Radian is known for making some of the best AR parts and accessories in the market, and if you are looking to build a new AR-15 rifle, you should check out the Radian Model 1 receiver and handguard combo set. This set comes with a 14-inch handguard, ideal for a rifle with a 14.5-inch barrel or longer.

Structurally Reinforced

The Radian Model 1 receiver is made from 7075-T6 aluminum, and to ensure longevity and strength, it is also reinforced at certain high-stress parts like the chamber. Like most AR-15 receivers, this receiver features a port door and a forward assist. However, the forward assist has a lightweight minimalist design for better ergonomics. You also get a Raptor-SD Ambidextrous Charging Handle with the set.

Perfect For Carbine or Rifle Builds

The handguard is 14 inches long and is also made from aluminum. This low-profile handguard features M-LOK attachment points on both sides, and the bottom, with a full-length top Picatinny rail. The handguard comes with an anti-rotation pin, which ensures that any optics or accessories mounted on the handguard retain zero. Moreover, this handguard is designed to be comfortable to handle, and all of its cuts and edges are therefore chamfered.

This upper receiver and handguard set are available in multiple finishes, including Cerakoted Black, Flat Dark Earth, or OD Green.
