foregrip as in the front rail system? the rails should be almost even across the entire top of the rifle. and the sights should be mounted right to that. not on any riser's or grips. perhaps im miss interpretating what your trying to say. a picture would be helpful.
I have been a silent witness
to all of America's finest hours.
But my finest hour comes
when I am torn into strips and used as bandages
for my wounded comrades on the battlefield,
When I fly at half-mast to honor my soldiers,
Or when I lie in the trembling arms
of a grieving mother
at the graveside of her fallen son.
