Sinclair Inc BRN-10® PROTOTYPE HANDGUARD RIFLE LENGTH | Sinclair Intl

A Retro Handguard for Your AR-10 Prototype

Many AR-15 enthusiasts don't know that Eugene Stoner's original AR prototype was actually an AR-10 rifle chambered for the .308 Win. cartridge! Only later did the 5.56 NATO rifle emerge as the primary design. The Brownells BRN-10 Prototype Handguard is a detailed reproduction of the original handguard found on these prototype .308 Win. rifle models.

The Brownells BRN-10 Prototype Handguard features the classic rounded shape of the 1950s-era handguards and feature six venting holes on each side of the handguard to promote barrel cooling.

  • Two-piece handguard design
  • Constructed from polymer
  • Measures 12 inches long
  • Available in black, brown or green

The Brownells BRN-10 Prototype Handguard is designed for use with rifle-length gas systems and requires a round front handguard cap for installation.
