Yesterday I shot my Tavor at a local multigun match. It was the first time I've used it in competition, and I was curious about how it would compare to my ARs. I took 4th overall, and placed 1st on one rifle-heavy stage by a significant margin. While I probably would have done better with my 11.5" AR "gamer gun" just because of all the experience I have with the AR, I was very pleased with how the Tavor performed. It's a viable platform for competition. Here's my setup:
Geissele trigger pack
MI extended handguard
Magpul keymod VFG
MI ejection port cover
Manticore butt plate
SF Mini suppressor
EOTech EXPS3-2
