100% Colt May 31, 2018
Reviewer: Daniel Gutridge from Round Rock, TX United States  
This upper is a 6921...just don't go by the thumbnail, You will recieve it with a Magpul MBUS and the front sling mount will be on the bottom of the FSB...not offset to the left. aside from those minor details, everything is Colt marked and high quality

Great upper! March 16, 2018
Reviewer: Daniel Baca from New Rochelle, NY United States  
Very happy with it but be careful because whats pictured isn’t exactly what you get. The rear flip up sight is a Magpul.

The (almost) GI M4 upper March 14, 2018
Reviewer: Bob from SEUS  
really, all it lacks is a Matech rear sight, M203 front handguard ferrule cuts, and side sling swivel to be perfect. It comes now (apparently, and from everybody) with the MBuis and swivel installed to standard front mount and guard ferrule. Upper is now cage code marked rather than C marked, both receiver and barrel, M4 stamped at rail front.
Front sight is F-height, although not marked, the guess being since all guns are flattop today, no need for marking.

For those wanting to know lengths, the upper with supplied A2 flash hider is 15 7/8ths", which is SBR. The length with a Smith Ent. Vortex is 16 1/4", a gain of 3/8ths". This is still 1 1/4" shorter than the 16.1" with A2 length of 17 1/2" total length. That 1 1/4" DOES make a difference in handiness in tight quarters, even that 3/8ths" between the A2 and Vortex is palpable. I will leave it up to you to decide whether the SBR route is worth it.

Free shipping? May 30, 2017
Reviewer: Max Staats from Choctaw, OK United States  
Package arrived with 95 cents "postage due".  Not a big deal, just annoying.
