Product Features & Specifications
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.
Brownells BRN-10 Retro Slip Ring replicates the contour of the slip rings used on early M16 rifles, so it’ll add an extra touch of period authenticity to your next "retro" AR-style .308 build.
Just combine the BRN-10 slip ring with a .308 barrel nut, handguard spring, and snap ring to add the correct handguard retention hardware to your barrel.
The “flat” exterior of the Brownells BRN-10 Retro Slip Ring enables the use of non-free-float drop-in handguards on your .308 AR.
Aluminum construction Flat exterior, no taper like modern delta rings Fits DPMS and Armalite pattern rifles.
The BRN-10 Handguard Heat Shield Liner is a factory replacement part and is sold as a single unit. If you need to replace both of your BRN-10s.
