KJW MK1 Carbine

I was lookin around for a new gun to use with my friends, we go out and play in a huge graveyard and ive been using a Co2 powered Crossman, its been getting kinda hard to use without hopup and the range aint great so i was lookin and saw this KJW MK1 Carbine for $94 on www.airsoftatlanta.com with great stats can someone tell me the truth about it?
P.S.- What Gram BBs do you think i should use with it .25 .30???

This is a decent "rifle" for under 100 bucks. Most sites that feature it say it has outrageous fps, in and around 500, more if you can find and use red gas. Due to this, I would get a heavier bb to make sure you get the best accuracy out of the deal. A .3 gram bb would be my first choice as it will only drop the fps down to like 420 or so but that is still a beastly speed considering this is little more than a pistol with a stock and an elongated barrel. For such a powerful gun, I would think you would be aiming at people about 30 yards away so a heavier BB would make it less wind-steered and have the groupings tighter at that range than a .2-.25. I would not go below .28's with this gun. Its a semi-automatic so it'll fire as fast as you can shoot and its a non-blowback so you'll have the best gas economy possible. KJW is not the top of the line as far as gas guns are concerned, but they still make decent guns. I own a KJW Baretta gbb and its worth the money I paid for it and hasnt given me a problem once. I dont think any other brands offer this model either, to my knowledge. I dont own the mk. 1 but I have seen it in action and I think if you have the money and it seems like a good buy to you then go for it because it is a durable and powerful weapon. I would get an extra clip as well as make sure you keep that barrel clean and lubed. If you wanted more of a sidearm then i would get the pistol version, but if you wanted more of a shoter sniper rifle that is a semi-auto then this could be a good choice for you.

Also i have never used a gas gun before, so do you have to have a Propane Adapter, Duster Adapter, and Silicone oil to make it work right or can you just buy a can of red gas and push the nozzle into the clip to fill it?

I would get green gas canisters and not have worry much about lubing or smell (propane doesnt smell like roses) BUT since its a non blow-back and you wont be smelling excess exhaust from the blowback of a slide you should just get a propane adapter and a can of silicone lube. Get the propane from any hardware store/department for like 3-4 bucks and you'll spend less on gas. This gun will go through gas a lot less than most guns so you should be spending a lot less if you go that route. I would lube the barrel every month, clean it with a cloth if you have the tool for it, and then after a heavy use spay a tiny bit of silicone into the rubber well at the very top of the gun while depressing that metal nub and inch down the front of the clip. This will lube the inside of the clip which will make a better seal and make your mag last longer. Also spray a tiny bit into the fill nozzel every once and a while. Thats taking care if a nbb 101. If you need to know anything else about non-blowbacks or blowbacks, I have a lot of gas gun experience so feel free to PM me or post it in the topic. PS: I dont know what a Duster Adapter is but if you mean a can of compressed air to spray down the barrel, etc. I would not reccomend it at all.

Why should i not use red gas now? and is red gas more powerful then green gas and i am still confused if i get the propane adapter do i still have to use gas lol (im not very smart)

Red gas is more powerful but it can sometimes break guns.

If you get a propane adapter will will just use propane, but you will have to lube the gun. Overall, propane is a much better deal. The adapter pays for its self the first time you fire a canister of propane. (Not quite, but almost)

Oh ok, i guess im gonna go with propane since i sell propane grills( i can get the stuff for free!)

^^ Well, its not exactly the giant propane tanks you hook up to your grill. These are smaller tanks that you would take on the road per se. They cost 3-4$ at a hardware store, so they are not very expensive at all anyway.

You can still use red gas if you want. Because its a non-blowback it wont hurt the gun even if its plastic, but you'll be pushing 550-600 fps so be careful. Red gas and propane dont have silicone oil mixed with it like green gas does which is why you would have to lube your gun every once in a while. Also, the reason you want to use the small canisters of propane is that you have to invert the tank upside down to fill the magazine properly. Not so easy with those larger tanks.

So when i want to play with friends can i use propane and hopefully that will take a chunk of the fps?

With propane you'll still be averaging 500 fps +/- 20 so it will still make your friends scared of you. Just buy extra clips because you dont want to refill the gas, or the bb's for that matter, right in the field esp. if you are using the mk1 are your primary.

How do you know when the clip is full of propane?

and do you have to refill with propane every clip? and anything about propane leakage?

The clip is full when its full. There is no real way to know its topped off other than to hold down the gas for a longer time to make sure. A clip that size will usually be full in about 2-3 seconds so count 5 mississippi's and youll be good every time. You dont have to use propane every time, but before switching to another type of propellant make sure to empty the clip completely before filling with something else. Leaking usually is due to a damaged fill nozzel, but sometimes it can be the flow valve too, regardless of propellant type. If you hear a hiss when holding it to your ear after a complete fill, you will want to replace the nozzel/valve or just get a new clip and save yourself the hassle. Leaks, besides making your clip run out of gas in a blink, are dangerous as well so dont continue using it.

Everything said are good points to ponder.

I will only add that as OMD stated, the value of using propane is infinitely higher imho than anything else.

There is of course the unpleasant smell, but small sacrifice, considering the savings.

Also, many retailers have been forced to stop shipping the non DOT approved Green/Red gas cannisters therefore, supply has been short of late. (Meaning that you have no option but to use the Propane option).

As for knowing when the Mag is full. If you listen closely you'll hear the hiss of the gas from the high pressure tank to the low pressure magazine.

Once you stop hearing the hiss...the pressures have equalized and the mag is as full as you'll be able to get it.

Propane and the gasses mentioned are effectively the same (At least that is what my research tells me). As stated already, the fancy gasses include silicone lube and "Air freshener" to make it smell better.

Once you get the hang of using the smaller "Camp stove" propane bottles, there is really no problem in making quick refills.

One word of advice, dont OVER LUBE the gun.

Follow the instructions and remove the propane adapter every 4 -6 fills or so and spray the silicone into the adapter.

Just spraying it into the mag well etc...can result in lube everywhere and eventually could cause the gun to start "burping" or not fully cycling. (More of an issue with blowback models).

Best of luck!

I purchased a MK1 Carbine a couple of months ago, not to shabby for the price. As with any gun, you'll have to correct the hop-up, etc, and you can add spacers to the main spring to get more velocity out of your mags. I took my friends old UHC Super X-9 (POS!!), gutted it, and nested the MK1 inside the Super X-9 body. Now it's a beastly sniper, shooting around 550 fps using 30g's. Never tried red gas, but right now it's a death sentence from 120ft easy.

Wow I didnt even think that was possible. I'd like to see an image of that in the pictures section if you can. Also, what spring are you talking about, the one in the magazine?

Here's a more detailed synopsis of the spring: http://www.teamblackjack.com/ttr/mk1vel.htm

I'll post some pictures soon, right now my camera is busted. The Super X-9 comes with a scope, rails, and bipod. Essentially remove the firing mechanics from the Super 9, leaving you with just the ABS body, dremel the frick out of the bottom so the MK1 sits inside with the handle/clip/and trigger coming out below, secure it and presto! Mount your scope on the MK1 and use the lower rail on the Super 9 body for the bipod. Your old Super 9 barrel will fit over the MK1 barrel, which produces an interesting sound, or you can order the 23" tight bore barrel for the Mk1, otherwise your sniper will look kinda snub nosed. As with all airsoft mods, when done correctly and patiently, this is a great mod, when done quickly and sloppily it will look like poo. I'll post some pics soon.
