BS Systems B5 Car15 Handguard Blk
The B5 Systems CAR15 handguard brings practical retro aesthetics to modern AR-pattern rifles without the weight penalty. If you're building a lightweight carbine or prefer the clean lines of classic mil-spec furniture, this slim-profile handguard delivers that signature look in a drop-in package. Built from durable composite materials to mil-spec standards and manufactured in the USA, it's a no-fuss upgrade for shooters who want function over flash.
The CAR15's appeal lies in its honesty: a lightweight design that doesn't pretend to be something it isn't. The integral heat shield protects your support hand from barrel heat during extended shooting sessions, and the original 6-hole pattern lets you attach sling mounts, rail segments, or other accessories as your setup demands. At just 4.4 ounces, it won't slow you down whether you're running a hunting rifle, a plinker, or a general-purpose carbine.
Drop-in installation means you don't need a gunsmith or special tools—this handguard was built to work on standard AR-15 receivers. The slim profile keeps your rifle nimble in tight spaces, and the composite construction resists abrasion and weathering without the maintenance demands of raw aluminum.
