I've always been a fan of Bullpups ... 20+ years ago I was able to get one of the 2nd generation of AUG's more commonly called the USR. Except for the pre-ban features I feel its the ultimate Bullpup.
3000 of them were imported before Clinton in-acted the barrel ban in 1997 by executive order and stopped its importation. It has a odd thumb-hole thingy in front of the mag, the 18' barrel wasn't threaded and they removed the nub for the quick change barrel ... it complied to the 1989 import ban by executive order by Bush/41, just as the MAC-90 and a hand full others skirted the issue.
Since then I've owned a couple of the Special Receiver AUG's and finally one of the 62 green AUG's sent back to Austria with the upgraded 2nd generation receiver which bore the original serial number so was still classified as a preban, they were returned in a new factory box with new owners manuals & test targets ... and the new scope that featured the "donut of death" with a cross hair that is also set up for range estimating.
The Tavor took the US by storm ... I owned one briefly. After being underwhelmed by its 13 pound trigger and realizing it would cost another $350 for a Geiselle trigger another $150 for a raised sight rail that was compatible with standard optics (the factory sight rail is on the same plane as the cheekrest) the forend also left a lot to be desired but I don't recall its cost as I didn't buy one ... but all that on top of the premium price they commanded ... I sold it quickly while the demand was still high.
It left me with such a huge let down I didn't buy into the X95.
I had a FN PS90 which I felt the ammo was expensive and anemic ... the only way to make up for that was in volume ... so if it wasn't full auto it couldn't make up for its shortcomings. Didja ever notice in Stargate SG-1 they never fire just one round? Lastly for the FN's, I've handled the FN FS2000 but it was like shouldering a 3foot long 2x6.
Before the AUG I had a Bushmaster M17S which was ok but even heavier, I always felt it was a poor man's AUG.
I've had the Valmet M82, which is a 7.62x39 AK variant and I really liked but its composite shell (much like the AUG) is known to be brittle and there are no replacements so it was a safe queen for 20 or so years.
Another AK variant Bullpup is the AKU94 which was a kit to transform a standard AK into a bullpup ... it had the spongiest trigger of any bullpup I've ever shot ... I think I still have the kit in a box somewhere along with the gas tube that has a picitinny rail on it (another bad idea).
Anyway, if you want a bullpup, do yourself a favor and get the AUG A3 ... there are a couple different variants but save up a little longer if you have to and you'll most likely be money ahead.
Here's an old picture of a few 'pups I had all at the same time; Top right is the AKU94 , next down is the FN PS90, then a highly modified Bushmaster M17S and on the bottom is the lone survivor my A2 AUG in a NATO stock with the factory scope instead of the optional picitinny rail
