Description

The Colt 7" Drop-In AR15/M4 Carbine Length Quad Rail was developed for use on M4 Carbines with a 14.5" or 16" barrel. One of the most battle proven designs available for the AR15 platform this handguard is a simple-to-install, drop-in upgrade that features genuine Mil-Spec M1913 Picatinny Rails along its entire length. A rock solid platform to mount tactical accessories.

A true drop-in replacement for standard 2-piece plastic M4 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 profile). Heavier barrels may require modification to the inside of the rail. For AR15/M4 based platforms only.

  • Installs in minutes

  • Compatible with carbine length gas systems

  • Weight: 8.9 oz

    Wanted my colt M4 to look like my Iraq service weapon and this did the trick. Well made and easy to install. Thanks for a great product.

    Colt 7" Drop-In

    Not just any "drop-in" quad rail. This Colt quad rail is a high quality railed handguard that is screwed together and provides a secure mouthing platform for accessories. Once installed it doesn't shift or rattle. Ad best of all it's genuine Colt.

    Excellent Fitment and High Quality

    I have both KAC and Colt carbine length drop in 4 rail. For the Purist, the Colt is the way to go with all Colt M4’s and Colt variants.

    It’s a colt product

    A little expensive for a non free float rail, but less than a KAC. Secure fit, good finish and machining. Colt logo on top.
