M4 fore grip mounting
 

Would somebody kindly point me in the direction of a supplier of the circled style of fore grip. It seems to mount without needing rails to a standard M4 front end.

There is a small rail mounted to that forestock !

I'm getting in a few rails that mount to a standard handguard like that, that allow you to use railed accessories. ETA is about 1-2 weeks.
