WOW November 17, 2024 : Ryan B from Santa Rosa Beach, FL United States   I’m not sure what I was expecting as I was just looking for a budget home defense 300 blackout upper. The thing is, I have a lot of high and builds. One of my favorites are SLR rifle works. Mad Defense upper was perfect in every way. Screws were set exactly how they needed to be. All alignment was perfect, there were no blemishes, literally everything was as if I put it together myself. I will be a return customer. If you make some budget builds and go to Bear Creek arsenal or Palmetto State Armory… You need to be going here and ordering from them. Upgrade, in my opinion! Keep it up!

Very nice build February 24, 2022 : Marc Werner from HELENA, AL United States   This is a quality item.  Nice rifling in the barrel, gas block is set with two set screws and the barrel is dimpled for proper gas block alignment.  Quad rail hand guard is plenty large enough for most suppressors to fit under.  I would recommend a quick release suppressor as there are 8 screws to remove the quad rail.  Quality fit and finish on this item.  Highly recommend.

Pistol Build May 5, 2021 : Kyle from Goldsboro , NC United States   I’m working to put together a .300 Blackout suppressed pistol build and this upper seems like it will be a great fit. Barrel length is right and it will allow for some of the suppressor to be installed under the handguard. Fit and finish seems great, but I’m waiting on my lower. Can’t wait to have it all good to go!
