I don't know, Mike. Maybe you've got a really well put-together Tavor, or perhaps you've brewed up a very good load. You've got to admit, though, that there are far more shooters here that report 3-4 MOA that report sub-2 MOA. With the same scope and same ammunition I was consistently 3–4MOA with the two Tavors I've owned and 2–3 MOA with my FS2000.
I think a big reason most guys on here can't get better than 3-4 moa is because they 1. don't know how to shoot, and by that I mean don't know how to properly support the rifle or don't use proper breathing and trigger control 2. don't realize that every barrel is going to respond differently to a type of ammo so they think that just because Mike's rifle shot 1.75 moa with V-max that their rifle should do the same 3. Don't have a clue and use cheap bulk surplus ammo and expect it to group well or worst of all 4. Are using Norinco ammo and expecting consistency.
I'm not trying to say the Tavor is actually capable of much better than 2 moa but there are a lot of factors that go into making good consistent groups and I doubt there are many people on here that could consistently make tight groups even if they were given my 223 bolt action that can shoot 5 rounds touching at 100 yards if the shooter does their part.
If you are shooting off your elbows or using your body as part of the support system for the rifle then forget about tight groups.
Don't get confused and think that just because the Tavor or any other rifle costs over $2000 that it should magically be able to shoot 1 moa or even close to it. These rifles are doing exactly what the designers intended them to do. If you can hit a 12-16 inch plate at 300 yards it's working perfectly as designed. These are battle rifles and I've never seen it stated anywhere from the manufacturer that they can double as DMR or sniper rifles.
Enjoy it for what it is and don't worry about what it isn't. If you want sub moa then buy a quality bolt action and learn to handload, bring your Tavor with you when you go shooting for some fun while you're letting the barrel of your precision rig cool off.
This goes for most battle rifle designs, very few are capable of consistently shooting 1 moa or better.
Master G, this was not aimed directly at you, I only quoted you because you had similar comments to a few others. I have no idea how you support your rifle or if you do or don't know what your doing behind the trigger. It was more to try to answer some of your questions than to say why your rifle doesn't shoot better than 3-4 moa
