A while ago I found a site with a guy offering to add a rail to an HK-91 wide handguard for mounting a vertical foregrip. For some reason I didn't post it here. The real interesting thing, though, was the technique of using a sling with the foregrip to minimize the effect of recoil. Apparently, with an appropriate sling tension, by pushing forward on the foregrip, one can better keep the rifle in line with the target. It certainly made me revisit my stance on foregrips.
