AIM MT057 Extended Length Carbine Rail System


The MT057 from AIM Sports is the latest version of their incredibly popular, incredibly priced AR15/M4 quad rail. This version fits around the front sight post - with no gunsmithing required - to provide more real estate on carbine-length guns! Fits carbines with the standard CARBINE length gas system and handguards (replaces carbine length handguards which are slightly less than 7" long).

  • Precision Machined with Maximum Strength
  • Four Mil-spec Picatinny Rails with Free Float Extension for Versatile Accessory Applications
  • Simple and Friendly Installation, no Gunsmith or Tool Required
  • Solid Locking Features for Most Secure Fit
  • Ultimate Tactical Solution to Enhance Accuracy under Toughest Environments
  • Fits Carbine Length AR-15s
  • Hard Anodized Finish for Wear Resistance
  • Rubber Rail Guards Included for Great Comfort and Protection


  • Please note this is NOT a free floating rail system. Only the forward extension portion of the rail system (from the gas block on) is "free floating". This is a very rigid system but not a true free float tube. It is designed for installation on standard carbines without the need for removal of the delta ring, handguard cap (required for installation), etc. If your gun is in a configuration which does not allow for installation of standard plastic carbine handguards, this product will not fit properly!
