how do you attach a forward grip to a non-quad rail handgaurd? i've seen photos of ARs with picatinny rails attached to the bottom of a standard handgaurd, then whatever foregrip/light they have

There are companies that make rail sections to mount on standard handguards. You install one on the bottom handguard half, then mount the VFG to that.

GG&G makes one:

You probably don't need the entire handguard but for reference:

i've heard from other people that if you screw the rail on too tightly, you might crack/stress the handguard.

should i worry about that (or get a smith to install?), or get something like this: http://rmgrip.com/

Hmmm. Sounds like cheap handguards to me.

think that CMMG M4 handgaurds with a double heat shield would be strong enough? :cool:

Probably. You'll need to remove internal heat shields to install the rail though. Not sure if there's enough clearance to put the heat shields back in.

If they're designed like the real Colt M4 double heat shield hand guards, the heat shields are retained by tabs that fit into corresponding slots in the hand guards.

If you look around you can find rails for a lot less money. Given that it's attached to a plastic handguard, I wouldn't sweat it being particularly strong. The weak point will be the handguard attachments.

GG&G makes great stuff, but you pay for it. For your purposes, I doubt it's necesary. If you look around, you can probably do even better than this:

My scrap parts carbine uses an MI rail section on the lower handguard for the light...

how did you attach it, and does the handgaurd have a heatshield?

My .02 cents that if you use the mounts on the plastic handguards for anything other than a light or a small bipod..................they break, doesn't matter who makes them, verticle grips on plastic hanguard it's only a matter of time........:chris:

I wish I had enough "scrap" parts to put together another rifle:)

It comes with special nuts that fit inside the handguard.
The handguards have heatshields and it was not necessary to remove them.
This is by-no-means a solid setup.

As the Pirate says, it's barely good enough for a light.
It moves around quite a bit with the vertical foregrip.
I recently got a "scrap" rail system that will be going on the scrap parts gun soon.

In my defense, it was just the upper that's scrap parts. :D

could it be possible to screw it down anymore to prevent movement? if i have a VFG mounted, i would want it to be soild.

The rail does not move in relation to the handguard.
The whole lower handguard moves on the barrel.
If your intention is to put a vertical foregrip on, then you don't want one of these type of rails.
You need to get a proper freefloat railed handguard that will be solid.

hm. well, i'll see what i want to do when i order my upper. theres a chance i might not even want a VFG, and if i do, i might just buy rails to replace the handgaurd.

The "snap in" type of rails are not nearly as solid as dedicated rail systems.
If you try them and they wobble, don't say I didn't warn you. ;)
I set you up with a Stag or LMT upper with a rail system already installed.

Well, I was planning to go with a CMMG 14.5" (with a perm attached hider) M4A1 SOCOM upper with double headshielded handgaurds, and see how i like it; it's my first AR. later on if i want a rail system, i'll probably get a set of YHM's
