The UTG Pro SD Monolithic M-LOK Forearm Add-on extends the front of your MP5K handguard with a 4.2" cylindrical forearm that gives you a better handhold and more M-LOK mounting space. It is compatible with most K-length suppressors and up, and the two-inch inner diameter leaves M-LOK hardware room to clear bare or wrapped suppressors while improving heat dissipation. This is an add-on rather than a standalone handguard: it requires the UTG Pro Monolithic M-LOK handguard made for the MP5K and similar clones, so plan to pair the two.

The forearm is machined from 6061-T6 aluminum and finished in Type III Class 2 matte black anodizing. Steel hardware is included, so the fasteners for mounting it come in the box. The cylindrical forearm adds additional M-LOK real estate, giving you more places to attach M-LOK accessories along the front of the gun. Leapers designs and makes it in the USA.
