5 of 5 Great quality and great price. August 22, 2020
Reviewer: Jeremy Parent from Troy, MI United States  
This is the perfect addition to my rifle build. The nickel boron coated bcg was the perfect touch. I will be returning in the future for my pistol build.

5 of 5 Outstanding quality and service August 10, 2020
Reviewer: Hilliard Trahan from New Iberia, LA United States  
I ordered a 300 blackout upper and it arrived quickly. I was a little skeptical on what I would get . It arrived within a week considering it was a late night order. I received an email from an actual person when it was shipped . Nice touch!  I had bought a lower from another company still mil spec. The upper fit perfectly with no play. I was  so impressed I purchased a 223 wylde upper from them after I received the first order. Again it was shipped quickly but it had a 3 day delay from the post office itself. Not the vendors fault covid issues with shipping. I am on my phone so pardon any spelling  errors. Great job and I will purchase from them again.Honest 5 stars here no bs.
