Just my .02 but I think the US Palm grip is fantastic and have used them on 3 AK's. Not a required upgrade for a fighting carbine but a nice one.

On another note... I need to pick up one of the snap hooks of the sort that come on standard slings. My SGL-21 didn't come with any type of sling. I am currently running a BFG Victory series 2pt sling utilizing a UWL for the front sling attachement point, and while functional I find it not my personal preference. Does anyone know of a source for a compatible snap hook or is it best to just buy a carry strap sling to cut up?
