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.
Type: Pellet Pistol. Distributer:Umarex. Model:Stainless Ruger Mark IV. Materials: Metal and polymer build. Weight: 1.56 pounds (708 grams). Barrel: 5.3 inches (135mm). Total Length: 11 inches (279mm). Propulsion: Spring Piston. Action: SAO Break Barrel. Ammunition Type: .177 caliber pellets. Ammunition Capacity: 1 round. FPS: 320.
Trigger Pull: The trigger pull on the Stainless Ruger Mark IV Break Barrel .177 Cal Pellet Pistolis not too bad, I feel it is a around 6-7 pounds or so without measuring. In comparison to a real steel 22LR semi auto SAO trigger pistol, the trigger is much heavier but most of these 22LR pistols of this nature have what I would consider to be near perfect triggers. Over time once you get use to the pressure and release point accuracy with this pistol it is for sure possible.
Accuracy: I have tested out the all black version of this pistol which will perform exactly the same or should I say is expected to perform the same since they are virtually the exact same Pellet Pistol but in different finishes. You can watch my Field Test Shooting Video for the all black version but in case you don’t make it there I will fill you in on the basic results… In terms of velocity I averaged 312 fps using 7 grain lead pellets and got around a 2 inch 7 rounds grouping but expect with a bit more trigger time to get closer to 1 inch.
Build Quality: The Stainless Ruger Mark IV Break Barrel .177 Cal Pellet Pistolis a low cost target plinker that also doubles as a licensed Replica for that coolness factor so you won’t get an all metal super top quality build here. That said metal and plastics are well used and for sure details in the fit and finish have been improved over the Buck Mark URX version where I found the barrel felt a bit sloppy and the trigger was plastic. The Umarex Ruger Mark IV Break Barrel .177 Cal Pellet Pistol has a much tighter barrel fit when closed and the trigger is now metal! Maybe Umarex watched my video back in the day and took some notes?
Realism: The Umarex Ruger Mark IV Break Barrel .177 Cal Pellet Pistol most resembles the Mark IV Hunter edition and is pretty much bang on in terms of being a replica other than the tell tail hinge just under the barrel required for a spring piston design, there really is no way to get around this so I’m not going to criticize this minor difference. The real steel version is almost 3 pounds and so the pellet shooting version is a bit under weight so it would have been to have had more metal perhaps in the barrel and lower frame. Again since the pellet shooting version is a springer you will not have any working bolts or slide catches or a built in magazine.
Pros:
It's a decent Ruger Mark IV Replica!
Feels well built overall.
Expect it to have really good accuracy like the Umarex Browning Buck Mark URX since they share similar mechanical design.
Barrel locks into place much better than the Umarex Browning Buck Mark URX did.
Fully adjustable rear sight with fiber optic front sight.
Auto locking safety, just don’t forget to unlock before each shot
Actual metal trigger in this version.
Nice and compact, not too heavy.
Full Ruger licensed via Umarex.
Fairly low price tag.
Cons:
No built in rail for a sight system like the Umarex Browning Buck Mark URX.
Would have liked a metal trigger and maybe a slightly lighter trigger pull to match the real Buck Mark's very light trigger pull.
A bit more metal would have been nice.
Significantly more expensive than the black version which is the same exact gun in a different color.
Comments: The Stainless Ruger Mark IV Break Barrel .177 Cal Pellet Pistol is a decent looking replica and a decent pellet shooting target pistol and if you own the real steel version in 22LR you may just want to get your hands on one of these Break Barrel Replica Pellet shooters. The only real question is do you get the Stainless version with simulated wood grips or the all black version? If you like the look of the stainless version and don’t care about money whatsoever, then pickup that one up since it is a Limited Edition version that will only go up in value over time. If you are on a budget and don’t mind the look of the all black versions or maybe even prefer it then by all means grab one since at the end of the day they will both perform exactly the same.

Accuracy: I have not had the chance to really test fire this pellet pistol but will be doing so next week when I make my Field Test Shooting Video for the Umarex Ruger Mark IV Break Barrel .177 Cal Pellet Pistol. If it is anything like the Umarex Buck Mark URX which I imagine it will be, then I am expecting to get some good accuracy as the URX was able to get a nice under 1 inch shot grouping when I tested it a few years back. Velocity I am expecting to be up and over 300 fps even using lead pellets, I am hoping it will be in the mid 300’s

A bit more metal would have been nice to get the weigth up closer to the real steel version.
Comments: I remember the Umarex Buck Mark URX being a super fun pellet pistol to shoot even though it is only a single shot airgun. Sometimes just getting back to the basics and taking your time to really place your shots and see how accurate you can be is more fun than spraying BB’s and pellets rapid fire and hoping you hit something. The Umarex Ruger Mark IV Break Barrel .177 Cal Pellet Pistol is inexpensive to buy and inexpensive to shoot, no CO2, just a tin of your favorite pellets and you will get hours of fun for it while honing your shooting skills. And at the end of the day the Umarex Ruger Mark IV Break Barrel .177 Cal Pellet Pistol is not a bad Replica Airgun if you are a collector of shot guns.
