Part Number DD-1006
The Daniel Defense 12.0 Free Float Rail System was the first handguard designed and bulit by Daniel Defense and it is a tremendous upgrade for users who require a light and rugged rifle with long range capability. This rail is machined from the highest quality aircraft grade hardened aluminum yet it only weighs 13 ounces (including the threaded ring, barrel nut, and indexing pins)! The high strength and low weight of this remarkable handguard contributed greatly to its adoption by the United States Army for the Squad Designated Marksman Rifle program.
 
The Daniel Defense 12.0 rail system helped deploying Army units issue a squad level precision rilfe that bridges the gap between infantry rifleman and a battalion level sniper asset. The 12.0 handguard was designed to work with the AR15 riflelength gas system. It will also work with the carbine or the midlength gas system with a milled gas block that will fit under the handguard.
 
Rails are 1913 Mil-Spec and are 100% checked for conformity. Every rail comes with either ladders or panels which are made from santoprene, which can handle heat up to 350 degrees.
