Magpul | M-LOK Polymer Rail | Black

Magpul's M‑LOK polymer rail sections give you a genuine 1913 Picatinny mounting point anywhere you need one on an M‑LOK handguard, at a fraction of the cost of running aluminum rail everywhere. Glass‑reinforced polymer construction resists corrosion in wet or sandy conditions, beveled ends eliminate snag points, and integral recoil lugs keep the section locked in place under recoil instead of walking loose. Available from 3 to 11 slots, so you add exactly the rail you need and nothing more.
