Cyma m40a3!!!

threshold · Nov 10, 2016

Just stumled on this rifle while checking some stuff on taiwangun: CM.700 - Olive Drab [CM] - TaiwanGun.com

What do you think which system is it? Kinda looks nice and it comes with 500 fps stock. :yup:

BuMS · Nov 10, 2016

I think it's brand new, and I'm ordering one.
But they don't have spare magazines for it yet.

Dimitri MdP · Nov 11, 2016

Looks like a decent VSR-ish (?) gun on a M40A3 stock, at an awesome price.

Really hoping for a true VSR clone internals,that would make it one of the best guns around.

BuMS · Nov 11, 2016

From the look of the magazine, maybe L96 based?
I'm just hoping for a 90 degree trigger system.

kazuchan · Nov 11, 2016

From I see the mag, I think it had same design like S&T. But just hope it will have something better xD

coyotekev78 · May 13, 2023

Is that what is in the gun stock or possible upgrades for it?

threshold · Nov 11, 2016

I'd really like to see someone opening that thing and doing review on it, considering it comes stock with 500 fps and if it has half decent trigger , one could leave power and trigger upgrades for last

Mental96 · Nov 11, 2016

Oh my...And I was on the hunt for a new BASR.

Now I really hope for this to be full VSR compatible but I fear that its not...

BuMS · Nov 23, 2016

Just got it, and tried it.
It's not VSR compatible, as far as I can tell.
I've yet to take apart the hopup unit, cylinder and trigger box.
I'll take a look at the piston tomorrow, and maybe the rest.

But it's a 90 degree trigger system, metal trigger box, steel(Magnetic) spring guide stopper and steel(Magnetic) piston sear.

Edit: The piston and spring guide(Not the stopper) are the standard yellow/white plastic.

It's winter... And it was too dark to tell how the bb's flew...
I could hit a 4" pole about 80-90 feet away, by using the rail to aim(Didn't have a scope at hand).
But I couldn't see the bb, so it was only by sound.

I measured it at about 2.4-2.5J using 0.28g bb's(Converted to 518fps/157ms with 0.2g).

The body feels heavy and sturdy, compared to a VSR/BAR-10.

Freakman75 · Nov 23, 2016

Hello, I´m from spain, i have the new cyma and the s&t m40a3 and the are the same gun, no diferences. I have compare with my others snipers and I can say that the piston, piston head and cilinder are not compatible with the VSR.
PD: sorry about my bad english

BuMS · Nov 23, 2016

First batch:

The two body screws:

The bottom of the body, with a useless latch:

The top of the body, over the trigger guard and the useless latch...

The top of the magwall:

The bottom of the body with the useless latch closed...

The receiver assembled, and the spring guide stopper pulled out(Halfway):

The spring guide stopper hanging on to a magnet... So not potmetal. :tup:

The left side of the receiver:

The bolt/cylinder taken out:

The cylinder head:

More of the same:

All alone:

Here's the piston and spring guide:

A magnetic washer on the spring guide:

And the base is magnetic too:

A spring guide... How exciting!

And the front of the piston:

90 degrees of goodness:

Empty:

Pistons side by side... That's from airsoftpro, if you couldn't tell.

And look it fits :shot: That said, the piston is slimmer than a stock VSR piston:

And it holds air:

And now it doesn't:

The cylinder levitating magically:

So far so good.

Freakman75 · Nov 23, 2016

Great, where did you buy the airsoftpro piston and wich is the esact model?
regards

BuMS · Nov 23, 2016

Seeing as the airsoftpro piston will fit stock Well MB02, MB03, MB07, MB09, MB10 and MB11, you could try finding pistons, that fit them instead.

VietcongTroll · Nov 23, 2016

What type of SDIK would work (if any) and what aftermarket hopup unit it acceps is what matters the most to me.

BuMS · Nov 23, 2016

I don't any reason, why a vsr mancraft kit wouldn't work.
And more or less the same for the BOLT, you could fit the battery under the latch.

Mancraft · Nov 24, 2016

Guys! Please tell me 4 things:

Length, inner diameter of the cylinder (I believe, it's ~22mm, right?), length, diameter of the nozzle

.

VietcongTroll · Nov 24, 2016

If this means that you think you already have SDIKs compatible with it or that you will make them I'll gladly buy and send the measurements and even the entire rifle if necessary.:lmao:

Mancraft · Nov 25, 2016

Thank you BuMS

.

248mm inside? like marked on that photo? If so, it will be the longest cylinder ever I think

L96 one have ~232mm. Can you put photo with measurment here? Do You maybe have caliper to measure it bit more precision?

VietcongTroll, we will be able to make them

. We will be also able to put upgrade parts (cylinder head and brass pin) for VSR to upgrade to that CM700 standard

.

BuMS · Nov 26, 2016

Sorry... I got distracted by life...

The hopup is a very small clone of the PDI chamber(For VSR), with two arms and all.
I don't think other chambers will fit.
And it uses AEG barrels.

I'll try making a 3D printed hopup to replace it(If I can get off my lazy a**).

