Key Features
- Adjustable Magpul PRS Stock: Comb height and length of pull adjust without tools, so you can dial in a perfect cheek weld and eye relief for any shooting position. Why it matters: consistent head placement means consistent shot placement.
- 20-Inch Midlength Contour Barrel with Triumvir Muzzle Device: The barrel balances weight and rigidity, while the Triumvir brake reduces recoil and flash. Why it matters: faster follow-up shots and less muzzle rise during strings of fire.
- Forged 7075-T6 Aluminum Receiver: Mil-spec strength with a corrosion-resistant hardcoat anodized finish. Why it matters: this receiver handles the pressure of .308 Win round after round without warping or cracking.
- 14-Inch M-LOK Handguard: Full-length top rail and M-LOK slots at 3, 6, and 9 o’clock let you mount lights, lasers, bipods, and grips exactly where you need them. Why it matters: no adapter plates or drilling required—just attach and go.
- Ergo Ambidextrous Sure Grip & Magpul MBUS Sights: The grip fits both left- and right-handed shooters, and the flip-up sights are ready out of the box. Why it matters: you can start shooting immediately without buying extra accessories.
Who It’s For
