Badass upper - Geissele USASOC AR15/M4/M16 Upper Receiver Complete Group

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!
