Psg1/msg90

[naminator]

I currently have a JG I believe G3 SG1 that I want to use as a DMR.

I want to turn it into an MSG90 but finding the conversion kit for that is like trying to find the shroud of Turin. I have contacted several retailers over seas about this part and all responded with it being out of stock. I haven't even seen any ridiculously over priced ones to buy.

I know the MSG90 kit is the easiest to find, but I have noticed the TM PSG1 Front End replacement part at a number of sites. If I where to buy this, how many other things would be needed to complete the front end and how hard would it be to frankenstein this together?

Any advice is appreciated.

well...the MSG90 has the long barrel and front handguard of the PSG1 but retains the full length 20 rd mag of the G3/SG1.

I used a G&G stock, a CA SG1 cheek riser, TM front end. 650 mm inner barrel and a custom outer barrel.
It ended up looking like this.



Expensive and hard to find the correct Zeis scope and mount. I also used the CA SG1 extended recoil pad. I alternated between the PSG1 grip (not correct fr MSG90) and the OD G3 grip (correct) The MSG 90 does not have any iron sights but I did not come up with a suitable solution to fill the hole remaining where the iron sights were. The authentic MSG90 flashider/muzzlebreak) is impossible to find so I just used a constant diameter outer barrel without a flash hider.

Internally this gun was built with a reinforced 8mm gearbox, all upgraded hi torque internals and fired 470 fps with 140 spring. I did block the selector with a small set screw to shoot semi only as in the MSG90.

Is there a non custom barrel that I could get? Since you have shown that the PSG1 handguard works I will get it, but is there any of the barrels out there? What can I do to get one of the custom barrels if it comes down to that?

The Zeis scope is pricey but meh, I want to make the best PSG1/MSG90 I can.

Thank you very much for your input so far. I was contemplating PMing you about that gun build.

Any non tapered barrel will work. I forget the actual length though...I no longer have my gun to measure. The G3 barrel is 2 parts as you know.....the threads end at the end of the handguard so you can just add a barrel extension and a muzzlebreak.......the total length should be 650mm (the length of the PSG1 inner barrel) but my outer barrel ended up being too long so I was going to make a shorter one but ended up selling the gun.....

Will either of these works?

(sorry for asking for a spoon feeding)

The PSG1 barrel looks like it will work...but there are no dimensions or lengths given. The other barrel is a stock length G3 barrel so it will be the same as what you have..

You can get a G3 SAS or MC51 barrel and add a longer barrel extension. Since it would end before the end of the hand guard, the joint would be hidden.

I think you can also install the PSG-1 hand guard directly or with very little modification. It extends a bit at the front unlike the G3-SG1 and very much like the MSG-90.
