I liked that rifle so much that I bought one in 300 Blackout this year. The gun has fired flawlessly, was a cinch to zero, and is significantly more accurate than the price would suggest. I buy American whenever possible, so I like that Radical Firearms builds their rifles in Texas. I'm sure that some of the high-end/designer AR15s are smoother or have a better finish, but the Radical AR shoots and functions as well as guns that cost twice as much. 10/9/2023 ** ** ** ** ** ** Gregory Indianapolis, IN From start to finish this process was pretty amazing. When the firearm arrived immediately put 200 rounds down range no issues.. I would highly recommend! 9/13/2023 ** ** ** ** ** ** Charles Pleasant Gap, PA I am impressed with this rifle.

Gun shot the first 150+ rounds without issue. 6/19/2023 ** ** ** ** ** ## Don't Forget Your Ammo ```json
