M200 Intervention - Help Please - Inner Barrel specs

[White Wolf]

Hello,

Currently the owner of a fully upgraded VSR - 10 so I know a bit about mods and upgrades but I'm still learning and need some help on this one.

I just bought the Beta Project Cheytac M200 Intervention - spring powered.

1. Spring:
I am going to get a higher powered spring for it - M140 or so probably - do you guys know a good place to buy them from? I saw some on Toronto airsoft site but hard to tell if they are the right springs i will need or not... thanks.

2. Inner Barrel
I'm getting a custom made 800mm, 6.01ID, ported and crowned tightbore.
A guy named Eddy from the Philippians custom makes some really nice tightbores. However as he has never made this one before he wants to know:
- Is the Hop up cut for VSR or AEG standard?
- How about the Muzzle cut , standard OD or BULL barrel straight?
- Standard Muzzle cut is AEG diamter that is 15mm at the muzzle of the barrel.

Could you guys help me out with this one? I tried searching around online but no real luck... only thing i found out is that:
- the length is 800mm
- barrel type is an AEG type...

But I'm not sure on the authenticity of this etc...
Does anyone on our forums own one of these rifles?

Any help or references would be much appreciated,
Thanks!

As in anything custom made, you should remove the stock inner barrel and send it to him directly.

Also, 800mm is completely useless.

That's a given, as I stated - I don't have the rifle yet, its on its way - I was just asking around and seeing if anyone knew anything or owned one before while I was waiting.

Also dude, I know 800mm is ridiculously long and impractical - this isn't my first rodeo. However being that that is the length of barrel of the stock tight bore - I really don't see how you would get around it. If you have any suggestions I'm open to them.
However keep in mind that if you got with a shorter barrel it won't fill the entire length of the outer barrel and you can say bye bye to your accuracy after that, if the bb even gets out without hitting the sides of the inner barrel.
I may be talking out of my ass, I'm not even close to a pro yet - but again I don't see how it would work otherwise.

Willing to learn from the best.

Thanks for the reply,

I'm not the best or the be all/end all of anything. Actually...Kos-Mos would have reams of experience to pull from.

Maybe it'd be best if you got your hands on it and saw what's what in it. Is the inner barrel length really 800mm...are there barrel spacers already...etc...?

I was working on a SOCOM M82 (big barret) and it's a ridiculously long setup. In it's case it came stock from the factory with a typically long AEG barrel in it...sort of M16/AK type length I think. Absolutely...it was way short of the outer barrel length and it was basically resting on the inner bottom of the outer barrel.

It was a while ago, but IIRC what we did was order a custom EDGI barrel and I machined a barrel spacer (brass slug with 2 orings on it).

Did it need the super long inner? Nope...actually made it so no compression system combo would shoot reliably through it. I'm in the midst of putting a HPA gas system into it (since it'll blast enough air down the barrel for sure). I would have stuck to a 500-550 and a bore up kit.

So the long and short of it is...I'd suggest you actually get it first...check it out and narrow down on what you'll want to mod vs. leave well enough alone.

Have fun...the rifle sure looks cool. The nut-kicker of these big guns for me is that when you let a round go it's a complete let down since at most you have the same AEG V2 mechbox shot or a super quiet vsr10/L96 type sound. Some bolt guns seem to suit it...such as a suppressed m700/m24/m40 or a WA2000...but I was disappointed in the M82. It's big in size and relatively it's piddly in sound/range/power...but for something that you basically need a 16yr old sherpa to lug it around for you...to have it turn out to be just the same as any other AEG/bolt gun out there is sad.

Thanks for the great reply man!

Yea I'll definitely have to get a hold of it first and send Ed the inner barrel and maybe even the cylinder so that he has something to work off of. If I do end up going that route of course.
I figured out the spring too - it takes any regular sniper spring - like one you'd put in a VSR or w/e.

My real worry is the Hop up and how good it is and compatible or not.

For sure I agree with you about the points on it being big, long and heavy - I know for sure I'll be using my VSR way more then the M200 - but its just bad ass looking and it would be nice for certain games and terrain - like if I had to defend a bunker or a tower or something. Definitely wouldn't wanna be lugging it around the woods lol!
I also wanted it for the collection aspect, learning aspect and just the sheer fun of upgrading it.

Thanks again - I'll keep y'all posted XD.

I have the ARES m200 and I had the barrel out. It is an 800mm aeg type barrel. As such it uses an aeg type hopup bucking.

I am not sure about the beta project model.

How much will the barrel cost to get to Canada?

[Kos-Mos]

I would use a 500mm tightbore, add a set screw on a delrin barrel spacer and fix it at the tip of the inner.

Then make some rings from thick foam and winter boots soles (best material by far) and fit the rest of the space with them (alternating foam and soles, with random different hole diameter).

You would effectively have a very nice looking BA rifle and EXTREMELY quiet one.

Also possibly short-stroke the cylinder a bit if it is indeed designed to work with 800mm barrel (I doubt it... it uses VSR parts and a stock VSR cylinder can only go up to 550mmm past that you need a bore-up receiver and cylinder kit)

Those are some Awesome replies guys - thanks so much!

As per getting the barrel to Canada - I gave Ed my address when I was inquiring about a 445mm, 6.01ID Bull barrel ported and crownd for my VSR - and he qouted me: $75 for the barrel and $55 shipping
Which really isn't that bad considering the quality of what your getting.

Re Kos-Mos,
If I went the route you just described - and after reading it I most certainly want to go that route.
For the 500mm tightbore, it would be 6.01ID Yes?
- but would it be standard OD or BULL barrel straight?
- and would you still get it ported and crowned? Cuz it will be all the way inside of the outer barrel still so I'm guessing that would mean that you wouldn't port and crown it?? =/ I really don't know.

Also Once I get it all - would you be willing to help me do that custom barrel mod you described? I'm very handy - all you'd have to do is walk me through it.

It would be much appreciated!

Thanks again,
- Wolf

Crown yes, port not needed.

I would go with the bull version, but you will also need barrel spacers. I rarely buy mine, usually using a layer of double sided tape and some electric tape over it (the double tape gives the little squish to stabilize yet not jam the barrel). It's easier to perfectly match the inner to the outer that way.

For the foam pieces, all you really need is a gauge to consistently make the rings. I use some insulation foam tube for the foam part and winter add-in soles for the rest.
Best I found is to make sure the insulation tube fits inside your outer. You might have to remove a strip on the length to let it fit. Also make sure that when in there, the hole is at least 12mm (you need some space around the BB). When that is done, rough cut some rings out of it of different thickness (from 3 to 8mm). Then you have to make the rings out of the soles... that is a bit tricky. I found some washers that fitted just perfect inside my barrel (not loose, but not jammed... I got lucky). You can also look for bottles or anything round to make the rings. Mark and cut. For the middle, you want the hole to be LARGER than the one in your foam spacers. That is to let air (and sound) be trapped between the foam layers and not follow the BB.

You need just enough to fill the gap between the tip of your inner barrel and the outer barrel cap. When you have enough, stack them alternating foam/sole. Done.

Awesome, thanks so much Kos-Mos!

This is gunna be a reallllllyyyy fun project and a wicked rifle if I do it right XD.

I'll post up how it goes when I start the work on it in October.

I have M200 Beta Project, but I live in Vietnam, I can't custome inner barrel, I want upgrade inner 800mm 6,01; too. But, it's impossible!
