If you had an ACOG which PS90 would you buy to mount it on?

1- Tri-rail

2- USG

2a-Which mount for the USG?

(This would likely be a 1.5x ACOG-BAC and supported with laser and illumination)

Thanks :)

I've said it before - I still think getting a standard PS90 - taking off the stock optic, and mounting what ya want is better than getting a tri-rail.

With the standard - if U need the optic for something else, you can still mount the stock optic back and have use of the gun. U also get backup sights - which the tri-rail does not have...

Thanks all for the input thus far. I am not dead set on the ACOG but I do love the optic, second choice might be their 42mm reflex but I do not care for the 6.5MOA dot which seems to the only option for it. If someone has a different but equal suggestion or thought I'm all ears.

If I go with the USG/standard it seems that my options for adding illumination/laser would be limited without adding all kinds of extra mounts for rails, or am I missing something?

I guess I should note that my goal is to end up with a rugged, ultra reliable & fast sighting system with at least two lighting options (f/o, tritium first choice, led last choice). A rugged, ultra reliable lighting system, and a rugged daylight laser that can also double as a non-lethal/distraction device. The deciding factors in order would be reliability, ruggedness, weight.

And no I'm not looking to play commando, I've just decided that I want one decent weapons system that I'm going to run until I croak. Ive done the M4's, AK's, FN/FAL, Glock's, HK's, Sig's, 9 vs 40 vs 45, etc, etc, etc, blah, blah, blah. After years of all that I fell in love with the 5.7 PDW/pistol combo and want to just simply by setting these up good and not messing around any more with the others. The rest of the toys are gone with a few exceptions that are more sentimental than anything else, so the 90 and 57 will be my primary home/vehicle defense weapons as well as my fun plinkers.

I am open to any input or ideas that you may have so use me as your "If could do it all over again" :x

Thanks


(ETA, I will be doing the SBR on the 90)

2 side rails to attach to the standard PS90 isn't very expensive - but yes, you would have to buy side rails.

I too like that Reflex sight - but the 6.5 MOA is a killer for me too.

Farmer Ted: We think along similar lines. I, too, have been down the M4, AR, AK47, AK74, HK91 roads and found myself dissatisfied w/all of them for various reasons. Finally, the PS90 came out and w/the companion FN57 USG appears to be the closest platform to my "ideal" setup. I'll try to address you points as best I can with the answers that worked for me.
1) Optic: I would dearly love the ultimate KISS optic that needs no controls, brightness adjustments, batteries to replace, electronics to fail, is good in all lighting situations, etc. Unfortunately I've yet to find that optic and after having tried the Eotech, Russian PK-AS, Aimpoint M4, Trijicon Tripower and finally the Aimpoint ML3 I decided to stick with the ML3 in the TROS ultralow Aimpoint mount. Why? Aimpoint's combat-proven reliability & insane battery life (literally 5+ years of constant 24/7 use on a single battery) plus the single rotary brightness control is much faster/easier to use than the Eotech's or Tripower's buttons. The TROS mount is the most rugged optics mount for the PS90 that I'm aware of (4 screws instead of the usual 2) and it mounts the Aimpoint as low as physically possible thus ensuring excellent cheekweld. I will be happy to discuss the flaws of the other optics I have tried if you wish more details.
2) Taclight: I went with the Streamlight TLR-1 because it's an LED so no worries about it breaking/burning out at an inopportune moment, remote backplates w/different tapeswitches are available if desired, puts out 80 lumens which is plenty bright for my CQB needs and it's small/lightweight so doesn't hinder the handling qualities of the PS90 and 2 spare batteries can be kept in the oiler compartment behind the PS90's buttplate.
3) Laser: While I like a laser for lowlight/nolight situations I am not convinced of their utility for daytime use. I opted for the P90 internal laser which, while pricey, places the emitter in a protected location that's also centerline and very close to the bore thus minimizing parallax problems with POA/POI. It also uses the same battery as the TLR-1. If I couldn't have the P90 internal laser then I'd probably opt for the Streamlight TLR-2 combo light/laser and learn to deal with the parallax.
4) Reliability: I've had my PS90's for over 2 yrs now and they've been 100% (even when deliberately left dirty for over 1,000rds) except for a strange FTF problem that was directly attributable to the mag. I've had no failures w/any of the lights/lasers or optics, this is one of the few platforms I've owned that I trust completely.
HTH...

Just a couple of weeks ago I did just what you are asking about. Took a White Ring PS90 and mounted a 1.5 ACOG on it using the TROS mount. Great setup. I like it much better than the White Ring even with the REM 2 installed.

I do not know much about the TR as I do not own one but the setup I have is "perfect" for me.

i would stick with some sort of red dot/reflex sight, trijicon has a reflex sight that has a triangle reticule that really works well but its like 13 moa. all you do is sight it so that the tip of the triangle is your POI and you are good to go. we used a couple of these in iraq and they were pretty nice. aimpoints are always a good choice and alot of people like eotech which i dont particularly care for. acogs are nice sights but way over priced for what they are. i was issued while in iraq, it helps when shooting at targets 200-300 meters away but for a PS90 its almost limiting its capabilities because its not exactly a quick aquisition sight if you know what i mean.

Well it looks like I'm going with a USG white-ring, a found some priced at $1,200 which is the lowest I have been able to find for NIB. Now that I understand a bit better being able to add side rails to this model I dont see thew point in spending ~$400 more for the TR.

Anything I need to be concerned about with an early white ring PS90? Have there been any mods or improvements made?

Nope. Both my PS90's are early white rings, just removed the ringsights and installed the optics rail of my choice along with a side rail for the taclight. If you can operate a hex wrench then you'll have no problems. Have you made a decision as to the replacement optic/mount yet?

K here is a new thought...... :eek:





With a set of flip up front/rear iron sights mounted fore/aft of the DOCTER red dot on a picatinny rail, I'm sure I could find a set with tritium inserts that would work nicely. The DOCTER seems tough, fast, with a large FOV, light weight, good iron sights, tritium for night/back up use.

Thoughts....?

I have yet to use the sight on a PS90 but have played with the Docter, it seems as if the Docter actually has a lager lens than the stock sight, can someone confirm? I very well may end up with one on the Fiveseven so the commonality might be a plus.
