819064010340 The KAC M4 RAS (Rail Adapter System) was developed for use on the US military's M4 Carbine, and with over 1 million rails issued to date, it is one of the most battle proven designs available for the AR-15 platform. This non-free float handguard is a simple-to-install, drop-in upgrade that features genuine Mil-Spec M1913 Picatinny Rails along its entire length. What sets the M4 RAS apart from other 2-piece quad rails on the market is that it securely locks to the rifle's barrel nut via a clamp and screw arrangement, making it a very solid foundation upon which to mount tactical accessories. Includes three KAC 11 Rib Rail Panels. Rifle Requirements: The M4 RAS is a drop-in replacement part for standard, 2-piece polymer, M4-type handguards. The rifle must have a carbine length gas system, delta ring assembly, fixed front sight/gas block, and round handguard end cap. Lighter barrel profiles work best (M4 or Government contours). Heavier barrel contours may require modification to the inside of the rail. For AR-15/SR-15 based platforms only; not compatible with SR-25 variants. Installation instructions are included.

Brownells USA One of the best carbine length rails 07/06/2018

One of the best carbine length drop in handguards on the market. It's not cheap, but you get what you pay for. Installation is a breeze, and once installed it locks up nice and tight. It comes with integrated heat shields, which come in handy during extended firing sessions. Most other handguards do not have heat shields, and warm up really fast, and can become uncomfortable. (Trust me, I've tried the DD Omega 7.0, it does nothing to protect you from the heat generated by firing your rifle.) The 1913 rails are machined well, and accept just about every accessory on the market. Perfect handguard for those building an M4A1 block 1 or block 1.5 clone, but works well for all purposes. My duty weapon was equipped with this handguard, and now my civilian weapon is too.
