YHM® is very pleased to offer our flagship BLACK DIAMOND® Specter XL Top End. The Black Diamond® forearm bridges the gap between the upper receiver and handguard and is marked for position on all 4 sides.

    I've run this upper on my AR for 7 years without a single failure. Look and build quality are top notch. My build consists of YHM upper and lower except for a custom trigger group and the rifle is consistently accurate within 1 MOA. I couldn't be happier with my decision to go with YHM and buy this upper.
