Geissele Super Duty Upper Receiver Group 11.5" DDC 5.56mm, stripped

with the wonderfully mated new unified Mk16 rail and upper receiver

Geissele Super Duty DDC upper receiver

The 11.5” complete upper in 5.56mm features a DDC upper receiver mated to a unique Mk16 MLOK rail with 11.5”  Phosphated, Cold Hammer Forged Geissele, Chrome Lined 1-7 twist barrel, stripped with no BCG, no flash hider and no charging handle

This is Geissele factory new, in Geissele box, ready for you to create your own AR pistol or short barreled rifle.

Geissele barrels are a new line for Geissele in 2020.  The barrels are precision machined and cold hammer forged. The carbine length gas system is perfect for the 11.5" barrel, and includes a Geissele gas Block installed at the factory with both lower set screws and a through the barrel pin.  This is something Geissele has been doing since 2018.  Is it necessary? No.  Extra protection from a gas block moving, which was never going to move in the first place, but something about the Geissele name has that German sound to it, that causes the entire firm to over-engineer, like Mercedes.

The newly designed 10.5” Super Modular Rail MK16 mates to the upper via a center aligning tab removing any chance of rail rotation. This rail is a variant of the 13.5” SMR MK16, currently fielded by USASOC, and one of Geissele's best sellers and best ideas.  At Charlie's, we like the way in which the upper mates to the rail, which also is a crutch to better align the rail and upper receiver.  That is a good thing.

The Mk16 rail is unique to this upper, as it has the dovetail fit to the upper.  This is not a standard Geissele Mk16 rail, nor is the upper a standard Geissele upper.  The two are meant to be used as one system.  The Mk16 rail has proved itself in battle as the US Army's USASOC new M4A1 upper receiver group, improved (URGI) found on the 14.5" Colt M4A1.  It has been very popular as it is stable, thinner and has MLOK on all eight sides.  The Mk16 rail has been probably the most popular rail for Geissele, since its introduciton in 2018.

Note:  Geissele has, over the years, used a number of forgings for their upper receivers, as well as a number of different flash hiders.  This particular forging in 2020 is either Brass Aluminum or Mueller forging.  No matter the forging, Geissele is testing each upper receiver for functionality and blemishes before putting a passing grade on the upper receiver.  Don't get hung up in the super details.  Trust the gun maker to make the right sourcing decisions.  We do.

The Super Duty Complete Upper from Geissele Automatics offers unmatched performance, accuracy and reliability.

Note:  DDC color can appear from tan to beige to green in pictures.  Actual colors do vary quite a bit, but for some reason, pictures accentuate the differences.
