I realize this is a bit of a dated thread, yet for all the negatives that you’ll read about for both the Tavor & the Aug (not necessarily in this thread, but on the internet), you’re generally reading from guys in their mom’s basement as both the Aug and the Tavor have plenty of real world combat experience. Sure, the M4 far outpaces both with the # of units deployed and probably shots fired in anger, yet keep in mind that the Aug design is almost 50 years or so (1977, I believe).
I own both, as well as a safe full of M4s and they’re really designed for different purposes. You either like bull pups or not, i guess, yet I have zero problems with cqb type stuff with any of the three, and with the right sights, you can easily reach out to 300-400 yards with typical solider issued sights, further with SDMR type sights. Steyr came out with a NATO stock for the Aug which allows you to use all those PMags you’ve got squirreled away, yet both of my Augs are the “Aug mag” (The Aug is a proprietary polymer box mag - not sure if it has a name). I can tell you I’ve never damaged one, although I’m also not humping my Aug and its associated mags through challenging conditions. The OP in this thread (years ago) said he was looking at branching out and trying something new, so go ahead and do the Aug mag. Lol.
The manual of arms is different for both the Aug & the Tavor, and the balance is different than what we’ll all probably used to, yet you can get used to them with practice. If I were going in harms way, I’d probably take an M4 but that’s only because of personal experience and likely supply chain issues. For a range toy? Absolutely, you should get an Aug. And a Tavor. I have both an original Tavor, the X95, and a Tavor 7. I routinely hit steel silhouette targets at 300 yards with them.
