5 of 5 First AR purchase July 28, 2023
Reviewer: Caleb Ellison from Houston, TX United States  
Great price and excellent performance!!! Put it through a stress test because this is America. Cycled 500+ rounds with ease and no jam sandwiches. I could not be happier for my first purchase! Will be buying another one very soon maybe even 308. Thank you Radical for a beast of a first rifle!!

5 of 5 First 300 blk out rifle February 14, 2022
Reviewer: Steven Cutler from South Carolina  
I wasn't planning to buy this rifle when I went into the gun store. I had planned to buy some mags for my AR. I spotted this on the rack and asked to see it. After looking at the price, I started looking for low end faults. After a few minutes of looking...I didn't find any! Very well made rifle. Fit and finish look as good as a rifle twice the price. My only complaint is that you make it in a 7.62, so now I have to have one of those too!! I'm glad to see it was made in the great state of Texas right here in the heart of the USA!! This rifle is worth it and then some.
