5 of 5 10.5" 300blk upper 1:7 match grade complete upper April 19, 2019
: jeff a from florissant, MO United States  
This is a slow build so probably won't be on the range with this for a while but everything looks great so far. Installed this upper on its lower and it fit like a glove. No gaps. Pins aligned perfectly. Everything looks just fine. Looking forward to some range time with this.
Shipping was fast and Zach was great to work with.

4 of 5 Excellent upper receiver February 10, 2019
: Chris from Colorado  
Shipping time was accurate. When paired with a Palmetto State Sba3 lower reciever, tight fit at first but just like most parts, breaking in is required.  Upper is a little heavy, though that is due to the quad rail and me ordering the slim long flash can. At the range im not a pro but able to hit a target no problem. My wife actually shoots better than me with this compared to our 18in 5.56, will be ordering again probably will purchase a 5.56.

3 of 5 10.5 Blackout December 9, 2018
: Preston Bone from Clover , SC United States  
Im happy with my 300blk upper. It shoots good and havent had a single issue. The reason for the 3 star review is shipping was kind of slow and took longer than the 2-3 days as posted in the website.
