K so I decided to go with the 2Roy hop up kit instead of the best gun cuz BG is absolutely nowhere to be found and no one (evike, tokyomodel and airsoftshop) will give me a definite answer as to when it will come in. therefore, I have also decided to get a 6.03 590 mm barrel and have it cut down to fit the stock tanaka m40 length. I need some suggestions on which barrel to get. I found this one on airsplat that's obviously cheap. how does it sound?

Get a VSR 554 or 555mm length barrel. I got the cheaper $50 laylax one and it works fine.

and it works? the tanaka is like a 584mm. how'd you compensate for the shortage of length?

the 2roy hopup kit is the same as the king arms conversion kit isn't it? it comes with a different endcap to compensate for the shorter barrel.

Also it makes the gun louder evidently.

so if I got the 2roy and a 555mm vsr barrel I'd be all set? no problems with it being shorter than the stock barrel?

Yep. That'll do.

You'll also want to get a hopup rubber. The kit doesn't come with one and it's absolutely required. I suggest nineball. I, and a few others evidently, have all had problems with the KA rubber.

Yep, go for the Nineball rubber instead. The KA one doesnt fit very nicely in the chamber.
I got a 639mm Edgi barrel in my tanaka.
When I got the KA conversion kit, the endcap didnt fit in my outer barrel, it was too big. Then I decided to drill out the stock one and that worked just perfectly.
Now im just waiting for the Ninball rubber so I can see how it will perform.

my KA rubber got mashed up by the bolt. I had to take it out and use a drill to clear all the frayed area, and smooth/round out the inside again. It works pretty well now but I still think a new, un-mashed nineball will work better.

This whole hopup unit is incredibly consistent too. I think it's in part the fact that the piece pressing down on the rubber is metal, as opposed to the tanaka's which was rubber. I was hitting an 6 inch wide tree ~180 feet, 8 out of 10 shots with KSC 0.28g bbs (that's all I had left. They're not the best for tanakas.)

I don't know why you would ask that since we already said the 2roy is better. I think I saw a post like this on the forum. 2roy is better but why a 6.03. Most snipers like 6.00 or 6.01 barrels in their rifles.

alright it's settled then. I'm getting a .03 cuz I can't afford the .00 or .01 atm. it won't end up costing me that much less if I get a DBC cuz they'll have to customize it too

At first I bought the KA bucking, but I never got the chance to try it out due to the fact that the nozzle that comes with the KA conversion kit, ripped my bucking apart.
Now I got the nineball but I havent got the chance to try it out at some longer distance.

Nineball:
Air seal gives best shot-to-shot consistency
Soft type provides less range for a rifle over 400 fps on .2g

FireFly hard:
No air seal can cause a lack of consistency between shots
Hard type bucking adds considerable more range than the Nineball

King Arms:
Mix of the two; has an air seal and is a hard type bucking.


Im not sure wich one is the best, but I would go with the KA bucking. I read many good things about it before.
Be careful when you :censored2: ur rifle after changing to the VSR conversion kit though, cause im sure your nozzle is also too big for these tight buckings. File the edges down a bit on the tip of the nozzle and you will get a smooth cocking action and your rubber will stay intact.

k so how much do I file down the edges? and where does the bucking go, just under the metal bucking part that's shaped just like it?

Just use a common file.
Sorry for my bad english, but I don't know what you are talking about when you refer to the bucking.. a-jester.gif
You do this work on the nozzle so it can penetrate the bucking without ruin it.
When you get the kit, you will see how sharp the nozzle is.

k so I got the 2roy but didn't get to install it cuz I need the bucking but here's the important part: the 590mm barrel worked with the 2roy. the endcap replacement that they give you doesn't have a lip, it just covers more ground in the barrel, allowing you to use a shorter inner. it acts like a barrel spacer too which is nice. with the 2roy, you could use a 650mm psg-1 barrel, but you'd probably have alot hanging out the end of the barrel. either way, the 2roy and a 590mm inner work together. I'd say the only possible issue would be inserting the endcap. you have to insert it through the muzzle which means you have to push it down onto the inner barrel for it to work. I'm guessing it's possible for you to rip the hop up rubber doing this since you're basically pushing the inner barrel back into the hop up.

Sounds interesting..
I have the Tanaka M700 Police model, and I think it has longer outer barrel than other tanakas. I just remember that the endcap that I got with the kit, didnt fit at all in my outer barrel. It was too big. Thats why I now use the old one instead.
However, im not sure if this is the problem I have experienced, cause I tried to take a bucking and just place it over the nozzle and even though I have filed downed the edges its still tight over the nozzle.

But please post here again when you have received your bucking and you have installed everything.

well you gotta insert it through the muzzle, not the end that screws into the receiver. I'm assuming you tried it through the muzzle. it might take a little bit of work to fit it in? I can't say for sure cuz I haven't had experience with that gun. I'm pretty sure you still need to dull the edges of the nozzle. I'm gonna do that as soon as I get my old on out and figure out which side is front and which is the back
