Knight's Armament SR-25 Mk11 Mod 0 Free Float RAS Forend

The KAC SR-25 Free Float RAS (Rail Adapter System) was originally designed for the US military's Mk11 Mod 0 rifles. It features full length mil-spec M1913 Picatinny rails at the 12-, 3-, 6-, and 9 o'clock positions, making it compatible with any number of rail-mounted tactical accessories. The rail free floats the barrel, allowing for consistent barrel harmonics upon firing, and thus increased accuracy potential. Includes three KAC 11 Rib Rail Panels. 

Specifications:  

• Length: 12.25" 
• Weight: 17.2 oz 
• Free Float: Yes 
• Material: Aluminum

Rifle Requirements: It is recommended that this SR-25 Free Float RAS be used with a rifle length gas system only due to potential interference issues if a gas block were to be run underneath the rail. The top rail has a cut-out in it that is meant to be a recess for a folded KAC Mk11 Push Button Front Sight (PN: KM20138, sold separately). Disassembly of the rifle's gas system and removal of the factory barrel nut will be necessary. This forend uses a proprietary barrel nut that must be installed using a SR-25 RAS barrel nut wrench (PN: 10908, sold separately). Compatible with SR-25 or similar rifle variants only; not for use with AR-10's
