@Maximusmjg.... You said you're using an RAT 6.01 tbb. how did you get the tensioner and c-clip on??? I just snapped the tensioner and had to reorder another set (hop up, sleeve, and tensioner) from ebairsoft. The sleeve seems to cover up the rest of the space that's shaved onto the barrel for the tensioner and clip.
Mine went right in just fine, I didn't  have to do any mods at all for it to fit. I took the old assembly off and just put the KSC2 kit right with no problems.

Besides bending the tensioner arm has anyone tried anything else to stop this kit from over hopping 0.25gs? I've tried bending the arm, sanding the top of the bucking and 0.25g can go straight about 150ft, but then curve off up and to a side. I was thinking of taking some 1k or 2k grit sand paper and taking off some of the inside. I've also been messing with a tensioner that has the bump broken off (oops) so the end looks like a stock arm.
Any ideas or results?

I would in no way recommend sanding the inside of the bucking. Though the big question is, why not use a heavier BB? Even stock .25g is the borderline of performance as it likes heavier BBs.

Ive sanded the inside of the r-hop for my AEG and it works extremely well. Definitely different material though. But my 340fps aeg is definitely more accurate and predictable than my lm4c at around 350fps. As for lighter weight BBS, I feel like the flight time does make a difference to me.

Huh? A heavy BB flys further with the right amount of energy behind it. And the LM4 has that energy. A lighter BB is harder to stabilize. Listen to these guys they really do know what they're talking about.

I think he might be referring to how fast the BB gets to the target, but the way I think of it is that it doesn't matter how fast the BB is going if if won't hit the target every time!

I'm sorry if I missed this in the thread.  For those of you who have bought the EVOII - Partial Kit - Bucking, tensioner, and metal airseal, was this a direct drop in to the OEM Hop-up?

Pickle I agree! As Kevin Schwantz once said speed without control is useless...or was that Kenny Roberts? Either way it's so very true. If the BB is traveling at 300FPS and dead center that guy will wax a squad running guns hitting 600FPS but only hit 1 in 20.

Checked my lm4 and found that the back tip of the steel tensioner had some debris on it from bbs. It may be possible that bbs hit it while being loaded. As it is excess material...I decided to sand it down. Lm4c currently shoots around 370 fps with .20g bbs. I feed it .25g tracer rounds. Current set up requires for me to turn the hop three clicks up for the said .25g bbs to shoot straight with minimal over hop. Its probably as close to being perfect as I'll be able to get it. This guy is a happy camper.

Any other modifications to the internals of your LM4c? What's the approximate range?

Id say range is on par with aeg's when it shoots its farthest (slight over hop). When the bbs somehow do not get enough hop...id say that it still gets a good 150+ feet. Unlike aeg's, shots are definitely more unpredictable. Some shoot up to 200 feet....others drop to 150+ feet. These are of course guesstimates. All I can say with certainty is that some of the shots go as far as an aeg...gun is not as consistent as aeg's but it will be competitive especially in cqb fields. Ill have to field the lm4 outdoors then decide.

I posted a video of the kriss being used outdoors. You guys can see that the kriss v is able to make some pretty darn far shots with pretty good accuracy. I don't see why the lm4 shouldnt be able to do the same thing outdokrs.

OK, just ordered the kit, minus the barrel, to install into my LM4.  I'm thinking I might drop in the KM Head to see what I get for results.  Will keep you all posted regardless.

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.

In my case the arm is straight aside from the end section being slightly bent upwards (the section with the hook on it that comes into contact with the hop up adjustment shell). Keep in mind that I am shooting around 430-437 fps with .32g bbs. (555 fps with .20)

So, just worked my way through this thread, planning my (eventual, grumble grumble job market sucks grumble) LM4 build, and I'm trying to clear something up in my head. Between the TBB, Maple Leaf bucking set, and a DangerWerx valve on a standard-length LM4, the gun should still shoot at something close to stock FPS, right? I thought it would, but, uh...

...there is no field or regular event in Michigan that I'm aware of that would let me take a gun that hot out. Hell, there are a bunch that mandate 350 or less with .20s, and I'm not just talking CQB fields.

mileage may vary. i'm spit balling here,but maple leaf may affect fps +\- 10 fps, DangerWerx valve (unmodded) may drop around 60-100 fps (i've heard different reports, personally mine dropped about 70fps), tbb may raise fps approx 30-50fps.

It's a lot of modding, then testing.  I hope you have a chrono handy.  I suggest getting the tbb and maple leaf first as they are pretty much setting your baseline and not adjustable (unless you plan on cutting down the barrel).  Later, you can mess with your spring/valve combination to fine tune your fps.

FYI I'm running a 260mm ra tech ttb, maple leaf evo, shaved dangerwerx valve, cut valve spring, and i'm at 350fps with 0.20g, with some power creep as you go up in bb weight.  Same setup with a stock valve and valve spring shoots roughly 380-390fps 0.20g,  

I never ran the full length ra tech barrel, so I can't confirm how much it actually affected fps.

They also make a LM4 rocket valve now from DangerWerx, it's pretty muched a MP7 valve that's already been pre shaved looking at pictures.

I play exclusively in private games where the players are all shooting around 450-500 fps (outdoors). I have shaved the stock rocket valve, a lot, and stretched the corresponding spring, slightly. Also, keep in mind that the heavier bb you use, the greater amount of power creep you will have.
