r/ps90

Just picked up a PS90 and this mount is too narrow for my RMR. Hoping to get some insight on what does fit or the best option for RMR mount

Need to send it off for the barrel cut.

Almost don’t want a can on it to keep it a short as possible.

Wondering if anyone is running a MS5.7 on a PS90, particularly the K version. I’m looking to get a CMMG plan b brake to mount it. Anybody got this setup?

Just about the perfect size for an SBR PS90 depending on length on muzzle device. I added the Vertex Laptop sleeve to create a kind of pouch so I could put Velcro accessory and mag holders on.

So I want to get the TiGER22 Ti for an SBR PS90, with an FRT. B&T website says conflicting things. One section says full auto for .22 lr only. Then another section says full auto for .22 and 5.7 as well. Anyone have experience with this?

is there another go to sbr ps90 can?

I ordered this thing on Amazon about 2 months ago. A bit of a late night drinking purchase! Anyway it arrived today. Little Day/Night LVPO. Advertised as 1-6x, more like 1-3 and a bit!
I have no idea what I bought it to go on, but it fits quite nicely on the side pic rail! Reviews look good and they are always on back order. It’ll probably end up on my 300 Blk Out Rossi brawler.

I got the CMMG plan B flash hider muzzle device. I’m just wondering what do you all think for 5.7 - full size or K polonium? The full size on my 12.5 AR is amazing. I think the full size on a 5.7 sbr might be overkill.

Making good progress, have 7 plates modeled so far, a few tweaks left but mostly complete.

The plan is to have a 2pc system, a “base” with low cost interchangeable “plates” for all red dot foot prints I can get my hands on, so you can try different optics without spending $80-100 on a new mount each time.
All will be machined aluminum, but I’m getting some good use out of my 3d printer.

We’ll see if there’s a market!

Install wasn't too bad. I had to watch the Dorin video slowly several times. Took about 20 minutes.

I greased the bolt and saw a post about running the charging handle 50 times, looking for wear on the bolt, and applying more grease to those spots. I did that a few times then took it out to the woods to try it out.

This video was my first mag. After some semi auto fire, I tried the FRT with like 35 rounds in the mag. The first burst was just getting used to it. The second burst finished the mag with no problems.

Unfortunately my phone battery died so I couldn't film more, but after this I mag dumped 2 50-round mags with no stoppage. May post some mag dumps later.

I decided to go the diy route for sbr just due to getting a free 10.4" barrel gifted but i cant seem to find the pin although it across for the prefilled hole. Am i supposed to go a bit lower from where i drilled? Or is it more of digging left and right? I dont care much for the barrel so i might just saw it off but if its not a lost cause yet then ill take some tips to preserve it.

My 3 sons surprised me this Father’s Day….big time. One of my grail guns, PS90 SBR. They had it all bought and paid for. Got my Form 4 submitted on Monday and brought her home today! Gotta love 2 days for Approval. Now the fun begins. The can is my Switchback 22 in short mode with a Griffin Armament QD set up. One of the few QD mounts for 22 cans.