I got the pictures, just got to edit them.

VietcongTroll · Nov 25, 2016

That's fantastic.

The lack of information about the hopup worries me tho

Mental96 · Nov 25, 2016

Yeah, please BumS post some pics of the chamber area and I you could compare it with to a vsr chamber.

BuMS · Nov 26, 2016

Here's some more.

The left side of the receiver is held on by a screw. And a grub screw for the right side.

Now the trigger:

And on the inside:

All the parts laid out:

And the sears can levitate:

These guys won't ever see my gun again:

Here's the magwell(And it's two screws), the small grub screw secured the outer barrel:

The grub screw that secures the hopup unit:

And a empty barrel:

Here's the whole barrel assembly:

The top of the hopup unit:

Two grub screws for the arms, a o-ring for tension and a wide round nub:

The two grub screws secures the barrel to the hopup unit, and the plastic piece aligns the barrel(In a quite clever way):

Side by side some VSR barrels:

And that's my SDiK inside the barrel.
My SDiK is not long enough, as moving part moves too far forward:

Scaling things up:

If installing the SDiK, the spring guide stopper pipe, has to be reinstalled:

Don't like how mancraft made this part, the tube kinks when inside the cylinder(Some sort of L shaped insert, would have been nice):

With the stopper pipe back in place:

Fits over the trigger too:

The line can be routed out through the latch(Now less useless), but it does get pinched slightly:

That's a airsoftpro cylinder(VSR) fitted with a small buffer. The buffer makes it protrude a bit(Into the hole where the spring guide stopper fits)
But the buffer is only about 1mm thick, and the protrusion is more then that:

The piston and cylinder head:

BuMS · Nov 26, 2016

The only parts I don't like, is the hopup unit, barrel choice and the nozzle diameter.

The nozzle diameter is a problem, as it makes poor contact to the bucking, risking leaks.

If I/we make a replacement hopup unit, these problems should be easy to fix.

It's late here(2 AM), so good night.

kazuchan · Nov 26, 2016

internals of this CYMA version so good ( except chamber ). Think about got one in future lol xD

VietcongTroll · Nov 26, 2016

As expected the hopup chamber is apparently 'propietary'. Such a shame.

Plazmaburn · Nov 26, 2016

That hopup unit looks like a PDI clone. Such a poor choice.

saboter · Nov 26, 2016

I ordered this 2 days ago planning to install my mancraft kit. The cylinder length is too long. Its like the agm L96 in which, when i isntalled the mancraft kit, it was leaking air because the brass hole was not far enough inside. ANy way to fix that? My thoughts is that we need a longer mancraft middle cylinder.

EchoBryan · Nov 27, 2016

I just have one question BumS, I'm a little confused about the trigger system and cylinder. If I want to do a full upgrade to this rifle (not with a SDiK, keeping it spring operated) what systems do I need to look for when upgrading if it's not vsr-10 compatible. (I.e- sear set, cylinder, piston, etc) thanks and sorry if you already answered this. Just need some clarification.

BuMS · Nov 27, 2016

Well, right now there's not much you can upgrade.

Things that can be upgraded(Parts that are available):
Piston
Spring guide
Inner barrel
Hopup bucking/rubber

But unless you run the rifle over, there's not much that needs replacing/upgrading.

The main part on a VSR you need to upgrade, is the trigger system and piston(If you plan on running a high power spring).
And for that, you'll either need new steel sears or a 90 degree system.
The 90 degree system is the preferred choice, as it lightens the bolt pull on heavy springs.
And this rifle already got one.
The sears is also steel, just as most(all) upgraded triggers.

This rifle is about 137 Euro(~145 USD)

A BAR-10 is about 105 Euro(~111 USD).
And then you need a trigger.
Airsoftpro trigger(Bundled with piston and spring guide) 80.60 Euro(~85.37 USD).
Or a Action Army(Bundled with piston) 170 Euro(~180 USD)

BAR-10 + AA Trigger = 275 Euro(~291 USD)
BAR-10 + AP Trigger = 185.6 Euro(~196 USD)

The BAR-10 got a better hopup system, but many people upgrade it to a
Action Army hopup unit anyway.
And then there's the barrel, which is one of the first thing people replaces.

@Asianwarchief The trigger pull is very light.

Asianwarchief · Nov 27, 2016

Oh wow the trigger looks like a pdi v trigger design. I wonder how well it performs.

EchoBryan · Nov 27, 2016

Alright! Thanks a bunch for the response. I've already bought the S&T PDI Custom M40A3 version of this, and since its identical I wasn't sure what parts are compatible. I'll definitely use this information to start gathering my parts list! If you have any more knowledge on this product or the one I'm buying please let me know! I'd love to learn as much as I can to make my sniper rifle a powerful gun on the field!

Mental96 · Nov 27, 2016

Hey BumS, Is there a chance that a VSR outer barrel could thread with the reciever?

BuMS · Nov 27, 2016

I just tried mounting my BAR-10 outer barrel, and it fits.
The problem is, now I can't mount the magwell. And the bolt's longer, so it won't fit.

Cyma m40a3!!!
