Upgrading a TM VSR-10 - Additional help needed

[Crimzzen]

Hey everyone,
Before I get jumped on I've read Better than Bent's guide to upgrading the VSR-10s and in fact most of the upgrades I've selected are from his/her guide. I have a few questions though.

My field caps snipers at 450 FPS so I need to be below that. I'm aiming for around 430 FPS. BtB's guide recommends:

-Laylax PSS10 130 Spring
-Laylax Prometheus 6.03 mm Tightbore (430 mm)

There's a few things I've heard are also good to have, namely the following:

-Laylax PSS10 Zero Trigger (includes Orange High Pressure Piston)
-Laylax PSS10 Spring Guide
-Laylax PSS10 Teflon Cylinder
-Laylax PSS10 Air Seal Damper Cylinder Head

If I include the following pieces, will they bump me over the FPS I'm aiming for (430fps) or will they just increase my consistency/accuracy?

The improved seal from using a better piston, cylinder and cylinder head will probably increase your rifle's FPS. But it is all relative, if you compare it to the stock cylinder head, cylinder and piston, then yes FPS should increase, by how much, it is hard to say. These upgrades will also increase your rifle's consistency and accuracy. Springs are not very expensive, so if you are not certain, why not order a 110 or 120 spring along with the 130?

Also, if you care about accuracy, I would really recommend to change the hop-up rubber. While the TM hop up chamber itself is excellent, there are better rubbers on the market. A Firefly hard, Prometheus purple, PDI W hop or even a Reaps A+ would all be good choices.

Thanks,

Can I order these parts outside of Canada? Say in the USA or is it difficult like full blown airsoft guns?

All these parts are fine for import, the only restricted part on a VSR10 is the receiver, and if you have a real Tokyo Marui VSR, you don't need to upgrade that part.

Now to find a G-Spec in Canada :\

Porting the cylender to match the barrel length. Or adding a longer barrel will also increase the fps. I had a tsd sd700 with a 510mm inner. It shot 523fps. When i got my tm vsr 10 and swapped all the parts over and put a 455 inner it shoots 495.
The vsr10 cylender is optimal for a 500ish inner. The shorter the barrel the lower the fps. If you shrink the cylender volume by porting it the fps will go up. Or you can just put a longer barrel. I put the silencer adapter and a short compensator to get the 455mm inner to fit. With a short silencer i can go well over 500mm.

As a side note the gun is as follows.
Laylax piston (red)
Laylax teflon cylender
Stock cylender head
Deepfire sears (irrelevent but fyi you dont NEED to go zero trigger)
Laylax hop up unit/air seal chamber
Madbull 6.01 455mm inner.
Laylax 150 spring

Going to the cylender piston combo may net you 10-40 fps depending how good the stock one is working.
If the mating of the cylender head and hop up is good a new cylender head will do nothing.

Hope this helps. Good luck!

They are readily available from retailers on this forum. You simply need to get age verified to get one.

The gspec inner barrel is only 303mm of 330mm (cant recall) but you can hide a 500 in the silencer as far as i remmmber. With the upgrades i listed and a 130 spring should put you over 400fps

But that would completely defeat the purpose of the g-spec (a short rifle). He might as well buy a pro sniper version, it's cheaper too.

Good to know. I was verified by my local Airsoft liaison but I haven't seen anything happen yet.

Thats if yer planing to run the gspec without the silencer. With its long as an sd700 (uses 510mm inner)
With the gspec if you port the cylender you can achive the same fps as a 500mm inner with the short one by matching the cylender volume there will be no lost compression (ie the bb has left the barrel but the piston is still compressing air into an empty barrel)

But if you run the g-spec with the silencer, it means you want a silent rifle... extending the barrel inside the silencer will negate that. Also, the barrel will not be supported inside the silencer, so it could potentially reduce accuracy. Again, if you plan to use a longer inner barrel, get a pro sniper.

A vsr without the airbreak removed and a correctly matched barrel to cylender is alrdy silent. Even without an airbreak just a sorbo its almost silent. After 30 feet away you cant hear the report. Filling the voids in tue stock with foam does more to quiet the rifle then a silencer. And yes you can put a barrel spacer inside a silencer but that last 150 or so mm wont vibrate much to cause accuracy issues. Especially at only 400-450fps. At 550 600 without a sorbo pad the vibration is prety high but a sorbo fixes most of it and the two spacers in the outter bsrrel remove the rest. (i had a 600mm inner with a bore up reciver and cyl3nder on the sd700 with a silencer to hide it and only ran 2 home made (h9ckey tape) spacers with no accuracy loss. With a 180 spring it was just shy of 600 fps and shot 43's like a lazer.
It would seem that if the barrel is supported close to the hop up (like 1/3 of the way up) then at around 2/3 or 3/4 of the way up that the vibration is negated at the muzzle as it is disperssed by the spacers. And passing through the thread adapter will effectively provide a third spacer especially if you widen it out a bit and put a few wraps of tape on the barrel where it passes through the adapter.
Again not saying the gspec cant be as accurate as the pro sniper both with their propper barrel lengths just fps wont be as efficient if the cylender isnt ported to match the length.
I use a sorbo pad to slightly reduce cylender volume and run a 455mm inner and still have a 15-18fps loss as the cylender is still a tad too big.

Wow... that's one hard to follow block of text.

Having the silencer on does reduce the sound. Couple it with a sorbo pad, an air brake and a wood stock (which is much more effective at dampening sound than a foam filled plastic stock in my experience) and the gun is so silent that you can be firing from a well concealed place right next to a few enemies (not shooting them of course... MED and all) and they will not hear you.

Personally, I have 5 spacers in my G-Spec and 7 in my long barreled clone. The more the merrier. It does make a difference, up 'til the very end of the barrel. If you put 20cm of barrel inside the silencer, you have 20 cm out of your 50cm barrel that is not supported, that's 40% of the total length. It is sure to increase your spread by a few inches for long shots, which makes the difference between hitting and missing. As for putting a spacer in the silencer, I have serious doubts about that. The silencer is only threaded on to your barrel, there's probably some play, so it can't be very effective. And it is a lot of trouble. So why get the g-spec at all if you are going to do that? Stick to the pro-sniper. It is cheaper and much more effective for that purpose.

Sorry for the threat res. but does anyone know where I can pick up laylax parts in Canada? Zero triggers, cylinders, barrels, etc? I can't seem to find em in Canada anywhere... Would like to support Canadian stores.
