Norinco 982 GRS
I have the standard 98 model. When I saw the GRS on the 982 I recognized the sight as the WGRS-37 from Williams Gun Sights.
Found one on GunBroker for $27 shipped and all is good. I wasn't going to use a shroud like the 982, but I may need one with the front sight I am planning to use.
Has anyone identified the rear sight shroud or know of sources for other shrouds?
