In this Field Test Shooting Video Review I mainly focus on the ASG CAA M4 Proline AEG Airsoft Rifle and put it through my typical velocity and accuracy tests I conduct in the Replica Airguns Sea Can Shooting Range. I do compare the ASG CAA M4 Proline AEG Airsoft Rifle to the ASG CAA M4 Sportline version since they look virtually identical but do have some notable differences, like the build materials and perhaps a few internal upgrades found in the Proline version. That said both ASG CAA M4 AEG Airsoft Rifles did perform rather similarly other than a bit of a velocity bump with the ASG CAA M4 Proline model.
So how did the ASG CAA M4 Proline AEG Airsoft Rifle perform? I placed 5 rounds through my Chrony Chronograph using .20 gram plastic Airsoft BB's and I got a very respectable 392 average fps with most of the five shots actually getting 392 fps so very consistent velocity for sure.
