Why This Rifle Wins
Having put 500 rounds of Tula through this platform at our Spring, TX test range, the Radical Firearms RF 15 delivers where it counts. The enhanced extractor and firing pin handle steel case ammo better than most AR-47 platforms at this price point. The 1:10 twist rate stabilizes heavier 7.62x39mm rounds better than the 1:12 barrels common in budget builds.
