Umarex HK 416 A4 GBB Airsoft Rifle Field Test Review
In this Field Test Shooting video for the Umarex HK 416 A4 GBB Airsoft Rifle, I test it out to see what to expect in terms of velocity in fps by shooting several rounds through my Chronograph and averaging them out. I also shot the Umarex HK 416 A4 GBB Airsoft Rifle both in semi and full auto on a paper target setup 30 feet away to see if I can get a decent grouping in both semi and full auto.

Starting with power and velocity, I loaded up the magazine with as much gas as I could get into it, along with enough .20 gram Airsoft BB’s to average out at least 5 shots. I ended up using 6 shots in total for an average of 393 fps. Each individual shot was as follows… 427, 383, 368, 410, 406, 363 FPS. The temperature in the Indoor Airgun Sea Can Shooting Range was around 20 degree Celsius or 68 degrees Fahrenheit, so not overly warm or cool, In cooler or warmer temperatures the velocity will go up and down a little bit.
Moving on to accuracy, I first performed my test with the Umarex HK 416 A4 GBB Airsoft Rifle in semi auto to see what kind of 10 shot grouping I could get. I did not make any sight adjustments and just shot it right out of the box. My standard test is from 30 feet out shooting using a seated position in the back with my hands on a sand bag up front, this allows for a fairly stable shooting position. I did up the weight of my Airsoft BB’s to .25 grams which can help a little bit with accuracy, but I would suggest going even heavier with this Airsoft Rifle, perhaps try out .30 gram Airsoft BB’s. That said I was able to get a 3 inch 10 shot grouping that shot several inches below the bullseye I was aiming at, and just slightly to the left but not by much. I then switched over to full auto and probably should have aimed higher since this Gas Blowback Airsoft Rifle really kicks and moves around. Unfortunately most of my full auto shots went low and did not record on the paper so it is hard to say what the spread of the group was in Full Auto but I know it did open up a lot.
I really enjoy shooting and testing out Gas Blowback Airsoft Rifles since most are generally AEG and don’t have all the recoil and blowback action. GBB Airsoft Rifles not only look and feel much more real, that blowback action simulates the trigger feel and shooting experience so much more. Compared to an AEG velocity is less consistent not only between shots but as you shoot the gas cools down the Airgun resulting in slower and slower velocity which is even more noticeable in full auto when using a GBB Airsoft Rifle. I would personally use the Umarex HK 416 A4 GBB Airsoft Rifle mostly in semi auto as it shot very reliably in semi auto, full auto is a bit chaotic and your accuracy really suffers in full auto. The Umarex HK 416 A4 GBB Airsoft Rifle is about as realistic as you can get to experiencing a real steel AR type Rifle but it is fairly expensive at the end of the day and in terms of perforce you will get more out of even a middle of the road AEG Airsoft Rifle. So if realism is more important than performance and lower cost, I would go with something like the Umarex HK 416 A4 GBB Airsoft Rifle.
