The Leapers UTG Pro SD Monolithic M-LOK Forearm Add-on extends the handguard on your HK MP5 with a 4.2" cylindrical forearm sized for most K-length suppressors and up. The 2" inner diameter gives the M-LOK hardware room to clear most suppressors, whether they are bare or wrapped, and it also helps dissipate heat. It requires the UTG Pro Monolithic M-LOK handguard for the MP5 and similar clones, so you mount it on that handguard rather than on its own.

The forearm is made from 6061-T6 aluminum with a Type III Class 2 matte black anodized finish. The added length gives you an improved handhold and additional M-LOK real estate on the front of the gun. Steel hardware is included in the box, and the add-on is designed and made in the USA.
