FNH PS90 or MSAR STG 556?

First, I've never owned or even touched either of these (yay California!). So all the information that I'm offering is second hand. But according to the reviews I've found online, the MSAR isn't very good, especially for the price. The PS90 is better, but still quite expensive (once you factor in ammunition costs as well).

According to multiple reviewers, the accuracy of the MSAR is anywhere from 3 inches at 10 yards (30 MOA) to 6 inches at 50 yards (12 MOA). This sort of performance is... well... really really bad. And there have been reports of feeding problems as well. These sort of problems are fine with a $400-$500 dollar rifle, but really not acceptable with a $2,000 MSAR.

PS90 users report a much more reliable feeding mechanism, along with better accuracy. Seems to be 1.5-2 inches at 50 yards (3-4 MOA). The ballistics of the 5.7mm cartridge are a bit less than satisfactory when compared with the .223 Remington, and at 100 yards you might experience 5 inches of drop. So you'd be limited to a shorter range carbine.

It's probably also good to point out that there are many cheaper, more reliable, and more accurate firearms to choose from. The Kel-Tec SU-16 is a 2-3 MOA carbine, yet only costs $400-$500. The Target Mini-14 is a 1 MOA rifle, and is half the price of a more expensive gun at $1,000. AR-15s are also an option, and target variants can be extremely precise.

Pretty much all these rifles, the MSAR, PS90, SU-16, Target Mini-14, and AR-15 are all in the same class. All are semi-automatic rifles. I can't really explain why the MSAR and PS90 perform worse but cost more than the SU-16, Target Mini-14, or AR-15.

I think it might have to do with the word "tactical". That's worth $1,500 by itself. :P

I dont know what a MSAR STG 556 is, but i can tell you that a PS90 is not the way to go for a tactical weapon.

First of all, the cartridge sucks against people, unless you have a huge stock of LEO and military SS190 ammo, which is not sold to civilians. The common sporting round is not adequate for use on people.

Besides, any gun you get will likely have a barrel that's over 16", and you can get a 5.56x45mm carbine that is roughly the same size, has more power, more available ammo, and more accessories.

If you're looking for a bullpup rifle stick with an AUG, if you can't afford one then buy a knock off like the STG. Now just an FYI, Pre-ban AUGs run around 4,000 but they just started remaking them for around 2,500. So you got a couple of options...new production AUG or knock off STG.

As for the PS90, it's fun to screw around with but the 5.7X28 is over priced and is about like shooting a .17hmr in my opinion. They say it's deadly out to 200yrds but the 5.56/.223 has more power and accurate out to 400yrds or more in a well build AR. The 5.7 ammo is roughly TWICE the cost of .223/5.56. You can reload the 5.7 brass but from what I hear you can only get 4-5 reloads a piece. .223/5.56 if taken care of can easily handle way more.
