Posted 15 Nov 2016 (edited) I need a SWR Hems 2 piston for a HK Mark 23 (M16 RH). New or used is fine. Maybe youve got an extra from a demo in a drawer? Stalking Rhino doesnt have any. Neither does Silencerco. Thanks in advance. BachelorJack@gmail.com Edited 15 Nov 2016 by BachelorJack Fairfax, Virginia, United States Share this post Link to post Share on other sites
