I picked up this AR last week. I'm in Massachusetts so I saw a pre 94 at a reasonable price and jumped on it. Anyway it seem to be in good shape but I would like to swap the handguard out to something with m lock and picatinny. The handguard on it is a free float carbon fiber with no way to mount iron sites or anything for that matter. Not sure how to remove this. I read online sometimes they are epoxied on. Anyone have any first hand experience swapping these out?
