5 of 5 Great complete 300 blackout upper! April 5, 2023
: Nathan C from Naperville, IL United States  
I bought the 7.5” Nero blackout upper. I use a normal
buffer spring and normal 3 ounce buffer weight and this upper cycles 124 grain to 147 grain supersonic ammo! Using a nickel boron BCG too. Perfect right out of the box!
