Description
PWS MK218 Mod 1 .308 Rifle — A piston-driven AR-10 that balances precision and reliability. We’ve handled this rifle in our Rapid City warehouse since summer 2025, and it consistently impresses with its durable construction and tight machining tolerances. At 7.9 lbs on our bench scale, it’s lighter than most .308 platforms without sacrificing durability.

Stand-Out Features
The MK218 Mod 1 stands out with its long-stroke piston system — we’ve found it runs cleaner than direct impingement AR-10s, especially during extended range sessions. Our customers report excellent reliability with both brass and steel-case .308, with a 4.6/5 satisfaction rating across 14 verified buyers.
