Xanthus Posted October 27, 2017 Report Share Posted October 27, 2017 (edited) Looking for a Sig factory polymer handguard for my 556xi. I know that some have replaced their polymer handguard with an aluminum one, so there must be some take-offs around somewhere. Any help appreciated. Thanks in advance.
