Hi,
In lieu of buying a full-railed front handguard for the GSG-5, has anyone added a bottom rail directly to the existing handguard?
There was a video on YouTube that had one on it, it looks like they shimmed underneath the rail at the front to keep the rail parallel to the barrel, and not sloping up with the handguard.
I'd like to simply add a front vertical handle.
I'm also thinking it would be easier to do it to the "slim HK" handguard I've seen on some of these rifles...

Thanks in advance,
Keith
