The Phase 5 Weapon Systems M-LOK rail section is a compact 1.55" accessory mounting solution designed for modern tactical rifles and carbines. If you're running an M-LOK handguard or rail system and need to add or extend your mounting real estate for optics, lights, foregrips, or other gear, this black anodized rail segment gives you a rugged, standardized platform without the weight or bulk of a full-length system. It's the kind of no-nonsense addition that works just as hard as you do.
Built by Phase 5 Weapon Systems—a name trusted in the custom AR and modern sporting rifle community—this rail section is anodized for corrosion resistance and durability in the field. The M-LOK mounting pattern is now the standard on most contemporary handguards, making this a versatile upgrade for shooters who want precision rifle setup options without compromise.
Whether you're building a lightweight carbine, setting up a precision rifle for the range, or configuring a duty-grade setup, this rail section integrates cleanly into your existing platform. It's a straightforward, hardworking piece of kit—exactly what you need when you need it.
