Daniel Defense M4 12.0 Front Sight Free Float Rail System Product Info
Daniel Defense M4 12.0 FSP Carbine Rail DD-1003 is a versatile method for mounting a slew of weapon accessories to your M4 or AR-15 carbine. At just over a foot in length, these Daniel Defense mounts are long enough to securely hold several different accessories, especially when you take into account the fact that there are military standard 1913 Picatinny rails on all four sides of the system. Daniel Defense has designed these rails with a small cutaway portion on the top rail that allows the front sight post of your weapon to protrude, giving you an analog aiming method when you don't want to use your laser sight or whatever else you have mounted on the rails. What's more, the cut only applies to the top rail, so you can use the other three rails of the Daniel Defense M4 Front Sight Carbine Rail System to their full capacity. Each rail on these mounts is protected by santoprene ladders or panels, and the whole package is machined out of aircraft-grade 6061-T6 aluminum. For a natural-feeling, durable, and versatile mechanism for mounting multiple weapon accessories to your carbine, choose the Daniel-Defense M4 Rail Handguard System 12.0.
