Lancer Systems L5 Advanced Warfighter Magazine – .300 Blackout – 20 Rounds – Opaque Black

The Lancer Systems L5 Advanced Warfighter Magazine (L5AWM) (999-000-4280-05) is the definitive 2026-spec feeding solution purpose-built for the unique geometry of the .300 AAC Blackout cartridge. While standard 5.56mm magazines can technically chamber a few .300 BLK rounds, the thicker ogive of heavy subsonic bullets often causes binding, stack tilt, and catastrophic failure-to-feed malfunctions. This dedicated .300 BLK magazine (738435619503) completely solves this issue with an altered internal geometry, featuring a modified internal guide rib and a custom-contoured follower to ensure 100% reliable feeding of both light supersonic and heavy subsonic rounds.

The engineering core of the L5AWM relies on a revolutionary hybrid design: a high-impact, proprietary opaque black polymer body fused to a single-piece, wrap-around hardened steel feed lip assembly. This prevents the feed lips from spreading, cracking, or taking a permanent "set" under long-term spring pressure or extreme environmental shifts. The 20-round capacity configuration delivers a highly compact, low-profile footprint that is ideal for shooting from a bench, utilizing a bipod, or maneuvering inside tight vehicles and close-quarters environments. Complete with aggressive surface texturing and a non-tilt follower, the L5AWM is the gold standard for defense-ready .300 Blackout platforms.

Includes: (1) Lancer Systems L5AWM 20-Round .300 Blackout Magazine – Opaque Black.

Key Features

  • Dedicated .300 BLK Geometry: Engineered with a modified internal guide rib to effortlessly support heavy subsonic ammunition up to 220+ grains without binding.
  • Hybrid Steel/Polymer Design: Fuses an impact-resistant polymer body with hardened steel feed lips for permanent structural rigidity and flawless drop-free release.
  • Compact 20-Round Footprint: Provides a streamlined profile that drastically reduces snagging, simplifies vehicle storage, and clears obstacles when shooting prone.
  • Aggressive Texturing: Raised texture panels along the perimeter ensure positive, slip-free control during high-speed reloads, even when wet or gloved.
  • Heavy-Duty Stainless Steel Spring: Driven by a corrosion-resistant, non-fatiguing spring paired with a precision-molded anti-tilt follower.
  • Opaque Black Tactical Finish: Delivers a classic, professional aesthetic matching standard duty gear while keeping ammunition completely concealed from external view.
