Aero Precision Monolithic C.O.P.(Continuous Optics Platform) AR15 Upper Receiver Kit- Carbine Length

This exceptional monolithic upper receiver and handguard is a customizable kit that will take any AR carbine to a whole new level. This is an extremely rigid, user configurable, free-float handguard rail system. This system's upper rail as part of the upper receiver ensures a single, rigid, in-line platform for optics and irons.

 This system uses any standard AR-15 barrel, not a proprietary barrel system. BARREL NUT and WRENCH are included with the kit. The receiver design also has a fully enclosed dust cover pin which can be removed with the barrel in place. Forward assist and dust cover already installed. ALL necessary tools are included to finish every piece of this kit's rail system (20 screws included, only 18 needed to build).
