Anyone have installation instructions? It is the BT 21343.
I taped the the rail system to the shroud with masking tape and marked the location for the holes. I drilled and tapped the holes in the shroud itself for the screws. I ground the screws down to the proper length so they would not interfere with the can. I did not use any type of insert. As SDduc996 said, there was enough thickness in the RDTS shroud to hold the screws (barely). I don't know about the S&H Shroud.My cleaning slots are also offset on my S&H conversion. Did you tap the shroud or drill a hole in it and put some kind of insert behind it? It certainly explains why it wasn't fitting up right.
You can always attach a small piece of rail to the shroud, and cut the standard handguard around it.Same here on the shroud thicknesses. I don't think it is possible to mod the slots on the bottom to make it work without destroying the integrity of the shroud. I'll work with a local smith to see if he can drill and tap holes in the shroud like yall have done. I need the rail to get a light and IR laser on it. The only other way I've seen is to hang them off of the can, and I'd rather not do that.
