TM L96 AWS Spring

I recently traded one of my G&G M14 DMRs for one of these little beauties. After 8 years of airsoft, I finally own my first bolt action!

Anyway, after skimming the internet for several hours, and realizing that "TM" "L96" and "AWS" are rejected by most forum search engines, I had to get a little creative looking for information about the gun. I've found most of what I've needed, the only last bit of info that I need is what springs will fit in the gun, and if anyone has used anything that isn't the PDI specific springs. The stock one is about 145mm long, and is extremely short in comparison to the other basrs that I've worked with. The advertised length of the PDI AWS specific springs is 210mm, which is about right after measuring the room that the spring has in the cylinder.

tl;dr: anyone have any experience putting a spring heavier than an M140 in a TM L96 AWS?

Yup.








Suppose you want me to tell you where to get one :-D



Look up Mark Man Craft, I bought an upgrade kit from him and it was a great piece of kit. Came with trigger, piston, and spring....pushed the rifle to 500 fps on the nuts.

I think I'm the third or forth owner of the rifle actually. One of the previous owners put a Laylax piston in it, and in doing so scratched the piston head to crap. Nice deep gashes in the brass, some on the feeding nozzle itself. How he managed to damage it this much is beyond me, but it doesn't seal the best with the bucking because of it.

And the cylinder looks like someone tried to put a screw that was too long into the body and kept going into the cylinder. It's only got that one spot, but it does rub a bit inside the body. The damage isn't so much that it's bent the cylinder, but it is enough that it prevents smooth sliding in the body.

I've picked up one of these to replace the cylinder and cylinder head. We'll see how it fits, seemed to be the cheapest, best option from what I could find.

The trigger appears to be a standard VSR trigger system, unless it's something special like the sears are just a little off spec, I plan on picking up some SHS replacement sears soon and running them until they fail or the trigger box cracks. It should last me long enough to talk myself into dropping $200 on the laylax zero trigger. The stock sears seem a little weak, but the box seems to be made of some decent metal.

The cylinder head is going to need to be a special build, as this is what holds on to the feed finger.

Though from what I remember the piston and the spring are specific to the TM L96.

The trigger system is able to use a VSR 1st sear, the 2nd is a different size and wont fit.

Right, I noticed the fancy feeding system. If worse comes to worse, I do know that PDI makes a beveled cylinder head with the proper cuts on the nozzle for the feeding finger. But I don't expect that to be a real problem.

Hmmmm, alright, I might still try picking up a few different springs to see how well they fit, or if they fit. From what I've been reading, I should be able to cut them down a little if they are too long without sacrificing much fps. Seems to be a little different from AEGs there. I guess the spring length and size make a rather large difference when compared to your AEG spring.

1st sear, got it. Looked around a bit, is the 1st sear the 90degree one, that contacts the piston, or the long flat one. Either way, I think I might just press my luck and see how long I can get the stock sears to last before getting the laylax trigger.

The 1st sear is the finger that holds back the piston, the second sear is the long flat one.

The springs are propriety to the TM L96. They are a little thinner and I believe a different length as well. I did try a few different springs when I had the rifle, and wasn't able to get any of them to fit. And no I can't remember what springs were used, they were what I had on hand before I sold them and the rifle.

A normal VSR zero trigger wont fit on the rifle either... you need a TM L96 specific zero trigger.

Yeah, Airsoftatlanta has them, but $230 is still a heck of a lot to drop on a part, lol. I could buy a gun for that, which is exactly what I plan on doing to get the part, selling one of my guns!

lol, I snapped a few yesterday, but somehow all but one came out blury...
Nice, I had the black version, and loved it. I kept it stock, and it too was well used. My only dislike, which holds true with all L96 variants, is the weight... you get used to it though.

Heavy guns aren't a problem, but unbalanced guns are. I'm thinking about putting some weights in the stock to help balance it out a bit. I might just try finding some dense epoxy/filler and filling in the stock a bit more. It used to creak a little, but I fixed that, it still has a sort of disproportionate, plastic feel to it. If I could fill it in a little, perhaps I could make it feel a little more solid.

Just an update. I got the Raven PDI cylinder set, the cylinder head is beveled, for those that might need to know in the future. However, the little O-ring that PDI likes to put on the back of their cylinder heads came loose, and the edge it was protecting is very sharp, and did a number to the o-ring and pad on the piston. I sanded it down and cut a piece of sorbo to replace it.

The PDI M140 spring was just a tad too long for the cylinder, even though it was made for this gun, I had to cut a few coils off. Once installed, I found that it was almost impossible to return the bolt back forward. Even with everything greased up, the inside of the cylinder and the plastic washers on the piston, there was just too much friction. If I had to guess, it's because of the angle that the sears engage the piston, they end up adding vertical pressure, onto the cylinder itself. My guess is that it was just enough to cause too much friction for the gun.

I thought it a little odd, because I recently upgraded an L96 with a much more powerful spring, and a similar angled sear/piston combo, and have no troubles pushing the bolt back forward. Is there something I'm missing, or will I just have to wait until I have the funds for a new trigger to be able to use the M140?

Could you please clarify which piston is difficult to push back forward and what rifle it's in?

I got a little confused with the mention of more than one piston and rifle :nuts:
