Drilling a hole in carbon fiber handguard

[usmc1371]

I did drill a hole in my cf handguard. You are going to need a backer ring. Most likely the cf is about .08 thick. Any bolt or stud will have about 1 thread. I made my ring out of 4140 steel. One piece. I glued it in place the used two sling swivel studs and one 10-32 screw. It holds up real well.
