Pain in the butt to put on but worth it - ProMag Archangel Yugo Pap AK-Series OPFOR Forend Set

Like every other review has said, you have to sand the upper handguard to make it sit flush and lock in. If you don't have a belt sander, just sand slowly. The lower handguard fits pretty easily and follows the ancient YouTube video. The material feels firm enough, but won't protect you from the heat. There is a small piece of a heat shield on the lower handguard, but only the lower.
