5 of 5 Nice December 4, 2020
: David Fitch from Livonia, MI United States  
Received this barreled upper within the time frame promised by Mas Defense. Fitment was as expected on an Aero lower build. Excited to get it as fast as I did. It will be a Christmas present for my son. Will report back Ben we shoot for an update.
Thank you Mas Defense.
