A truly radical build idea right out of left field.

Has anyone here heard of the Ruger MKI Carbine?

Well I have a theory I want to test with this rifle.
I want to turn it into a legit low power, high range rifle.
I had this idea while looking upinfo on how to drop the FPS and increase the range on this rifle. My interest was peaked when I came across a post on TK Twist inner barrels.
This post to be exact: http://www.airsoftforum.com/board/TK-tw ... ry18440557

For you skeptics and those that don't know, TK twist barrels are basically inner barrels with a form of rifling. Rifling in a real steel gun actually makes contact with the projectile. The point behind the TK twist barrel is to provide a turbulent "air cushion" around the projectile to keep it from bouncing around within the barrel thus makeing the bb's shot path more consisant. the negative is that TK twists only really work on 330- fps rifles. Any stronger and the effects of the TK twist start to be negated, worse off even, the opposite effect results (explained in detail here: http://www.airsoftforum.com/board/Tanio ... 47334.html)

Anyway, what piqued my interest in the post was the comment made by Grady the Scot in which he said this:

I am still of the opinion that fps in the US is getting overly inflated. A lot of people don't know, but Japan didn't have fps restrictions when airsoft was born. They did the same thing we are doing now. Their fps went up and up and up until people started getting seriously hurt and the fps laws were put in place. When I first got into airsoft years ago the standard fps was high 200s low 300s. I remember getting my first AEG and we thought the fps was really fast at 340 fps. Then a two years later stock aegs come clocking in at 400 fps. Every clone company selling to the US had to beat its competitors in the FPS race or they just couldn't sell guns. Now my friend who has just gotten into airsoft decided as soon as he got his very nice 400 fps gun that he wasn't satisfied and he needed his AEG to shoot 500 fps! This is getting ridiculous! I play in woodland exclusively and my weapon of choice is my 320 fps P90. With at TK twist in there the gun shoots well out to 250 ft. With all the bbs coming out of the gun it is much more effective than a sniper rifle and at 320 fps (with tk and good hop up) I'm outranging all of those clone 400+ fps guns.

After finding the info on how to downgrade the FPS (special thanks again to Undead and fallout11 nd his old teammates ) I had originally planned to downgrade it to 380, but after finding the posts on TK twist I figured I'd try my luck downgrading my FPS to around 320 and popping in a TK twist. This sparked another idea in my mind to place O rings on the innerbarrel to steady it further and increase the accuracy even more. An idea which came from the Echo 1 M28 (broken down here: http://www.youtube.com/watch?v=NK6cCcOi ... r_embedded)

Normally I would call this skeptic just as you guys are probably calling it right now, but after learning of Flat hops and other instances of methods that allow airsoft rifles to reach distances of 300ft, I figured I'd give it a try. If this doesn't work I'll just go to my original plan of downing it to 380 or so.


This is a pretty random, out-of-left-field idea but if anyone is interested and/or has ideas to add or critisisms, feel free to post them. This seems like a fun, really creative project.

I think if it works, you will have one JAM UP scout rifle.

[SteevoLS]

You probably won't get 300 feet out of that build, but you will certainly have something in the mid 200s. You're still left with a pretty crappy hopup chamber and a horrible trigger pull.

That's what I'm counting on. Low to No med long reaching scout class

FPS inconsistency does not play nicely with your plans either.

I wasn't expecting 300ft nd the plastic hop up was bad. The metal hop up version has a pretty decent hop up. And I can deal with the trigger pull. But if I can make it a git softer, I will work on that.

I have a better idea. Take whatever money you plan on spending on that fugnasty gun, and burn it instead.

and your grounds kind sir?

[Akaishinobi]

Exactly.

Gas guns don't have fps consistency. At least, not the gun you are wanting to use. Your fps consistency will be one of the most important things that you'll need to work on if you go through with this. The thing about that, and this gun, is just because you can hit out to 250ft doesn't mean you'll do so with every shot, the fps variance that you'll get with gas will cause a large range variance further out.

I also question the ability of Twist barrels. I've not seen results that suggest they are better than any other nice aftermarket barrel. As a matter of fact, the results that I have seen all say the same thing, they are all the same. You see, the barrel doesn't have much to do with range and accuracy. There's a point where it just doesn't make any more of a difference in accuracy. It all comes down to the quality of your hop up. I would spend more time looking into making a quality hop than to spend the money on a TK Twist barrel.

250ft of range is possible with a flat hop and a 320fps gun. Using the gun at 380 means the use of heavier bbs, and heavier rounds.

Grady the Scot has a point, but is wrong at the same time. Yes, a quality hop up will get you shooting way out there, regardless of fps, but fps still plays a roll in range. You think these clones have quality hop ups in them? It's silly to compare an upgraded P90 to a stock clone gun. Upgrade both and the one with the higher fps will shoot further. Other points that he has overlooked is brush penetration. In all fields with brush, harder hitting guns will have an advantage. The more energy the bb has, the more likely it will be to penetrate brush and get you your hit. 320fps is almost nothing, even with .25g bbs, going through brush will be difficult, especially with a gun limited to semi auto. There's a reason semi auto guns are allowed to have a higher fps than that of full auto guns. Just because you are dead accurate, if you are only shooting 320fps, you will be very hard pressed to get a shot through that bush. Thirdly, people can hardly feel a bb at 200ft that left the muzzle at 320fps. The bbs are floating at that distance with that speed. Even the most honest of players might not call their hits because they simply didn't feel it or hear it hit them.

I understand what you are doing here, I just want you to be aware of the options, and the disadvantages it will give you on the field.

Not really thread jacking, because this is relevant, what exactly is flat hop?

[Chippy]

It's a hop up mod. Kory has a whole thread about his work under services for sale or something.

[Bishop]

It's a hop-up concept that was designed primarily by Star_folder with some other techs inputting some ideas. In short it significantly increases effective range of airsoft guns, and its the best hop up change next to the R-Hop which is a much more complex concept.

I know it's a hop up mod...
Thanks for the link, I'll check it out.
