Outfitting a PS90 - Page 1

Posted: 7/23/2016 7:27:59 PM EDT

I bought one of these just barely. I have a bunch of plinking ammo inbound.

Where is the best place to buy mags?

What are the must have upgrades/accesories?

Thanks

I don't own a PS90 but my default response to these sort of questions is more ammo.

Hopefully you bought SS197 for plinking, as there have been cases of AE getting setback in PS90s.

Not sure on the best place to buy mags, but only use FN mags. Non FN mags are prone to cracking etc with just normal use. Not worth the hassle and wasted money. ManKave rollers are much better than the FN ones. They also make loading a bit easier.

TROS makes a low profile optic mount. I have an AMP engineering trigger in mine. Better than stock.

Just to emphasize what everyone else has said....
Use FNH magazines, 50's if you can find them at a good price, 30's with the web on the follower cut out and epoxied back together.
Get a nice red-dot sight and mount. If finances allow, get a mount designed to accept the sight without needing Picatinny rails, the extra 1/4 inch lower helps.
If you have a Gen-1 or Gen-2 trigger pack (do research) don't send your PS90 back to FNH for repair or you're likely to get back a Gen-4 trigger pack in return.

Midway has FN mags for $25 ea, if I remember right.

I bought 5K rounds of SS197SR. Is that the same as SS197? I would assume so.

I recommend the FN brass catcher & AMP trigger (it just feels nicer than the stock plastic trigger)

Yes, that's SS197.

IF you plan on using it for home defense, load it with FN SS198 (Green Tip)

Do NOT trust any ammo loaded by Fiocchi (FN SS197 (Blue Tip) & Federal American Eagle)

I don't waist my time with 30 round mags unless I can get them real cheap (usually not). I didn't need to epoxy follower, just stick the 2 sections back in the magazine, they ended up being 49 capacity.

I occasionally run a sparrow on my PS90 SBR but will use any of my compatible cans if the sparrow is on my 5.7

Maybe not the sexiest but I still feel the PS90 SBR is the best option for personal defense, 50 rounds, reliable, fast round in a small light package.

Ive been using the AR57 mags from cdnn $10 and they work great.
Got the ebay brass catcher. It works good.
Got a lower power sear spring and the trigger feels much better.
OE black ring sight works great also. Have a spare for sale.

Another mount option.

I'm running a Design Machine mount for my Primary Arms red dot. Makes a world of difference. Absolutely love it. Also have an Urban Sentry Hybrid sling set up. I'll highly recommend that, too. I have a spare T1 style DMachine mount laying around that I'd be willing to let go if you're interested in one.

+1 on the design machine mount. It was game changing.

Does anyone else make mounts beside design machine and tros?

is this still an on going problem? I read lots of stuff from 2012-2014, but nothing from 2015 on, or have people just learned not to use it?

I still use it for cheap practice (and malfunction drill) ammo. In fact I'm going to purchase an Elite Ammunition case gauge to check all SS197 before I load it.

I've personally experienced issues with SS197, I fired four rounds out of the same box through my PS90 that were so lightly loaded they wouldn't cycle the action and I even checked the bore to make sure a projectile wasn't lodged in the bore.

I can't seem to locate it but there was a fairly recent (last six months?) on SS197 showing new ammo with the shoulder of the cartridge pushed back.

That's why I will only use either Elite Ammunition or FN SS198 Ammunition for defense in my weapons.

Jay of Elite Ammunition posted a video of him tearing down Factory SS197 ammo, weighing each powder charge, and in one box he found more than a 10% variation in powder charges. In a cartridge with that high of pressure (50,040 psi) and that tiny of a capacity is a recipe for disaster.

Bigger issue for me with AE is short stroking.

There are others but those two are on "the cutting edge".

I'm running a TROS mount and an Aimpoint M3.

okay, TY.
My main concern is cheap plinking ammo, but I don't want to be putting my new rifle, or self at risk doing it.

ammo for HD is a whole new can of worms to try and find here in cannuck land
