B&T Firearms
The B&T Handguard 3X Nar for MP5K delivers a modular rail platform purpose-built for the HK MP5K platform. This three-sided Picatinny handguard replaces the factory handguard with an accessory-ready design that lets you mount optics, lights, and other tactical gear exactly where you need them. If you run an MP5K for home defense, training, or tactical work, a railed handguard transforms your capability without requiring a complete upper receiver swap.
The 3X Nar design provides three full Picatinny rails—top, left, and right sides—giving you flexible mounting options while keeping the handguard lightweight and maneuverable in confined spaces. The all-black finish matches standard MP5K aesthetics and blends with tactical setups. Installation is straightforward for anyone familiar with MP5K takedown, and the fit is specific to the MP5K's narrow profile, so you get a solid, rattle-free platform that doesn't compromise the gun's handling.
Whether you're building a precision .22 conversion trainer, a dedicated low-light work gun, or just want more accessory real estate on a short-barreled platform, this handguard opens up options without reinventing your base rifle. B&T USA engineering means solid tolerances and finish quality you can trust in a duty or frequent-use setup.

The B&T 3X Nar is designed for the MP5K platform. Fitment on clone or variant receivers depends on whether they maintain standard MP5K profile and attachment points—when in doubt, confirm with B&T or your gunsmith before purchase.
The handguard features three-sided Picatinny rails, so any standard Picatinny-mounted optic, light, or accessory will work. This gives you broad compatibility with common tactical add-ons.
MP5K handguard swap is a field-strippable task if you're comfortable with basic takedown. We recommend consulting an armorer or detailed install guide if you're unfamiliar with MP5K assembly, but it's not a complex build.
