The Leapers UTG PRO Monolithic M-LOK Handguard is a precision 13.65 optics and handguard solution for the MP5 platform. CNC-machined from 6061-T6 aircraft-grade aluminum, it features a patented Claw Mount locking interface for a secure, repeatable zero. This monolithic system provides an extended 16-slot Picatinny top rail and 17 full and 5 half M-LOK slots for modular accessories. Designed with dehorned corners and melted contours to prevent snagging the charging handle, it includes a specialized cutout for easy viewing of the firearm serial number. Note: This monolithic design creates a single, rigid 13.65-inch platform that bridges the handguard and receiver to provide maximum rail space for modern optics and lasers.
