The Daniel Defense 12.0 FSP Free Float Rail System features an opening in the top rail to accommodate the front sight post and gas block of a carbine length AR15 gas system. This precision cut-out provides much needed rail space along the top, sides, and bottom rails of the 12.0 FSP. The rifle’s front sight post protrudes through this opening but does not diminish the usable mounting area on the rail that extends beyond the gas block and over the carbine’s barrel.

This extra “real-estate” is a perfect location for aiming devices, flashlights, and laser sights.

The 12.0 FSP handguard was designed to work with the AR15 carbine gas system. The indexing pins are stainless steel while all other components are 6061-T6 aluminum. The finish is Mil-Spec hard coat anodized black. Rails are 1913 Mil-Spec and are 100% checked for conformity.

Every rail comes with black ladder panels which are made from santoprene, which can handle heat up to 350.

Construction

The Daniel Defense M4Rail Handguard System was designed around these parameters:

• Must be free float.
• Must be light weight and strong.
• Must be able to quickly dissipate heat.
• Must feel like a conventional rifle forearm (Oval not round).
• Must lock to barrel nut or upper receiver to prevent “handguard spin”.

Material & Construction

Precision CNC machined from a block of 6061 T6 aluminum and finished in hard coat type 3 mil-spec anodized black for a rock hard lasting finish while weighing in at a mere 12.5 ozs.
