MK18 RIII 10.3" STRIPPED UPPER RECEIVERS W/ LAW FOLDER

Brownells has paired the Daniel Defense Stripped M4A1 Upper Receiver with the ever popular LAW Tactical Folding Stock Adapter! The Daniel Defense upper is finished in the Desert Dark Color they are known for and we have added the option of either a black or flat dark earth folding stock adapter. Adding to their extremely successful line of stripped MK18 Daniel Defense uppers, Daniel Defense now has the stripped MK18 upper with their RIII rail! The MK18 RIII™ AR15 style Upper Receiver Group is unmatched in size, weight, and performance, and is built around a 10.3 inch Cold Hammer Forged M4 Profile barrel and a carbine length gas system. It features a 9.5 inch lightweight RIS III rail—modeled after the revolutionary RIS II two-piece handguard developed for SOCOM— which features M-LOK attachment for lighter weight.
