So I bought two of the items I put a link for above on airsoft taiwan.  I payed but my account says that it is unpaid and unconfirmed and therefore unshipped.  now I bought it today so there might be some lag between the servers.  idk.  Is it the website just not updating, I have heard of asian sites doing this sometimes.  anyone know what to expect.  just a quick question.

Try calling your bank or credit card company. They may be blocking the purchase because you are purchasing from china. I've had the same thing happen when purchasing from ehobby.

I apologize if this has already been asked, but does anyone know if the maple leaf hop up for the KRISS Vector work in the LM4?

It does? I'm getting several different responses. I made a thread on this, and was told if it was the product the poster linked me, then yes. He linked me to the KSC diamond hop up. I am asking about the legitimate KRISS Vector model, with the inner barrel and hop adjustment dial included. Does the EVO arm with it work as well?

Yes, it will fit, I used a Glock kit originally but I broke the tension arm and had to buy another one. The easiest way to do it was buy just the bucking/sheath/tension arm/e-clip package and that worked fine, just like the Glock kit. The downside being that if you buy the Glock of Vector kit you'll have useless parts left over that you've paid for.

I think I can live with the extra parts, if I can get anywhere near the performance people here have been getting. Thanks for the answer!

This kit give you what you need for the LM4, nothing more. I've ordered through them for mine, took a little longer than I'm used to but I had no issues with payment or shipping/getting what I paid for.

Vector uses the same exact hop up system so 100% yes the Eco kit for the vector has the correct arm and bucking

Well, just to clarify for some people, the EVO II kit for the Vector will fit the LM4 but keep in mind that the hop adjustment cylinder for the LM4 and the Vector are different, so with the Vector kit you will not be able to use the adjustment cylinder. Basically it means 'big whoop, so I just won't use that part' but of course just consider that with that kit you're buying parts that you can't/won't be able to use.

You may have to bend the tensioner arm down slightly. A lot of people have had to fiddle with it. However, I have a guy willing to buy a tight bore vector barrel to include with one he is selling, so I kind of win out.

So I broke out my LM4 for the first time in several months today. It was underhopping the BB's, and the adjustment hasn't really worked on this in awhile.

Decided to tear it apart, and as soon as I pulled the adjuster sleeve off, the arm fell out - broken!

What a disappointment... I have the OEM brass arm back on, and it's giving me the results I want... sort of, with bending of the arm to certain points. The accuracy and hop is fairly sporadic though. Going to have to buy another I guess.

I had the same thing happen to my first EVO II. I'm not sure if it happened during normal use or if it broke when I installed, but I do recall having to apply a LOT of force to get it all together for the first time. I noticed the same performance weirdness and finally opened it to discover that exact scene. I finally got another unit and an RA tech tight bore barrel to go with it, being extra cautious with the installation this time, and so far I am blown away by the performance. The barrel components were VERY tight on the RA tech barrel, but at least they're snug enough such that I do not feel it to be necessary to do the 'o-ring mod' as the assembly feels solid enough as it currently stands.

I have the maple leaf bucking/tensioner arm but when I look down the barrel I can barely see the ramp from the bucking. And all my teeth from my hop up cylinder are broken off. Will a guarded hop up cylinder work? Also what's the deal with the ramp? Have tried applying more pressure to tensioner arm. Maybe I need to order another kit

You'll need a kwa hop. The guarder hop is cut for the KSC type m4 GBB hop/barrel assembly.

The evo2 system in my gun is still running well...granted that I haven't used it much (cause I have 20 AEG's, GBBR's, & GBB SMG's).

I made adjustments like bend the tensioner and trim  the excess material off of it so bbs don't catch onto it. I have my lm4 shooting .28g bbs straight and far.

Unfortunately it's just a weak design on KWAs part. Since there is no pivot, the arm has to be flexible. You also need it to be stiff enough to apply force on the BB. If you've ever worked with metal you know you cant have both. I wish there was a hop-up chamber for the LM4 like Prime's WA chamber.

I've read a lot about the bucking and the arm but nothing about the cylinder. Does anyone tried the Maple Leaf ESD EVO II Hopup Housing???? It cost's arround 15$ will it worth the price?
http://www.wgcshop.c...s=MLTW-HH-KWAM4
As it's made by the same manufacturer as the bucking i think it shuold perform better than the original cylinder. It looks like it's made of cnc steel or aluminim, so i think i should be harder than the kwa oem part
If there is a post about this please tell me because i couldn't find it...

There's nothing really wrong with the performance of the stock hop-up housing. Most people that use the Maple Leaf or RAT hop-up housing, use it because they broke teeth of the one that came with their gun. Unless they bought a complete RAT barrel and hop-up, but i think that's self-explanatory.
