Need tips for VSR Upgrade

Hi guys, I bought a Well MB03 a while back to see how sniping felt like.
I've enjoyed it and decided its about time to do some improvements to my rifle.
This is what I have planed to do:

1st upgrade fase:
Action Army Hopup Chamber: https://www.skirmshop.nl/en/action-a...p-chamber.html
Maple Leaf Autobot 60 (Summer): https://www.skirmshop.nl/en/autobot-...60-yellow.html
Maple Leaf Autobot 50 (Winter): https://www.skirmshop.nl/en/maple-le...ucking-50.html
Action Army 500mm 6.01 Inner Barrel: https://www.skirmshop.nl/en/500mm-60...or-vsr-10.html
Action Army GSPEC VSR10 Inner barrel Spacer set : https://www.skirmshop.nl/en/action-a...pacer-set.html

2nd upgrade fase (most likely unecessary):
Action Army Twisted Cylinder: https://www.skirmshop.nl/en/twisted-...lver-grey.html
Action Army VSR10 S-Trigger set: https://www.skirmshop.nl/en/action-a...igger-set.html
Action Army receiver: https://www.skirmshop.nl/en/cnc-vsr1...ver-black.html
Maple Leaf Bolt Handle Endcap: https://www.skirmshop.nl/en/rock-sol...or-vsr-10.html
Action Army Bolt handle: https://www.skirmshop.nl/en/action-a...le-type-a.html
Maple Leaf Rail: https://www.skirmshop.nl/en/maple-le...lue-model.html

I'll only proceed to the second upgrade fase a few months after the first upgrade fase is concluded (need to gather the € again).
My field limit is 1.3J
I'm using .36g but can swith up or down depending on recomendations.

I'm looking for opinions/recomendations on these upgrades.
The store in the links is not a must. I just chose it because it has all the components and saved me time search other sites
I dont understand yet how to set up the proper cylinder volume. I understand that is a very important step to optimize the spring energy. Hopefully I can get some tips on that too.

So your field limit is really low. You may get away without having to upgrade your trigger but you would need to change the inner barrel to get the efficiency and power you need. 300mm is way too short.
If you are going to use 0.36gm bb's then a 500mm x 6.01mm inner barrel would be your best bet (Action Army have an AEG barrel that is 470mm x 6.01mm that would do the job). This would make your rifle more efficient. (I take it you have a g-spec and so you will have to have the inner barrel go into the silencer. Th 500mm will take it right to the very end but not stick out. You will also need to drill out the end of the silencer for the inner barrel to fit through.)

The only thing in the second stage that may be needed is the trigger. But with such a low joule rating, I would look at a JJ VSR10 trigger. They are junk but they will handle up to about an M150 (about 2.2 joules). These are way cheaper.

Also, make your own barrel spacers.
Wrap 1 layer of Masking tape around the barrel with the sticky side facing outwards (This is so your barrel spacer is not permanently stuck on to your inner barrel). Then with the adhesive sides facing each other (So it is not sticky on the outside) wrap the Masking tape and around and around the inner barrel until it fits snugly into your outer barrel.
Do not use electrical tape as it stretches under tension and then it move by itself. Masking tape does not stretch.
It is normally advisable to have 2-3 spacers in your barrel.

Hi, I deduce you are from Portugal, so am I. From personal experience you don't need a trigger and you should focus on efficiently using the air, which in vsr platforms is low compared to other platforms. On 1.3J I found the best range and accuracy when using hpa snipers or SRS because of the high cilinder volume I guess.


You should focus on the barrel/Hop assembly before anything, after that if you are sticking with the vsr platform I would put an hpa kit on it.


For the hop rubber try a 50, 70 is out of the question and 60 in some days its too hard, maybe 50 in winter and 60 in summer, would be my sugestion.

VSR's are known to have a high cylinder volume. More than enough to fling a heavy bb. In fact, for many years, the VSR had the biggest cylinder. In recent years there have been some rifles made with bigger cylinders. The SRS for example. But the VSR does have more than enough to fling heavy bb's. Even up to 0.66gm.
A 0.36gm bb is perfectly matched with a 500mm inner barrel. So a long barrel.

You could go down the HPA route but the only advantage would be quietness (Disadvantage is hose and tank on your back). In saying this, at only 1.3 joules, you can make a VSR pretty much just as quiet as an HPA rifle (I wouldn't be surprized if you could make it even quieter than HPA. My current VSR10 that shoots 3.3 joules is as quiet as a Socom pistol. HPA is a little quieter than my VSR but with only 1.3 joules, I am sure it would be achievable)

I wouldn't really bother with HPA at that power level.
I own a shitty spring VSR-10 and an HPA VSR-10 (old style Wolverine BOLT) and I definitely prefer the HPA one, but if the springer weren't leaking tons of air, had a nicer trigger, had a nicer piston, and wasn't using a sketchy M175 spring, I'd probably like it.

My suggestion would be a G-spec style VSR-10 with the following parts
Maple Leaf Crazy Jet 350-500mm barrel
Action Army hop chamber
Maple Leaf Autobot or MR-hop bucking in 50-60
Stock piston
Stock spring guide
Stock trigger
Laylax spring
Spring spacers
Foam filled outer barrel and stock
Good suppressor
And a new cylinder when the stock one breaks.
You could probably get that stuff for less than $100, and you will be very close to HPA sound levels

I have almost reached my limit with sound on my rifle, at 1.39J it's just a click, a slight whoosh, and a whistle.
At 2.98J it's still quite quiet, but it's more noticable. Still better than my highly modified SSX23, which is rather quiet.

You should be able to achieve a very quiet rifle with spring power due to your power level, definitely more quiet than any MK23 you'll find.
I would suggest that you keep an eye on the "wat am bset gnu" thread on here, it should be extremely helpful for your purposes due to a similar power leve

I've updated the inner barrel from the first post.
Regarding the BB weight, I'm open to recomendations as I've said before. I'm using .36 because I read somewhere that they have the best speed/energy retention ratio for my 1.3J power limit.
If I wanted a heavyer bb, what would I need to change in my upgrades list?

It you were using heavier BBs with a spring as a power source, you would use a shorter barrel.
If you were using HPA and wanted to use heavier BBs, you would change nothing.

I would recommend anything from .36g-.48g for you, as long as you can hop the heavier ones.
A heavier BB will travel farther than a lighter one, so keep that in mind.

The 470mm inner barrel I suggested will allow you to use up to 0.4gm effectively.
At 1.3 joules though, I personally I would use 0.32gm. At the most 0.36gm.

Why the .32 or .36 and not a heavyer .4+?
Is it because of the velocity/energy retention ratio I mentioned before?

Chances are you will get more range with 0.32gm-0.36gm. The joules rate that you have is very low and so the backspin on the 0.4gm will not be fast enough to hold it in the air as long. But if you want you can always experiment but I am pretty sure the 0.32-0.36gm will be better.
kazuchan and SiliconeSword like this.
