This! I really liked my Ares AW, but having to remove the scope to adjust the hop-up is counter productive.

You can always use taller scope rings to help mitigate this if your gun has an adjustable cheek riser. Then you might be able to reach the hop-up with the short end of an allen key, but still not great.

Internally from your pictures, it looks just like he inside of my AW, except a spring system. For spring I'll stick with Tokyo Marui, I'm a little disappointed to be honest.

Update:

So the piston is complete crap. The rifle has started slam firing.....
This after about 4 mags maybe....

I have done a lot of mods to try get it to work but what ever I do it lasts a few shots the slam fires again. The Plastic that the piston is made from is very soft and deforms quickly under stress.

No other option but to replace the piston with an after market metal one.

The piston is 104mm long.

I will probably order this piston in the next few days.

Not sure of your buget but i have one in my vsr and would suggest this

Also depending on what type of metal the stock sear is made out of the piston sear will wear quickly with the stainless piston so

One of theese will be needed soon. If it fits.
Or beter yet

I have the deepfire stainless ones but they dont have stock maybe someone else does tho.
The slam fire is a common vsr issue on stock pistons and sears.

[Arktic]

Those sear sets wont work in the trigger box. The first sear is a different design.

Ill upload pics of the sear soon.

I might get a sear laser cut from steel if possible. Its quite small and very a very simple design.

[Hectic]

Cool. Ya i wasnt sure of fitment that why i said.if it fits.
Check if its magnetic u may be lucky and find it is alrdy steel, tho i doubt it. Also if the price is right get bunch made im sure u can sell em easy enough.

[Arktic]

Its not steel but it is decent at least. It should do fine with an aftermarket piston. But I will try get them made up any way.

Ok here is a comparison of the MS 700 parts next to JG BAR 10 parts for reference.

Trigger Box

























I havent opened up the trigger box yet to get the sear out as I want to be sure I know how it goes back together before I do that.

Cylinder Comparison.















The piston of the MS 700 is 104mm long. The bar 10 piston is every so slightly wider in diameter than the ARES one. It still works in the rifle but it quite tight.

The piston of the MS 700 is made of extremely soft plastic and has started to slam fire after less than 4 magazines. Replacing the piston is a must with this rifle as using it in stock form clearly doesnt last very long.

[SuperHog]

I doubt the piston is causing the slam fire. My JG and TM also have soft plastic but I never got slam fire from that. Check your sear for slop. That can cause premature release when you cock.

[Arktic]

Slop?

I changed out the piston for the JG one in the pics and it doesn't slam fire any more.

[Hectic]

I have to dissagree my tsd sd700 started to slam fire quickly as well. If u would rotate the piston it would work for a while then slam fire again if u feel around the lip of the piston u could feel flat spots on it causing it to slip off the sear. Changing the piston to the pss one fixed the issue for a while till the pot metao sear wore down then i went stainless sear fo match the stainless piston lip. Been runin 512fps (pss sp150 spring) for a few years. Probably 1000 rounds or mors with no issue at all. Also using teflon coated cylender stock cylender head and spring guide pss10 airseal chamber custom nub stock rubber
Arktic did u try using the whole bolt set up from the vsr to see how it fits?

[Hectic]

By slop he means movement up down and side to side. But ur correct it is the wearing out of the soft plastic lip on the piston causing the slam fire. Jg and tm piston are a lil stronger then the one in my tsd was probably same deal with yours. Also tm spring is soft it would last a long ass time on the stock spring. Sub 300fps the jg one was 400 ish i think maybe 450 like the tsd

[seabass]

Awsome info dude. Have you tried swapping out random parts from the jg to the ares? Id love to know what is and isn't compatible.

[SuperHog]

Good to hear the JG piston works. You said it is a tight fit. Did you check the velocity for fps loss?

1+ on seabass request. Try testing the JG parts in the Ares. Spring guide, spring, cylinder and nozzle, sear group, trigger and hop up unit.

This! I did that several times before I gave up. I rotated the piston fired of 3 or 4 round then slam fire, rotated the piston same thing then slam fire. The JG Piston is a much harder plastic and seems to be doing fine. Im off to a game today so Im just hoping it lasts the day...

I didnt try using the whole bolt setup. I should try that. Maybe even replacing out the whole bolt with an upgrade kit could be an option as well.

As for slop. I didnt notice any left and right, its fairly solid. Theres no up and down or forward and back once it touches the trigger.

[Hectic]

Ya thats what im wondering if the whole cylender and whatnot will drop right in so i can just swap it out of my vsr. Two upgraded bolt actions and all i gotta buy is an inner barel for one lol.
Now we need someone to grab a. 338 to see what if anything is different from the 700
I may just get one im just iffy on importing stuff hopin a loce retailer will get em.
