In this Field Test Shooting Video for the KJWorks MK1 Carbine Green Gas Airsoft Rifle, I checkout the velocity and power here in the Replica Airguns Indoor Airgun Shooting Range, to find out if the real world velocity is in the ballpark of the claimed 450+ fps velocity by KJWorks. I also shoot 10 rounds into a paper target from a distance of 30 feet to see how accurate of a grouping I can get. If you are interested in details, specifications and more close up video along with the Pro’s and Con’s for the KJWorks MK1 Carbine Green Gas Airsoft Rifle, then checkout my Table Top Video Review for it here.
Starting first with my velocity test, I loaded up the magazine with propane gas along with a full magazine of .20 gram Airsoft BB’s. The temperature was around 20 degrees Celsius or 68 degrees Fahrenheit, so not super warm or cold, in warmer conditions I would expect slightly higher fps from the KJWorks MK1 Carbine Green Gas Airsoft Rifle. KJWorks claims 450+ fps and my testing came pretty close to this with my five Chronograph readings hitting: 468, 451, 435, 436, 426 fps. Averaging 443 fps.
Next I made sure I still had 10 Airsoft rounds in the magazine and placed a fresh paper target 30 feet down range and shot all 10 rounds into the target using a semi rested shooting position, with my hands on a sand bag up front and sitting on a stool in the back. This allows me fairly stable shooting with less human factor. I did have to aim a few inches low on the center of the target as the KJWorks MK1 Carbine Green Gas Airsoft Rifle does shoot a bit high at 30 feet. 7 out of the 10 rounds hit all within about 2 inches of each other and then three rounds came out of the group increasing the 10 shot grouping from 2 inches to around 5 inches. I am wondering if perhaps I had some miss-formed Airsoft BB’s in the bunch as the shots that came out, really did come out a lot compared to the tighter 2 inch 7 shot main grouping.
Overall the KJWorks MK1 Carbine Green Gas Airsoft Rifle performed well, the velocity was right on the mark and was fairly consistent dropping off a bit as the Rifle cooled down from the gas. Accuracy was very good side to side but up and down I did notice more variation. The trigger is a double action only trigger so it is a bit longer and heavier than a real steel Ruger MK1 that is known for its beautiful short and light Single Action Trigger. Still the KJWorks MK1 Carbine Green Gas Airsoft Rifle performed well and I think with some good quality Airsoft BB’s, perhaps even a bit heavier than I used in this test, one could improve the accuracy at range and really be able to use this for some longer range outdoor Airsoft games. As it is a fairly light and short Rifle it would make for a super easy to pack around sniper rifle option.
Type:Airsoft Gas Rifle. Manufacturer: KJWorks. Model: MK1 Carbine. Materials: Metal and plastic. Weight: 2.71 pounds (1.23 kg). Total Length: 33 inches (83.8cm). Barrel Length: 17 inches (43.2cm). Barrel: Metal non-rifled. Propulsion: Green Gas. Action: Semi auto double action only trigger. Hop-up: Adjustable metal Hop-up. Ammunition Type: 6mm plastic Airsoft BB's. Ammunition Capacity: 17 round full size drop out metal magazine. FPS: 450+.
Trigger Pull: The trigger pull on the KJWorks MK1 Carbine Green Gas Airsoft Rifle is double action only which will make it a bit longer and heavier than the real steal Ruger MK1 as it is Single Action Only. The trigger is smooth however and does have a nice satisfying click to it that sounds like a firing pin being release. The unfortunate part is that the real steel version has an amazing single action only trigger so the contrast between the Airsoft and 22LR version may make this gun not as practical is an optional training tool if you own the 22LR version.
Accuracy: This part of the review is yet to be determined as I have not done my Field Test or Shooting Test for this carbine, so stay posted for my official Field Shooting Test. For now you can watch my Ruger MK I Gas version Field Test Shooting Review to get an idea on how the KJWorks MK1 Carbine Green Gas Airsoft Rifle version should perform, as they are very similar with the Carbine version having a longer barrel and shoulder stock added to it with should increase the velocity and perhaps the accuracy a bit.
Build Quality: KJWorks as usual distributes quality Airguns, the fit and finish on the KJWorks MK1 Carbine Green Gas Airsoft Rifle is very good and there is good use of metal where it needs to be like with the upper receiver, the inner and outer barrel, the bolt and other internal mechanical parts, the trigger, the safety, the rear fully adjustable sight and the full size drop out metal magazine that holds the Gas and the Airsoft BB's.
Realism: The KJWorks MK1 Carbine Green Gas Airsoft Rifle is based on real steel Ruger MK1 and looks very close to it for the most part. There is no blowback operation or bolt operation so that means that only a double action trigger is possible, this is a bit unfortunate since the real Ruger MK1 has an absolutely beautiful smooth and light single action trigger. On the positive side you can field strip the KJWorks MK1 Carbine Green Gas Airsoft Rifle just like the real version but you will need to remove the rear stock that covers the area you need to get to to field strip it.
Pros:
If you own a real Ruger 22LR you will be use to the design layout.
Adjustable rear sight for windage and elevation.
Metal hop-up for backspin tuning.
Full size all metal drop out magazine that holds the Airsoft BB’s and gas.
Satisfying trigger sound, sounds like a real firing pin a bit, not clanky like many other Airguns.
Full Metal upper and barrel.
Metal rear sight, bolt, trigger and magazine.
Non blowback helps with velocity and gas efficiency.
Field strips like original MK Series (will need to remover rear stock).
Cons:
No blowback so longer DAO trigger not like the real steel Ruger MK 1.
Some reviewers claim the hop-up is hard to adjust.
May be a bit too powerful for use in close quarters Airsoft games.
Comments:
The KJWorks MK1 Carbine Green Gas Airsoft Rifle is really just a modified MK1 Pistol by adding a longer barrel and rear shoulder stock to the pistol grip. I guess it is a good use of an already popular pistol design to give us a light weight and somewhat compact Airsoft sniper rifle for Airsoft games as it does have a fairly high velocity claim. Because of the high 450+ fps I would not recommend it to anyone playing in close quarters as it could injure other players so keep that in mind. If you are looking for a lower cost and fairly compact Sniper Rifle for some outdoor shooting, then it might be just the right pick for that. I am hoping my upcoming Field Test Shooting Video showcases it nicely so keep checking back for that Review Video down the road a bit.
This video was made right at the end of December 2024 but I am posting it in the new year so we will call it a late December video… That makes two Mystery Box Videos for December 2024 which means a lot of new products on my plate to review this new year.
