5 o' clock light mount?

[solizone]

Is there any tactical light mount that is mounted onto the lower part of the front sight or the gas block (I only have standard handguards) at the 5 o' clock position? it looks easier for my offhand to use the light. I'm looking for the same or close to the same light mount used in the AR's in the Blood Diamond movie.

Any suggestions or recommendations are greatly appreciated!

There are strap-around and hard-mount-around the regular handguards that exist, and would work easier, especially with a 20" rifle.

I considered hard mounts but most of them requires modifications to the handguards and removal of the heat shield so I would not prefer that option. But I found this mount at Brightflashlight dealer sells which looks like the one's i'm looking for. The middle one I circled, is a barrel mount that includes a light holding ring at the 1-11 o' clock position. It looks like if it's turned 90 degrees or so fourth, it could mount onto the front sight housing and still has the light at the 5 o' clock position (1 o' clock is parallel to 5 o' clock). Does anybody think this would work?

No, there are several light mounts going around A2 handguards requiring no modification. One's a strap (not bad) the other is a hard plastic mount that basically adds a piece of M1913 rail in place on the ring of plastic going around the actual handguard (seen pics, don't know the name).

There are also replacement stock handguards which have sections of rail already mounted from Brownells I believe.
