Ok guys... well I got all of my parts for my MK96.

Putting them together and I have a problem. I got the PDI cylinder set for her, didn't know needed a new spring. But that isn't the problem.

What I have is on the bolt handle itself. There are a few very VERY small parts and a few spring held pins. Is there anyone here that would be able to get a few pics of these and how they go in? I am looking for the parts that "engage and disengage" when you move the bolt handle up and down.

Thanks in advance guys.

Hey dude, check out my disassembly guide. I included some pics of the part on my bolt handle.

What you're looking at is essentially four pieces (not including washers/shims/etc.). The middle part of the bolt handle includes a ring and the handle itself, which slots over the projection on the outside/back end of the cylinder. Follow this by the blocky end piece, with the bolt handle to the right and in the "down" position, then screw this endpiece in with the end screw.

The last piece is the small metal nub attached to a tiny spring that slots into a hole in the "middle section" of the bolt handle. This allows the engage/disengage of the bolt that you were talking about. This is the *only* small part I know of in the assembly. You said there were a few, but it's really fairly simple once you figure it out.

The bolt handle assembly on the L96 is really annoying at first, before you've taken it apart a few times and used the rifle so that the parts don't stick together and resist disassembly and reassembly. Sanding and shimming would fix this, but usage achieves the same thing.

This is kind of vague because it's from memory, but I hope I described it well enough. If you want more pictures, I can take some

Hey don't worry about it.

Yeah I am thinking I am missing that little spring that goes inside of the handle itself. I did get her working, just didn't screw down the back screw so the bolt can still function.

I did get my plastonite cylinder set, APS Aero Charmber, and Zero trigger yesterday. Got her all together and am finding a few things that I am going to have to "tweak" to fit. No problem though.

Drilled a hole in the mag guide thingy to allow the mag to seat propperly. That and drill a very small hole for the adjuster to fit in there. That and what is that angle spring thing for? That looks like it applies way to much force to the arm itself.

Also get to tweak the rifle I got from Meteba. Trigger itself broke in shipping, so will jb weld that back together. Just have to figure out how to take the damn barrel off of the KJ M700... hmmm

In the PDI chamber, the spring provides extra tension on the hop up arms, although the main source is the large o-ring stretched over the middle of the chamber.

The long grub screws control the actual amount of hop, so don't worry about overhop. All this does is (theoretically) improve consistency. A lot of guys don't use the small spring, though, and are fine with just o-ring tension.

Oh I see. please specify ;) I also have that chamber (actually brand new, is on sale...but that's a different matter). The "v" spring takes the place of the o-ring, and I believe there's a similar adjustment spring with a grub screw

Yeah as of right now it isn't installed. Looked like it would put to much pressure on the bb. But will get her in there and try again I guess.

And yeah that little spring inside of the bolt handle itself. I think I lost that somewhere. So I think i am going to just file down the other pin in the blocky part so I can cycle the bolt smoothly.

Still tweaking though..

Ah, well that's the only thing keeping the hop up arm down. Have you shot it yet without that? Because I'm fairly certain you'll have major issues if you don't have it installed.

That should work fine, it just won't "lock" in the up or down positions so be aware of that. Good luck! :)

Yeah she shoots all over the place right now. Still haven't gotten around to putting that part in yet, but will tomorrow:d Yeah I know the bolt wont lock and I am kinda pissed at myself for loosing that little bastard.. but oh well she still works.

Been playing with my KJM700 I got from Meteba now, aside from the trigger shoe being broke she shoots great! Have my Edgi barrel in her and she is sweet. Just need to remember not to over tighten anything on the reg :( But other than that been a great time working on these two


Would you happen to know where to get some basic parts for the hop up in these rifles? As in the metal hop up part itself? Drilled it out thinking that my barrel wouldn't fit, only to find out that I was putting it in backwords. Of course that was all after I had already drilled it out. If needed can get the 2roy chamber. But the stock one would be cheaper
Could just get a boneyard one for $75 though and have another stock to boot

Evike has replacement parts for the KJ hopup unit. Along with other small parts. The little bag of parts has a hop-up nubbing in it ifyou are looking for one. Its clear polycarb and very tiny.

If you need some help, pm me and maybe we can go over this on the phone. Just tring to help.

Oh yeah that part is in there... I just had the chamber, that holds the rubber, backwards. So when I tired to put the barrel in it, I couldn't get it closed. So instead of flipping it around.... I drilled it out to fit the barrel. It was a great fit... but that wasn't the way that it went into the rifle


I have another part on order so no problem there

This hop-up fiasco was on the KJW rifle? Because drilling out the nozzle end of the PDI unit would ruin your airseal. Well...not completely, but you'd have no o-ring to "lock" the nozzle and a fair amount of leakage because the only thing causing seal would be the bucking itself.

Do you need replacement parts for the PDI chamber? I can send you everything except the actual shell. I bought a bunch of replacement kits back in the day. For instance, got about 6 of that tension o-ring. :)

LOL ... yeah the mess up was on the KJW rifle.... I know now.

Yeah the chamber I have for the MK96 is working really great. Haven't even put the adjustment screw through the top of the barrel. She is shooting great for just having the "stock" ammount of pressure on her.

Then again I still have the stock spring in her.... More of a CQB/Fast Recon rifle.

Actually by the looks of it they only have the replacement chamber for the takedown version, not the regular version :(
Dunno if there is a good source for non-takedown.

Yup that is the one that I have now.

The only difference between that and the original is that the "stem" is a little taller in the stock. But this one works just as well

I knew the stem was taller in the stock that's why I wondered if it would work.
Good to know! And here I was going to shell out for a 2roy to get a one piece chamber...silly me.
