The M400 TREAD V2’s cold hammer-forged barrel provides exceptional accuracy and longevity by work-hardening the steel during forging. The 1:8 twist rate stabilizes a wide range of bullet weights from 55 to 77 grains, making it effective for both lightweight varmint rounds and heavier match-grade ammunition. The free-float handguard prevents point-of-impact shift from sling pressure or bipod use.
