$2,122.14
For more than 50 years, the famed silhouette of the M16/M4 has only had one major and several minor changes. Barrel lengths and buttstocks have changed, but more or less the evolution of America’s right arm has proceeded apace with each generation of warrior making her their own. In that time, the sight of the M16/M4 in the competent grasp of young Americans has meant hope to countless millions of people around the globe. With the advent of the Geissele USASOC AR15/M4/M16 Upper Receiver Complete Group, that quintessentially American silhouette has changed forever. The Geissele USASOC AR15/M4/M16 Upper Receiver Complete Group combines the handguard, hammer forged barrel, and mid-length gas system to work in concert for a package that delivers measurable increases in hit probability. Designed to take the full rigors of the new M855A1 (AB57) ammunition, these AR15 Upper Receivers also take full advantage of its capabilities. Once the Geissele USASOC AR15/M4/M16 Upper Receiver Complete Group is installed on an existing system, it essentially makes for a brand new weapon. It is a near-clone upper receiver group currently going into service with USASOC. NFA DISCLAIMER/WARNING: This item contains a permanently pinned and welded muzzle device.

I received this promptly from Optics Planet. I have not shot this yet so this is all subjective observation. It is a very solidly built, well finished upper. It was a little more 'golden' in hue than I had expected. Not a negative. Well packaged. It came with a three wire braided spring and an H1 buffer. The spring was what I would have used if none came with it. The upper was well-oiled with some light viscosity oil. The charging handle looks decent. Until I actually shoot it, not much else to say but if there are any faults when I do shoot it I will make another post. That said, 9-Hole Reviews really seemed to like it.

Best upper I’ve ever shot it does everything great only downside is it’s heavy

This upper is flat out the bees knees. I got one about a year and a half ago when they were still available… now all I see is “backordered” or “discontinued” as stock. All I know is if you can find this upper, buy it. It’s not real cheap but honestly not that bad compared to similar options. If you want a USASOC clone this is it but I could care less about that… it’s just a 100% reliable, highly accurate upper that comes with everything you need. Rest assured this thing is battle ready as soon as you slap it on a lower. I also have had zero issues with mine being “over gassed” as stated in an online review or two. It is just not under gassed and is technically on the higher end so it will run ALL ammo. It’s not as lightweight as a BCM or Midwest Industries but it’s so smooth and man I am telling you this thing is rock solid!

Came as advertised with a reliability enhanced BCG, G marked gov profile barrel and nano coated 4 prong. Upper shoots 1.5 MOA 10 round groups with 77gr, super reliable and properly gassed. 1k rounds in and wear is unbelievable with these premium coatings on the hardware,cleaning is super easy too. Could not ask for more and could not be more pleased. For an all-in-one package upper, it's hard to beat for 1400 considering the quality parts used here.

I purchased the Geissele URGI for my next build and the transaction could not have been simpler. Although "Availability" indicated approximately 13-24 days to ship, it actually shipped within a couple of days and I received the entire order within 8 days. The entire order arrived in perfect condition. Thanks to Optics Planet for such a great response!I will definitely use Optics Planet again!
