Hot Pink... You know, I could Pink Cerakote the receiver, White Cerakote the stock, then put rainbows, butter flies, and rinestones on the stock... That might get me kicked off the forum :mrgreen:

Here's a thought, what about painting the receiver Matt black and painting the stock white and putting a star wars imperial logo at the back of the stock? Kinda like a Imperial blaster!

Loosing the iron sight is the only major draw back. Having said that I have tried to use the stock iron sights and it's pretty damn awkward especially since you're using a chin weld and the sight picture is pretty awkward. That's why a quality optic is important for the PS90 in my personal opinion.

Progress at last! Ok, so I had a chance to get to my mill today and got to it. I milled out the receiver to take the Trijcon RMR base, then I had to shorten the base about 0.2". When I received the RMR Base it was almost 0.5" thick!!! The beauty of this set up is since I drilled the holes for a short Magpul Picatinny Rail I can always go back to using one if I decide to later down the road.

I really had to be careful in centering the RMR Base since this receiver is not exact. I found that the left side of the base was cut shallower then the right side of the base. The receiver base was squared to the vise/mill before I did any cutting as it seemed to be the most square part of the receiver.





The RMR Base was about 1/2" thick so I had to shorten down to just over 1/4" which took some time. It's also made of steel so I made sure I took my time and wasn't sure how fast I should go so I decided to take it easy. It's also pretty heavy for it's size and a bit pricey for $80!





I used the same MLok hardware screws to keep is simple since the receiver is already threaded for them. Since I shortened the RMR Base I found that the mounting screws for the sight is a tad long for the shortened base, so I'll have to get busy with a dremel and shorten the screws a bit.







Seems to fit like a glove! The Sight is at the perfect height for me and I'm very happy with the results!
Now it's time for final touches and coating! I'm thinking Flat black and painting the stock Storm Trooper White with the Star Wars Empire Logo by the butt stock. I've always wanted a good old Blaster. Ohhhh I also have to work on fabricating my Flashlight mount!

Well here she is, and almost, almost done. There's been a couple issues with the JB Weld and the Cerakote process but it will be fixed in a jiffy. I put it together in a quick fashion and took some quick pics. I'll be posting better pics after all the work is fixed and done but for the most part it's looking good. I'll do a write up in the near future.






I was hoping the receiver would come out a bit better but this is my first time and it's a learning experience.

So I took the time to take some good pics of my PS90 Space Blaster. I'm overall happy with the results but there are some issues I'll have to address.




I've never used JB weld for work like this and there didn't seem to be much out there as far as other people's past experience with it. Hopefully This will help someone down the line. I filled the void with JB weld and raised the level about 1/16" above the top of the receiver. When it cured it ended up looking like swiss cheese after taking a sanding block to it. I then applied a thin layer of JB weld to the top of the receiver and sanded it down after it cured rendering a nice uniform flat and flawless surface. Well after the Cerakoting process I'm assuming when the receiver was sand blasted, that layer I applied came right off. I will attempt again the fix this with JB weld and using Air Cure Cerakote and hope that it will be durable enough for use.

Maybe other epoxies like Almuhide might be a better choice. Also after sanding down the receiver, some areas were really rough from the casting mold. After sanding it down there were some very very small pin holes that I thought would be fine. Apparently the Cerakoting process amplfies the pin holes and creates large craters or craters after the coating is cured. I'll have to find another way to fix this through research.

Anyone know why the original is so high over the bore? Is it only because of cheek weld?
I can only assume that when they discontinued the original PS90 red dot (which was placed at the appropriate height). FN probably just said throw a rail on top of the receiver which would cost less than changing their PS90 molding casts and tooling.

But maybe someone else has a better answer.

They were still offering the U.K. Ringsight and the “Standard” receiver at the same time.

As an example, the Tri Rail is still available in the P90.
I wonder why they discontinued the PS90 Tri Rail version. Maybe they felt that it was more dangerous to society?

Looks great!!! I‘ve been thinks of doing the same thing to mine. I may try to get another upper to do it with. My only advice or question is why not use the job weld putty? I feel like it wouldn’t have bubbles in it?
