TM PSG-1 Upgrading

12285 Views 20 Replies 6 Participants Last post by  inthetallgrass
I'm hoping to upgrade my TM PSG-1 over the next few months that has been sitting around for a while.

Have any of your guys ever upgraded one/had any experience with them?

I know of the Systema FTK kits, but I'm also wondering if the Guarder upgrades are any good? They make a lot of the internals, just no gearsets. One other thing to note, I have a spare set of stock gears/piston, and a Systema motor that needs a pinion gear. I'm not looking to get crazy FPS out of this, just some decent range and good accuracy.

Any opinions/experiences? I know this gun isn't owned by a lot of people, but I figured I'd have the best luck asking here.

Haha, I did PM him a while back about fitment of the PDI Chamber Block and the G&G Magnesium Receiver, but never got a reply. I'm pretty sure he's the best guy on this forum about the PSG-1.

However, I did do some searching on google. Not many people have this rifle, or upgraded it, but I did find something Wonko posted as a reply on ASF and it seemed like pretty good information:

"A PDI chamber block is an absolute must, otherwise the rifle will have a substantial amount of flex at the barrel/receiver joint. The G&G metal body is also a must if you can't stand creaky plastic rifles. The PSG1 is very creaky and moany with the plastic body.

PSG1 internals parts rare and expensive, one part that is an absolute must for high FPS upgrades is no longer made by any company. The anti reversal switch is a must for the way the gearbox works, the stock one is too soft of a metal to last in a high FPS build and will wear down. Once this happens you will have a next to impossible time finding a TGS Steel Latch to replace it.

The gearbox is a very complicated one to work on, if the gears in the box are out of timing by one single tooth the entire thing will not cycle correctly. If the gearbox is attempted to be cycled out of timing you risk breaking something inside of it.

They are very very expensive rifles to work on and quite honestly need just about everything replaced to truly be reliable.

Due to the scarcity of parts, you might want to contact Redwolf first if they can still do the power upgrades.

If you're after a fully loaded PSG-1. I've got one for sale. It doesn't fall in the price ranges of a normal player though, but it's worth the price."

After reading this, it does seem like the new PolarStar Fusion Engine would be the best/most reliable way to upgrade it, which is what he was doing to his not too long ago.

If anybody else has anything to throw into this, go ahead. I'd like as many opinions from people as possible.

Yes, it does seem that way...

If you can't wait for the P* GB, then yeah, you probably should have speaks with redwolf.

I seem to remember one other PSG-1 guru, I will have to find them...

Goooooooooooooo Google-Fu!
Well, gotta guy that I run with where I play with a fully upgraded PSG-1 that's willing to help me out. Should be ordering upgrades sometime soon in the near future.
Will do

So far, here's my upgrade list:

PDI Chamber Block
G&G Low Profile Scope Mount
Leapers 3-9x50mm Scope
Systema 400% FTK
7.4v 2200mAh 20C Lipo
Deans Connectors

May get a new barrel sometime, or just polish the stock one. Another future upgrade would be the G&G Magnesium Receiver, but won't likely be soon. I already have a Systema Bucking/SCS Spacer combo.
TM PSG-1 Bipod

Yes, but the PSG-1 takes a special scope that mounts different than a normal one. It's a Hensoldt replica, but it's not that great of a scope and has a lot of tunnel vision to it. I'd like to be able to mount a larger, nicer scope to it. Also, with the plastic body, the scope has a lot of flex, but I'm not sure if this mount will fix that or not.

HAHAHAHAHAHA! The person asking about the psg-1 was me.
If I were you I'd get a G3, heavily upgrade it and then get a conversion kit if ones available or mod the G3 body into a PSG-1 metal body. Do they sell small G3 mags though?
naw; then you don't have the v4 gearbox!!

Also that guy who you run with sounds like a real champ, you should buy him a cookie
Ha, been wondering if you were on here Skywalker! We need steel anti-reversal latches!

That'd be the point. You get to use all standard parts, rather than being limited to Systema FTKs and an ARL that is at this point fairly irreplaceable and NOT capable of withstanding such high spring powers for an extended period, especially when it has to hold the spring almost completely compressed (pre-cocking). Since Extreme-Fire and AWS MOSFETs have now made pre-cocking not only doable in standard V2s, but much more reliable than the purely mechanical V4 system, the only practical advantages the V4 offers is the split design if you find that helpful, and the increased cylinder volume.

We're going to try to get one machined by somebody. Skywalker's ARL is holding up fine so far on the 400% spring (largest made for PSG-1).

Split type and increased volume are quite helpful. And 'inthetallgrass' didn't suggest electronic pre cocking, thus that idea was somewhat lesser than a v4. Yeah, you could put all that work into building a custom psg1 that uses a v3 and pre cocks electronically, but its not worth the effort. I've been running the 400% for 4 months I play almost every weekend. Yes I don't deny the part is a weak link, but its easier to count on it than do such a custom build to produce the same thing with slightly more reliability.

What about a version 7 gearbox? They any good? Also is there no way of buying a version 4 and custom fitting it?
I don't think I understand what you are talking about... a PSG-1 comes with a v4. What gun are you talking about custom fitting a v4 into?

A OSG is a modified G3. Get one and custom make it yourself.
Then it wouldn't be a PSG-1. Of course in real life it is an accurized variant of a G3, but there are many differences in the rifle. You could get it pretty close, but it just wouldn't be the same. Also, the V4 gearbox is pretty nice; I just want to try to get a steel latch made since they are discontinued now.
