Man Kave rollers (must have, reliability improvement)
Man Kave Magazine Catch (billet aluminum vs factory plastic) Elite Ammunition QD sling mount K&M Aerospace Folding Charging Handle (by far the best choice in charging handle upgrades) TROS Low Profile scope mount for your choice of optics. Choose a self defense load... FN SS198 (inexpensive choice) Elite Ammunition T6B (choice for penetration) Elite Ammunition S4M (hottest load available) R&R Systems R37.X (solid copper expanding hollow point, it will go through a Level IIIA vest) |

Gonna wanna save an extra $200 plus the cost of a hacksaw, dowel rod, and TROSUSA barrel cut/thread.
Makes a kinda neat gun into a total badass gun. |

Eh, I've got some cans already. A SBR doesn't get me too excited (yet), so I'll pass for now.
I heard about the rollers & the charging handle in other threads. Keep 'em coming please. |

If you decide you want the TROS pic mount, I have one I will part with. I ended up using the Design Machine mount as the optic I have did not fit properly with the TROS. (Holosun HE507c for those wondering)

While I know I'll do a large charging handle knob, has anyone done the oversize mag release handle? Or is it too easily hit by mistake as on a 1911?
Thoughts on a sling? I would assume a one-point is the way to go? Bungee type? |

The Man Kave magazine release isn’t really “larger”, it’s just cut from billet aluminum and the serrated edges are “sharper”, hence making it easier to cycle. |

While certainly not speaking against Man Kave 'additions,' the gun will work just fine without them (assuming FN or AR57 mags).
I like the standard 16 in (well, not quite, but with the integral device) barrel quite well since I'm not trying to hide the gun in my pocket and you get more velocity with the longer barrel (and speed kills). For HD purposes, shorter will probability not be a great advantage (we can always make up scenarios where it does, of course). And there can be other advantages to short, of course... If you are going to use it as a home defense tool, make sure that you choose an optic that will be dimmable enough for night-time use. Currently, I am using a Vortex Razor RD on one and a Burris Fastfire III on another... Forrest |

Forrest There is a major drawback to the standard length FN PS90, being that it’s blowback the longer dwell time can cause issues with hotter ammunition. The springs and bolt carrier weight were developed around the 10.4” P90 barrel. Unfortunately FN didn’t make ANY calibration changes when they introduced the PS90 with a 16” barrel, it has the same carrier weight and the same action springs. There are numerous reports of magazines popping up when using certain loads in the PS90 that doesn’t happen in the P90. |

I admit that I shoot the FN (Fiocchi) SS-197 almost exclusively, and have never shot SS190 (or 'commercial equivalents.' ). I might be happy to agree with you if I did...  . Of course, most will probably just shoot the SS197 (or SS195) and will be happy with the stock rifle...Having said that, I have nothing negative to say about some of the aftermarket 'iupgrades' (I'm thinking especially of Man Cave stuff here). Especially If I was attempting to use a sound suppressor on the gun, I would probably be singing a slightly different tune... Forrest |

Absolutely to each their own. A PS90 with 16” barrel reminds me of the social distancing guy picture with pool noodles taped to his hat. He’s not wrong, but...
If you have 16” of barrel real estate and accompanying OAL, there are better options out there. I absolutely love this platform SBR’d with 50rds of SS198LF aboard. In a 16” barrel I start thinking AUG, Tavor, et al for comparable $ and a significant energy boost. |

EFFEN90 receiver. Much lower optic rails, and side rails are easily removed if not needed. The sticker you get with it is AWESOME, it's almost worth it for that. I got every part they make for the rifle....
ManKave rollers help with feeding on all of my 50s. Elite Ammunition S4UR or S4M ammo is the tits. I measured just over 3100fps on my SBR. 5.56 can will work fine, I use my Sandman K Elite Amunitiin sling attachment |

I didn’t even take mine out of the house with the 16” barrel with shroud.
That’s right it’s not just a 16” barrel. They added a shroud for the overall length requirement. Very lame SBR is a must if not I would just get something else. Form 1s have been taking 3-4 weeks right now so why not? |

Super weird looking, but probably the most natural/comfortable firearm I have ever fired.
Also spend the $200 on a tax stamp to SBR it, the tiny bit of awkwardness from the 16" barrel disappears. Rounds are pricey,.. but not that horrible when you consider there isn't really any "range ammo". I am well over 5000 rounds at this point and never had a stoppage, never felt a need for rollers or really improving anything other than form1 and SBR. |

Why not a CMMG Banshee or Diamondback that takes your existing pistol mags? I have an AR57 upper, expensive ammo that doesn't approach .223. If you want a PS90 b/c it looks cool, rock on.

Honestly, if I was using a AR based platform, I'd rather have 300blk or 556 depending on barrel length. PCC are a bit..... meh? There are some decent narrow use cases, and the Ps90 fits / mp7 fits them well. Ps90 again is something people want for those reasons... brrrrrrrrrrrrrrrrrrppppppppppppppppppppppppppppppppppppppppppppppppppppppppppp |

I have a short PS90 SBR and a 12in AR57 upper, and they both work well. The AR upper is more awkward for mag changes because its a larger/longer weapon to manipulate mainly.
AR57 is nice because with a newer shooter, the manual of arms is mostly like the AR, so its easy and intuitive to pick up. The P90 SBR is just plain cool. I wouldn't feel undergunned with Elite Ammunition S4UR at around 3100FPS, and a short, handy, virtually no recoil PLUS 50 rounds on tap, if i had to go across the Downtown badlands. Out in the open (200+ yards/meters) its a bit underwhelming, but out to 150-200yards I'm pretty comfy with it. |

I haven't tried it in my AR57 12inch yet, but it should be a little more spicy on 12.5in vs 10.5in barrer on the PS90.
I had a weird issue where all 3 of my Geissele triggers (the top of the hammer actually) would drag on the bottom of the BCG. On 2 different lowers, PSA and Noveske. I thought it was the bolt catch at first, so I milled it down just a touch, and thats when I figured out it was the hammer. Switched to a Larue 2 stage and its not dragging anymore, I just haven't had time since the lockdown in TX hit. |

These rds are so small & the mag opening so tiny & the last 10 or so rds require a bit more pressure for my ham-fisted ability. Still look forward to shooting it when my optic comes in. Not looking forward to loading more mags though.
