Daniel Defense Mk18 RIII 10.3" Upper Receiver Factory - FDE

This is a new Daniel Defense upper, but removed from a new rifle:  "take-off" model

After years of making a commercial variant of the Mk18, DD has evolved to the RIS-III in M-LOK, and it is a really cool rifle and a great upper receiver group.  And, yup, DD still has a 10.3" CHF barrel.  Daniel Defense's 10.3" barrel is a classic, and one that is asked for by customer over and over again.  There are three very good barrel makers for short barreled rifles with a chrome lining:  Colt, FN, and DD.  You will not be disappointed.  In fact, you might just fall in love with the updated M-LOK and the familiar RIS bolt-on connection.  It is slick.

The heritage of the DD RIS rail goes back to 2005, when SOCOM saw the need to get the handguards and all the accessories that had been piled onto the quad RAS rails off the barrel for better accuracy.  The M4A1 Block 2 rifle with the Daniel Defense RIS-II rail become the first general use rifle with a free float handguard and a large platform for lights and lasers and whatever else could be thrown on a Picatinny rail.  The Block 2 CQBR was then adopted by the Navy and Marines as the Mk18 Mod 1.  And, Lord knows, that the team at Charlie's makes a number of Block 2 uppers as well as the CQBR version and the Mk18 Mod 1, all based upon DD RIS-II rails.

The RIS-III or RIII brings you a blend of the traditional Mk18 with the convenience of the M-LOK and slimline RIII rail.
