK barreled upper to add to my to first ever lower receiver AR build, and it turned out great! Used a BN Lower parts kit from y'all with an Anderson Lower receiver. All fit together perfectly! Definitely the best priced barreled upper receiver you can buy anywhere! The upper comes completely assembled and was put together perfectly and shipped damn fast! I was surprised with the quality and finally went to shoot it last week and everything was perfect! After aligning my new sights, accuracy was very consistent. Was easy to attach a fat silencer as well and all functioned beautifully! Thank y'all so much for offering a great product at a great price!

    Highly recommend

    this upper is Amazing got it in record shipping time. Took it to the range this weekend and was extremely reliable and accurate. I was on the fence about it because of the price but I'll tell you what, I won't be buying an upper from any other company. RTB veteran to veteran thanks for having such a phenomenal company

    Top of the line product

    I'm very happy with this product. when I receive it in the mail (very fast delivery) and opened the package, I thought I received the wrong product. After looking back at my order and the spec on this product, it was correct. I have placed a few other orders from Right to bear and will continue to purchase from them. There customer service is the best. You get a live person that answers the phone.

    10 1/2" .300 blackout with a 9" M-Lok

    2nd review posted same upper. I was really impressed with RTB in how quickly this made things right. I have shot my 101/2" .300 blk upper now...it was along walk to the backyard...it looks good and functioned properly. It will probably be my car gun once I get another red dot for it. Thanks RTB great price ....it was to good to pass up...
