Our 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 Barrel nut, handguard spring & snap ring Mfg: Brownells
