Hi,

I just want to post some initial info but more to follow.
I have a Gen 1 TAR-21. Since I have the rifle, my grouping at 100 m was about 4"-6" (no matter what ammo I was using - AE223, Federal GMM 69 gr, etc). Match grade or bulk ammo did not matter, the grouping was awful. Anyway I shot the factory barrel out after 15,000 rounds.
A gunsmith did a barrel change for me using a Green Mountain SS barrel.
After the barrel change, my grouping stayed the same.
So I sent the rifle back to the gunsmith and asked him to do some tuning for me to see if the rifle could achieve less than 2 MOA grouping. After some initial testing with Federal GMM 69 gr ammo (front and rear sandbag support), the best grouping is 1.16 inch at 100 yards. The main issue - Tavor barrel is thin and it needs some support to 'damper' the harmonic. So a free floating barrel does not work on my Tavor.
I am sending the OEM telfon part and the holding pin to the gunsmith for further testing. More news to follow.

Just want to get this post out there for the guys who have been getting large grouping with their Tavor. There is hope!
 
like taking a Civic to the slat flats and trying to break 200mph. not what the gun was designed for, it is a combat weapon and the groupings are "mil-spec" not MOA. you are gonna spend lots of money to shoot close to MOA with expensive ammo. just enjoy it for another 15000 rounds the way it is.
 
I consider anything less than 2 MOA will be great for a battle rifle. I occasionally shoot in matches that have a 12" target at 400 m. I can beat lot of rifles in the turn and shoot style engagement but I lose as soon as it go long distance. I am hoping the tuning will even out the odds.

For a bolt gun, I expect sub MOA capability for me to get on the podium.

1.16 MOA isn't terrible in a battle rifle... It's not a bolt gun!

Still, I'm tagging this for future!

Well, I use the Tavor to shoot in matches that have short and long distances. Short distances - no problem with the Tavor. Long distance is where I lose out.
Considered how much money I have spent on ammo and gear on the Tavor, the tuning will not cost that much.
Expensive ammo - I have already estimated a reload that will be close to the Federal GMM 69 gr - just need to test the reload with the newly tuned Tavor.
Your intended use on the Tavor sounds different than me so 4-6 MOA may be good enough for you. However, for me, it is not.

I have not seen a heavy barrel for the Tavor. One thing I know - the barrel diameter must fit the gas system. Original space in the Tavor is pretty tight. Also, a heavy barrel will change the balance of the Tavor - I like the existing balance (rear heavy).

I like the concept of heavier (and hopefully more accurate) aftermarket barrels for the Tavor. Does no onemake them?

Most military grade ARs shoot 2 to 3 MOA with M855 balls and about 1 to 1.5 MOA with factory match ammo made by a variety of manufacturers.

Anything that does better than the above CONSISTENTLY WITH MOST AMMO IN THE MARKET is a match grade barrel.

But I paid $30k for a Civic it should do 10 second quarter mile!!!

I've seen some ultra slow-mo vids of the Tavor shooting and it's very surprising just how much the barrel flexes and moves around - almost like watching an AK in slow motion. ~2MOA is best I've been able to do, below, with my own handloads - hey at least it looks good next to the SVT LOL.

i have managed to shoot close to 1moa with 1 load consistently. Unfortunately it is expensive factory ammo, not something i would want to use for everyday shooting.

Its really unfortunate that there's a certain percentage of the gun culture who feel this way because they enable manufactures to test the lower limits of performance. Hey as long as the gun looks cool it will sell to people who will accept cool looks over real performance. By real performance I mean reliable and at least reasonably accurate.

Even a plain old AR15 will shoot 2 minutes or better and its also a plain old mil spec rifle.... unfortunately restricted though.

I think the root problem with accuracy of many of the new crop of modern guns is the piston gas system. While purported to be more reliable, it does so at the cost of increased weight. More specifically.. increased mass being displaced by the gas system and that translates to increased down pressure on the barrel as force is generated through the gas port. This heavy side load on the barrel is why accuracy goes out the window.

That's one of the rarely discussed advantages of direct impingement gas systems and one of the reason the AR is more accurate.

But people who don't understand this consequence keep rooting for piston driven systems to replicate AK reliability. Not realizing the trade off being made at the technical level.

The same can be said for the quick change barrel systems, which cannot be relied upon to keep the barrel pointing in the same direction.

There's any number of military rifles that were produced over the years that were very capable of 2 moa or better and no reason this would be unreasonable to expect from a $2600 rifle.
