Maruzen L96 hop up problems

[zman244824]

I just traded my M4 Aeg for a Maruzen L96. I took the hop up off the barrel when the bbs started to shoot off to the right and I figured a needed to re-align it. When I put it back together I cant seem to get it to work, I have the hop up all the way on and it still curves down. If anybody has some insight on how to fix this feel free to post.

Blag, BoredKender, and Livonia all have real experience with those guns. The hop-up was the issue I mentioned it had in my sale thread. I had hoped it was just the hop-up rubber or nub, but I never really took it apart to look at it. If you want to get upgrade parts, order from here: www.x-fire.org/etop/t96.html

The hop-up will allow you to use AEG barrels, which are much cheaper.

Just a thought, but one of those guys I mentioned above will probably see this soon and be able to chime in.

To be honest I haven't messed around with A stock Maruzen hop chamber in a long time. What it sounds like is that you lost the nubbin, its a small rubber piece that puts pressure on the bucking when you adjust the screw.
What I do remember is my original hopup chamber breaking the first time I took it apart. The chamber is brass, and there is a steel plate connected to it which is what you attach the mag catch screw into. This piece is not fastened well to the chamber and comes unglued or whatever it is very easily, rendering the whole thing useless. I have now been through two PDI hopup chambers due to old mag catch screws getting flexure from the magazine spring pressure and breaking off inside.

Here is something I came across not too long ago, very cheap, but will probably cost just as much as a new PDI hopup chamber because of shipping, except your getting a very low quality product.

These are really old pictures, and took a good amount of time to find but... this is a PDI unti, somewhat like the stock chamber but the PDI utilizes arms instead of a wraparound piece of plastic.

The top of the chamber, just pulled from the outer barrel.


O-ring removed and arms lifted, showing the clear silicon nubbin nestled in. This is the small piece I'm afraid you lost, which is vital to the whole thing. If you do not have one of these, its what your missing. You can make one of these by snipping off the end of the ink tube inside a pen, may cause your gun to have excessive hop because the tube is hard, but you should be able to tune for it.


Next is the whole thing apart, you can see the nubbin next to the o-ring.


If you still cannot figure it out and live anywhere near Livonia, I'd be happy to help you fix it. I refuse to hear of a Maruzen going to waste. What I'm curious of is why it started to shoot inaccurate in the first place, what kind of BB's were you using?

The hopup is the notorious weak point on the L96 platform. The stock hopup is just shy of worthless, especially in a high fps setup. Go with the PDI chamber.

That's funny.

[Livonia]

Providing useful knowledge to someone who need it is hilarious...

[PlastiKTuneR]

No, Not what I meant.

[Mles]

Then why don't you tell us what you meant.. Your obviously not contributing at all.

[BoredKender]

I am going to assume he (being a UTG L96 owner) is taking a cheap shot at the fact that the Maruzen L96 has a weak point. If this is the case, he likely does not realize that I said the L96 platform, not Maruzen-specific. The UTG has similar (and worse yet) hopup problems with the stock unit.

[Livonia]

Hes probably disappointed about PDI chambers costing a third of his rifle. Perhaps maybe the fact that a chamber, bucking, barrel spacers and descent tightbore cost as much as his whole gun, and these are the things you can't even see externally. Better yet, a typical scope and bipod setup, which comes free with his, is as expensive as the whole UTG MK96 player package.

Quality, its what holds a Maruzen together.

[PlastiKTuneR]

You guys just made my day. rofl.

I finaly fixed the hop up by cutting a square piece of soft headphone rubber as a make shift nubbin and now I got the gun shooting straight at 200 feet

[Punisher]

I'm suprised that works. I cut a piece out of one of my skull candy replacments and it doesnt work.

SR25, Try a rolled up piece of electrical tape cut to size.
Also, be weary of the dates on threads when you post, this is an older one that hasn't been commented on in a while.
