Thanks for the help guys. I've opened my rifle back up and disassembled the hop up assembly. The issue appears to be that once I put it back together, the nub is stuck in one position and is not adjustable. I bent the arm a very slightly small amount as was suggested and it did help. The .30 gram bb's travel about 100ft or so and then vere off. So, I will plan on using .32 or .38 as well. But, what can I do to make sure the hop up is adjustable once it is put back together. I don't want to break anything or weaken the tension in the metal arm by bending it too much, but it's designed to be adjustable and I fear that not installing it the way it's designed is just as bad as installing it wrong.

Take a look at the exploded parts diagram for the gun (its in the pro shop). That will give you an idea of how to properly reassemble the hop up so you can have full functionality of the hop up.

I've got the Maple leaf bucking in my hop up guys, but It's not adjusting at all and it's applying way too much hop. .25's go sky high.
I have no problem tinkering with it, I just think I installed it wrong and I am afraid to bend the tensioner too much and screw something up. thoughts? suggestions? Thanks.

I'm having the same problems as this guy. It doesn't matter how much I adjust the hopup, It won't change how much of the ramps are showing. I'm thinking I may have installed it wrong. Any suggestions?

You need to bend the arm so that it is only slightly bent upwards at the end (and also read the entire thread).

Given the number of people that have had problems with over-hopping, it sounds like there might be a flaw in maple leaf's design. They might have either made the adjustment tab too tall or the angle of the arm too steep. Can anyone compare the OEM hop-up tensioner to a stock maple leaf?

Just wanted to add my report to this thread:

After installing the EVO II (glock kit) into my LM4 I was concerned that it might over-hop a lot however I was very happy when my first mag of .30's today went straight as a laser. Everything cycled and feed correctly, hop was adjusted to the 'OFF' position, I have not bent the arm at all so I expect that maybe with lighter BB's I may have some issues. Full auto sent a beautiful stream of BB's dead on towards the wall about 150ft away. I think the range can be a little better, maybe if I give it one click or if there was less wind today I'd be able to tell for sure, but either way it's a hell of a lot better than the stock parts. Looks like I'll finally be running this gun this Summer, maybe I ought to put a red dot or something on there but for now I'm just ecstatic that it shoots well.

I wanted to add some information to this thread concerning the EVO II kit. I have the Maple Leaf bucking and the EVOII hop up tensioner installed with a RA-Tech 363mm x 6.01 tbb. Keep in mind that I am shooting pretty hot (~555 fps w/ .20's) ~435 fps w/ .32's. But with the proper install and "tuning" of this kit, it is possible to make some pretty great shots! This is purely for an example of what this setup can do: I made a shot (at another player) at a paced off distance of approximately 264 feet from a kneeling position. I was pretty impressed with the performance of the combination of these parts after struggling with the stock parts for some time. I just wanted to add this information to maybe help someone else who is also looking for a good combo of parts to make their LM4 perform.

I got mixed results with the ratech Tbb and evo II arm with maple leaf bucking. Some shots got great range (190 ft) measured but others fell very short. Using ksc 0.30 bbs. Hop up wouldn't make any difference.

I just swaped out the maple leaf bucking with a guarder and left the evo II tension arm installed. Will check results on tomorrow's game.

So how did the RAT barrel and guarder bucking perform?

So I did some more testing. I have not messed with bending the Evo arm, it's stock. Only switched to the guarder bucking. I saw that I was getting less fliers than with the maple leaf but no improvement in range. Shooting completely straight I'm not getting more than 55 meters measured (180 ft). I'm happier with this bucking since it's a little more consistent but I'm still trying to get more range out of my rifle.

My gun is shooting 400 fps with KSC 0.30. I would love to use heavier weights but the hop up just doesn't provide enough lift with the stock evo II arm.

Hi guys
Finally got to install this in my Asian LM4, along with a ratech TB
I was wondering if it was normal that the silver bucking sleeve (and bucking) was "protruding" like this from the outer barrel

When assembling the whole thing, everything looks normal but want to be sure.

The tensioner arm on the left is how it looks fron the factory..and is bent too much and this is why you folks who install this without bending it straighter are overhopping. The one on the right shows the small amount of bend needed to work properly with the maple leaf bucking

I'm getting massive and I mean massive over-hop. I tried bringing it down with heavy rounds but had uneven results. I can bet it's the arm bend is wrong. Thanks I'll take it apart and fiddle with it.

As an update and question: I've been using my LM4 with the EVO II for a couple games now and initially I was very pleased with the range and consistency however it has suddenly ceased to hop the BB's at all. The power is still there, the bolt cycles great, all the other functions are working very nicely. Did anybody else run into this issue? Any ideas on how to solve this or what might be causing it?
