It’s perfect for adding all the goodies to the AR that you couldn’t add before. With the quad rail you can have a sight on top, a light on the side, a foregrip, etc. The quad rail became the staple in both military and law enforcement around the world. A 2 Piece Drop-In Quad Rail, as the name implies, comes in two pieces and screws together into place between the AR-15 receiver and front sight/gas block. The tapered end fits into the delta ring, which holds the quad rail in place against the end cap on the rear of the front sight This minimizes the variance in possible mechanical pressure distortions of the barrel alignment, and allows vibration to occur at the natural frequency consistently and uniformly, shot-by-shot.
The free-float handguard mounts directly onto the upper receiver and does not contact the barrel in any way. This enables the barrel to “float,” which increases firing accuracy. Using a free-float rail system / handguard can significantly increase accuracy when using grips and bipods Accuracy — As the handguard does not touch the barrel, there is less weight and pressure. Accuracy is improved. Comfort — A free float handguard offers more grip space, more room for comfortable accessories, and a long sight radius.
