yeah that's TMH's stock. He stated that happened after firing some of the EA ammo I had sent him. Mine has not had that happen, but mine pops the mag up on most EA's stuff except S4M and T6

They really needed to make the P90/PS90 a delayed blow back. Besides a stock fix I have messed with that but like other things I just run out of time in a day.

Re: PS90 Owners I Need Your HELP! (JB WELD epoxy)

How about renewing the forward edge of the reciever lock hole with JB WELD epoxy?

That stuff is actually more wear resistant than the the PS 90 polymer stock.

Crumbles after first shot tried that years ago.

Clip like the ones used on the old style magazine lips can't be made thick enough to not break, not enough clearance between stock and receiver.

I am testing a fix by just cutting the section out and replacing it with an aluminum insert. Securing it has been the issue.

Was looking at my ladies PS90 and realized something. Her Duracoat in that region is holding up against the punishment that section takes pretty well. It's not even removed the finish yet. If it ever does, I'll just hit it with another coating. Seems that by cleaning the poly stock with the Duracoat degreaser, it allowed the duracoat to bond pretty well. Makes for a pretty good extra layer of protection. I was leaving my PS90 black, but maybe I'll put a coating of midnight black on mine to give it a lil extra protection too.

Would it not be much simpler (and less costly) to increase the spring rate on the magazine catch?

Yes, Jay offers a tougher mag release spring.

Hello everyone.

I am new on this forum and i am looking for help.

I want to make for airsoft gas blowback version of P90 TR (made by manufacturer called WE) plastic sticker with FN marking. Your may see it on left side of body, it's saying: "Fabrique Nationale Herstal BELGIUM". Somehow WE didn't made it and airsoft version don't have markings at all. It's look fine overall, it's still P90, but this kind of small details make it more real and cool.

What i have got so far:

1. Exact marking text (Fabrique Nationale Herstal BELGIUM);
2. Size of niche on airsoft P90 TR for marking;
3. Exact font used for marking on P90\PS90;

I am looking for:

1. Scan (or high resolution photo) from top of a marking;
2. Size of niche on PS90 (just to compare airsoft P90 TR and PS90).

Scan is ideal for marking. It will give me exact coordinates of each letter and with with high resolution plus exact font i may do it clean and easy.
