Radian Weapons Model 1 Builder Kit 10" M-LOK Handguard Billet Upper Receiver - FDE

The Radian Weapons Model 1 Builder Kit is an AR-15 upper assembly package that pairs a billet upper receiver with a 10" Magpul M-LOK handguard, all finished in Flat Dark Earth.

At the heart of the kit is a Radian billet upper receiver featuring an integrated Picatinny rail, a dust cover with anti-rotation pin, and a lightweight forward assist pre-installed at the factory. The matching 10" M-LOK handguard is manufactured by Magpul and provides a slim, lightweight platform for mounting accessories via the M-LOK modular attachment interface.

The Model 1 Builder Kit also includes the small parts needed to complete the upper assembly: a 1x Enhanced Takedown Pin Set, an aluminum barrel nut, and 4x handguard cross bolts with matching washers and nuts. An ambidextrous magazine release is included to complement Radian's ambidextrous control design.

Finished in Flat Dark Earth throughout, this builder kit provides the foundation for a quality AR-15 build. Note: This is an upper receiver kit only and does not include a barrel, bolt carrier group, lower receiver, or other small parts required to complete a functional firearm.
