Blackhawk wisely labels both the top and bottom halves, but also each mounting groove. While technically it does not matter which of the halves of the Blackhawk! Quad Rail go on the top and bottom, they are labeled accodingly. Not only will you bend the gas tube, you’ll burn the bejeepers out of your hand when the barrel heats up. As tempting as it might be to use it like this, don’t. Piece of cake right? Now you’ve got an AR-15 that looks something like Skeletor. When you pull the delta ring towards the receiver far enough, you’ll be able to remove each half of the existing hand guard as shown in the photo here. It may be tight, so apply a little muscle. Just pull down on the delta ring between the receiver and the forend. While the existing forend may appear to be a “tools required” removal, it’s not. The first step is to remove the existing hand guard.

The Blackhawk! Quad Rail Forend includes two aluminum rail halves that dovetail together, 4 hex screws for fastening them to each other securely, a hex wrench and a single page of installation instructions.

Let’s take a closer look at the installation process: No need to remove the sight block or hand guard cap – just install each half and bolt them together. The whole idea of the two piece quad rail is that it’s a drop in replacement for the standard two piece hand guards. Well, there is one small allen wrench, but that’s included in the box. Unless you stray really far from the simple instructions.

The best part about this accessory? No tools required! Not even a hammer. As you’ll see by the close-up photos below, the airflow is great and unrestricted. The Blackhawk! AR-15 Quad Rail Forend is made of aluminum and features at least 3.17 boat loads of vent holes to help dissipate heat during prolonged or rapid fire.
