FNH PS90 Bullpup Carbine

[GlockConvert]

Not quite sure what the purpose of the AR is. If you have an AR sized weapon, why not get it in 223, which is a much more powerful round. In its civilian form the fn round is basically a 22mag. Seems like a small round for such a big rifle.

fn2000 I have been eyeing one but they will likely be banned before i can work my way down my gun list far enough to get one.

if i ever get a bull pup, it would almost certainly be the fn2000.

Yeah that one has caught my eye much more than the PS90. I just don't care for the elephant snout thingle ahead of the trigger on the PS90.

I handled an OD PS90 at SW today, it didn't feel as akward as I imagined. I am hoping a range around here might have one to rent...

that is the most brilliant thing i have seen in a long time. . .

Is there that much of a difference in power/lethality between the 5.7 and the .223 / 5.56?


...and I wonder if it would be practical, at the range, to put some sort of bag below the mag well on the FN conversion... you'd capture all of your brass easily for reloads...

[Wild Rice]

The reason for the AR-57 is that I am not allowed to shoot an AR-15 with .223 ammo at my indoor range, but I am allowed to shoot 5.7 at the same range. I know because they rent a full auto short barreled version (the FN P90). This is one way to regularly shoot an AR. I like this 5.7 conversion better than 22LR conversions or 9mm top ends.

The 5.7 has some value as a self defense round. It was designed as a personal defense round for tank personnel and behind the lines troops with the ability to penetrate light body armor. Energies close to pistol rounds with less recoil. Not overly penetrative (in civilian guise) and not deafening when shot indoors like .223. I want one primarily as a fun range gun/plinker.

People are talking about modifying an empty AR-15 magazine (follower, spring, and mag lips removed) to serve as a brass catcher without the gun having a scrotal sac attachment. Can't say if this would work, as no one can get their hands on one yet.

I would love to have a P90. Something small and compact like that even with a 16" barrel would make a great compact ranch gun. Cross body sling it across your back and it would be good to go.

One day MAYBE. The thing that scares me off is FN pricing.

I went to a gun show and found a NIB PS90 black Triple Rail model for $1499. Instead of the small field of view optic, there is a standard rail for your own optics. FNHUSA also has a deal on PS90 TR's for a free C-More optic. I did not want to wait for my free optic, so I picked up an NcSTAR holographic optic with unlimited eye relief, variable intensity, lithium battery, and 4 dial selectable reticles for $52.

I just missed out on an olive drab white reticle PS90 with five! 50rd mags and case included for $1299. But like I said, I do not want the white reticle model and I hesitated.

I have also started collecting 50rd PS90 mags, so I am ready when (or if) the AR-57 surfaces. The PS90 came with one 30rd mag that can be converted to 50rds and I bought two 50rd spare mags ($60 each) as well as a PS90 specific soft case ($45) with three long mag pockets.

Despite the high cap mags, I decided to shoot 5rds at a time to make the shooting session last longer, to shoot better groups, and to practice reloading. I shot 150 rds with perfect function. The hollow point load is much peppier than the blue tip ammo. Loading the mags is easy once you find out the best place to press the round into the previous seated round. The gun is not designed to lock back after the last shot so I counted 5 shots, remove the mag, and checked for a clear chamber after each 5 round group. To see the chamber, you need to remove the mag; do not get lazy on this safety point! To load you must press down sharply and hear two clicks. At one point I did not press down hard enough, but knew it did not sound and feel right. I just pressed harder and it clicked in. I have gotten into the habit of sweeping my free hand across the top of the mag after inserting a mag to make sure it is even with the rear stock.

The trigger was a bit stiff at first, but by 75 rds, it had broken in nicely and was smooth, moderately weighted and crisp on release. The bottom ejection was brisk. If you hold the support arm close to the rib cage (target form), the shells can hit you in the belly. If you shoot at the bench, they can end up in your lap or on the seat. If you shoot on a concrete floor, they can end up under your feet. Besides wiping off the seat, it was not a problem.

I was disappointed with the accuracy as I was getting shots walking off target. I traced it down to me not setting the set screw on the windage correctly. Once I figured it out, I shoot a few tight groups at the end.

Take down is ingenious. Remove the mag and pull the cocking lever back and check for clear, then let the bolt go forward. The gun is disassembled in the cocked condition. Do not pull the trigger. With the push of a button the barrel group slides out followed by the bolt group. Slide the recoil pad off the butt, flip a lever, and the trigger group slides out. This makes cleaning a snap.

One thing that I noticed was that there was some play between the barrel and upper receiver. There is definitely a few degrees of rotatory play and minor rocking. The barrel actually has a long shroud/flash hider screwed on the muzzle. This shroud completely covers the barrel from the receiver forward. The play was between the shroud and the front of the receiver. Since the rail is one piece with the receiver and the shroud is connected to the barrel, this play is detrimental to accuracy. I was able to wedge an aluminum shim between the flat of the barrel shround where it meets the front of the receiver. This took out 95% of the play. However, I have since learned that this nbarrel play is normal and the gap should not be shimmed. I removed the shim before test firing and do not recommend that the play be shimmed. The problem is probably with the windage set screw on the cheap optic. I found that in order to tighten the set screw properly I had to push the rear of the sight body to the left against spring pressure. Hopefully the PS90's second session will prove to be more accurate than its first session.

The dealer who sold me the PS90 mags is awaiting the AR-57, as many of us are. He expects it soon, but I am not holding my breath.

Edited: Barrel play is normal and shimming the barrel is not recommended.

You will damage the receiver if you keep the shims in there and keep firing the weapon. You do not want weight on the barrel when firing, and you do not want to stop the movement of the barrel. This would have been part of the cause of your accuracy problems, I would say.

Also - by not having the windage screw set right - that was part of your problem.

I've had my PS90 since Dec 2006. In Dec 2007, My groups were starting to suck. At almost the end of the session, after I kept having to adjust the windage - I finally noticed the mounting screws on my aftermarket rail (I have a standard PS90) had vibrated loose after 1 year. So, I went back home and rethread-locked them. I resighted in my optic again, and now I am back in business.

I can get 1/2" groups at 50 yards.
