New to AR, no idea what this is (the thing on the barrel under the front sight):
Haven't seen this in any previous Norc AR threads, RO at my local range doesn't know what it is (he owns a 14.5 Norc, too), couldn't find it in AR part diagram. Any ideas?
BTW, have any other 10.5" CQ owners managed to install a quad rail WITHOUT modifying the gun itself (like replacing the handguard cap)? If so, could you share the model and the vendor you got it from?
