I own a tavor gen 2 with an elcan spectr dr, here's what i can say after about 800 rounds through it:
Cons:
1st: Ammo: you need some hot ammo in this rifle, something over 3000fps otherwise it just opens up way too much at 100. I find when I'm shooting 3200fps55grain I'm running a 2 moa group at 100 yards, weak 2800 fps 55 grain I'm at 6 moa, heavy 69 grain sierra match king i'm at 4 moa.
2nd: Trigger: yes the trigger definitely needs some work, maybe a trigger pack will be available in the future, theres the spring trick, but I don't like messing around with a rifle like that. It's a military assault rifle, I don't care what people say, that spring is absolutely there for a reason.
3rd: Prone or bench: Bench shooting is a bit awkward, I keep hitting the bolt release latch.
4th: MONEY: price, 2700$ for at best a 2moa rifle, a bit tough for the ordinary joe.
5th: Aesthetics: looks weird (if looks are important to you when slugging lead down range, for me looks are only important when it comes to my women, but hey seems like some guys like to have ### with their rifles so...)
6th: Mods: After market or 3rd party parts are pretty much non-existant. It does have 2 rails, so optics and essentials are not an issue, but if you want to Rambo up on tacticool, it's not for you.
7th: Recoil: yep you'll feel that recoil a bit more than on an AR, feels like you're shooting 7.62x39 instead of 5.56x45
8th: Fast shooting: Just couldn't really get the handle of it, trigger doesn't really allow for it with it's 12 pounds pull.
Pros:
1st: Classification: Non restricted
2nd: Balance: Weight distribution is absolutely awesome, feels like you're running something that weighs a third of it's weight
3rd: Hold and target acquisition: Very easy and fast to hold steady if you use the israeli grip (forearm of supporting hand leaning on handle), I suggest strongly sighting in at 50 yards, makes 100 yards easier. Just have to remember to shoot a little higher when at 25. .
4th: Action: Reliable heavy piston driven, bolt doesn't get dirty much
5th: Cleaning: extremely easy to field strip, 20 seconds to disassemble and put back together. Full strip gets a little tricky with the firing pin (if it's the spring mounted one), but once you get the hang of it it's ok.
6th: Reliability: Built to withstand a lot of abuse in its ordinary use, it was built for amphibious beach landings (Salty sea water, sand)
7th: Power: 18.5 inch barrel on a 1/7 rifle that is shorter and easier to handle than a 16 inch 1/8 barrel AR
8th: Shoulder: long length of pull, I'm 6.2 with long arms, lop is important for me!
9th: FTF, FTE, Stove pipes, light strikes, whatevers: Not one single malfunction in 800 rounds, but the casings have a very little slight indentation in them and the neck is flat on one end, could be the brass deflector, but I'm not sure, the indentation is on the same vertical line as the flat neck, maybe the extractor? I dunno, I need to research.
10th: Lefties: Fully ambidextrous, safety, ejections (my wife is a lefty, it's important for me)
For me it was a sure thing, I just had to get one. I was considering the xcr till the point where I put the XCR to my shoulder, lop was actually shorter on the XCR with stock fully extended than the Tavor Bullpup! Imagine that! XCR just felt really flimsy and cheap, (just my opinion guys, it doesn't mean it is, I just felt like it was)
