Why You And Your Weapon Need This AR9 Upper With LRBHO

This upper receiver is the top of the line. It is made with lightweight but rugged aluminum and finished with an anodized hard coat. This means it can take the pounding of steady fire while maintaining good looks and high performance. It screams quality from every angle, and you know that your weapon deserves quality.

Your Shooting Experience Will Change For The Better

That is right, this upper is going to change the way you experience shooting. Like a courteous friend, this upper holds open the door for you when you need a reload. The last round bolt hold-open function keeps the bolt to the rear, telling you when the magazine is empty. It also results in a faster reload, since chambering the first round of the next magazine is as simple as slapping the bolt release.
