In this Field Test Shooting Video Review I mainly focus on the ASG CAA M4 Sportline 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 much lower cost for the ASG CAA M4 Sportline AEG Airsoft Rifle. That said both ASG CAA M4 AEG Airsoft Rifles did perform very similarly other than a bit of a velocity bump with the ASG CAA M4 Proline model over the Sportline I test in this video.
So how did the ASG CAA M4 Sportline AEG Airsoft Rifle perform? I placed 5 rounds through my Chrony Chronograph using .20 gram plastic Airsoft BB's and I got a 335 average fps which is a bit lower than the ASG CAA M4 Proline AEG Airsoft Rifle but still great for a variety of Airsoft shooting situations. I did notice that the FPS seemed to be creeping up slowly as I tested it, maybe some break in was taking place?
Moving on to the accuracy portion of my indoor field test, I place my paper target 30 feet down range and put 10 rounds into the target shooting from a rested seated position with a sandbag up front. The ASG CAA M4 Sportline AEG Airsoft Rifle shot a nice 1.5 to 2 inch grouping a little to the right of the bulls-eye and slightly low, which I can easily correct using the adjustable sights and hop-up adjustments. I like to conduct my field tests with all the guns right out of the box and with no adjustments prior to my testing since that's the way you're going to get them and you may have to also make some small correction to the sights and or hop-up adjustments.
In full auto mode the ASG CAA M4 Sportline AEG Airsoft Rifle didn't miss a beat. I emptied what was left of the mag (About 130 rounds or so) in no time with a few quick bursts making a nice mess of the paper target which is the result I'm looking for in full auto mode :)
All in all the ASG CAA M4 Sportline AEG Airsoft Rifle is a decent quality Airsoft gun at an affordable price-tag. If you're budget is a higher than checkout my previous Field Test Shooting Video of the higher end ASG CAA M4 Proline AEG Airsoft Rifle.
