New "mismarked seconds" CAA X6 Carbine 6-rail handguard system. Has two rails on both sides of A2 style FSB for mounting lights and accessories. "Mismarked" because the T-markings for top and bottom rails are mismarked (top rail says B-xx, and bottom rail says T-xx). Cosmetic flaw doesn't affect function. $80 shipped.
