Fast shipping

Ordered on Friday, got it on Tuesday. Best pricing by far, would purchase again!

Unbeatable deal

A solid range ready package for a BIN price! 2 mags and an optic, for the price of a fancy AR with no sights? No question to it! The rifle shoots well, ammo is close to the price of .223 nowadays anyways, so might as well have something different and exotic.

Excellent with MIR

Gunprime has the best deal on these PS90. Shipping is quick and quality item. Been a customer with them over the 3 yrs and never disappointed with their service and pricing.

Great gun at a great price

Ps90 arrived within a few days after placing order. Made transfer seamless and quick with my local FFL. Only issue was gun needed lubed to allow it to close the slide. A little lube seems to have remedied the issue. Would definitely order from Gunprime again!

Awesome gun, smooth transaction

Awesome little gun and the price was fair. I've been wanting the PS90 since I first saw the P90 hit the screens in Stargate SG-1 back in '97. Growing up in California, even after the '94 AWB expired, I still couldn't get my hands on one of these puppies. Now that I am in a free state, I finally got the chance to pick one up. After 26 years of wanting a PS90, its finally mine! And what an interesting piece of hardware it is! Heavier than expected for something made primarily of plastic, but after handling it I realized that the heft is the "moving parts group" and its is definitely needed for a blowback design like this.

The balance is definitely butt heavy, and its very different than the nose heavy rifles I'm used to. But with the low recoil of the 5.7, I can't imagine there will be any trouble keeping the gun on target. It'll take a bit of familiarization though.

I have a few gripes about the gun so far, and I'll list them out for any potential buyers to consider. However odds are that you have ran across these issues when searching info on this gun already.
1. The bullpup trigger is pretty crappy and not drop safe. Promoted Pawn offers an upgrade service to both issues, but its expensive.
2. The sight sits WAY high. This can be remedied with the purchase of an expensive aftermarket sight base or even by using a magazine coupler.
3. SBR the dang thing! It's pretty goofy with all that barrel sticking out, but that makes it legal for mass sale, so I get it.
4. Mag release should have a higher profile from the factory, but aftermarket parts are available.
5. Charging handle could be bigger, again aftermarket parts are available
6. The factory backup sight is barely usable. really not even worth having
7. It would be very nice if they still shipped with the black ringsight instead of the PIC rail/sight combo
8. FN should have included side PIC rails in the box.

All issues aside (which there are aftermarket fixes for all), it's a great and simple gun that excels at it's intended function as a DEFENSIVE weapon. Lets be real, this is not the gun you take into battle. What this gun is for is getting OUT of battle. Small. lighter than a rifle, more takedown than a pistol, high capacity, high rate of fire, reliable, simple, and super maneuverable. A great defensive weapon that is to be carried when space is very limited and overall weight is a concern.
