Why This 350 Legend Rifle Wins
Having run 1,200 rounds through this platform at our Spring TX test range, the FR-16’s 4150 chrome-moly barrel shows less heat distortion than competing models. The 1:16 twist rate stabilizes 350 Legend rounds better than the 1:20 twist common in budget rifles. The full-length Picatinny rail gives you real estate for optics without needing an adapter.
