Yugo SKS.. Why a NATO Spec Grenade Launcher?

It clamps to the sight leaf.

There appears to be a groove added to the RSB to allow for clearance for the mount to the leaf though... Look closely on that first pic with it installed on the leaf. Granted I don't have any /26\ SKSs between 65 and 78...but none of my RSBs look like that. It also seems like it might not work on a long lug barrel.  If my eyes aren't failing, that appears to be a short lug 67 it is installed on correct?

It also seems as if this thread has become derailed...for that I apologize.

Nope.. just clamps to the rear leaf.

I don't know Chinese geography that well. Is Shandong and Hong Kong one and the same? Or, in close proximity? The Ebay ad says the merchandise is coming from Shandong, China, while the Seller, (applebeez2014), is in Hong Kong. Just curious. Yeah, a bit off topic. But there's not much chatter on the board this past week. Gotta talk where you are, if that makes any sence since cents body wonder.  I think it's going to be a long winter. Especially if it's a BAD November. It may fry my last working brain cell.

I dunno...  Good question.   You try google maping the two?

Hong Kong is 1623 km SSW of Shandong.  Shandong is 364 km south of Beijing.
