Designed and manufactured by Lewis Machine & Tool Company, the patent-pending Monolithic Rail Platform, or MRP, is the most radical variation of an integrated rail system ever conceived. This one-piece receiver/free- floating* handguard/rail system is precision machined from a solid aluminum forging for absolute strength and consistency.  The MRP completely replaces the upper receiver and provides an unprecedented level of  versatility to the operator. The "MRP" version of the upper is a "rifle" length version with longer quadrail. It accepts longer barrel lengths from 14.5 up. The "MRP CQB" upper is a carbine length version that will accept shorter barrels from 10.5 up.  The "CQB" carbine length version is pictured.  Please specify on your quote request if you want the longer "rifle" length MRP upper as there is a price difference.  Optics, accessories, and foregrip are not included that are pictured but are available for additional cost.
