IWI's 20 Inch barrel version of the Tavor 7 is starting to show up on US websites.

I know that the  page has been up for at least a month. Buds is the only place that I have even seen it listed here in the States. I'm not holding my breath but waiting patiently.

So IWI is not going to produce the 18.5 and will go with the 20?

Good question. I have heard both lengths being sold. One was that the US would see the 18.5 & that the 20 was a Canada only model. Me, I'm still hoping for a 20 inch model.
I'm not on Face Book anymore so I have no Idea what has been posted on the T7 page, or by Jeremy Gresham.

Ballistics differences between 16" and 20" 308W/7.62x51 common mil-type loads are negligible.   smiley dance

I'm not looking to get it for the difference in ballistics. I want it because I like the look, have a scope & a bi-pod looking for a new home.

If you handload the 20 inch can get substantially higher velocity with a slow powder like aliant 2000-mr.

Most of what I have seen is about a loss of 25 fps per inch of velocity from 20 to 16". So about a loss of 100 fps from the 20 " to 16".
I guess some range time will show if there is any significant differences (which I personally doubt) once I get one .

But as I said, I'm not in for this for any advantage in ballistics.

I picked up a 16 inch T7 only because I was under the impression from IWI that the  20 inch was for Canada only -- much rather have a 20 inch and as soon I can find one -- I'll get one.  The 16 has some advantages like being in a dense wooded area where you have limited swing  / pivot movement - but for open field, the 20 inch is the way to go.  Here is a graph I found and some data points.   first row was 147 gr Winchester.

20 2804 2679 2565 2478
19 2757 2634 2532 2441
18 2739 2595 2523 2411
17 2707 2577 2481 2401
16.5 2682 2561 2466 2373
AVG velocity loss fps/inch 24.6 22.8 20.9 22.5

well had a picture of a graph but - don't know how to upload -- but anyway - 20 inch here I come

and buds -- well they are showing the old out of date picture of the T7 with a 16 inch barrel -- just trying to get some publicity -- personally - be the last place I would go these days

The 20" will serve to make the rifle longer & heavier, defeating the concept. Only benefit would be longer range accuracy. But not being a free floated barrel, I don't see it achieving any better than the "combat accuracy " it produces with the16.5". Now if they changed the design & implemented a free float barrel capable of precision accuracy, I'd have a second rifle bought tomorrow!

Funny, last I checked it will still be shorter than most rifles with an 18" barrel & definitely shorter than standard rifles with 20" barrels. This might be why the military is looking at the General Dynamics new bullpup with a 20" barrel.

As to accuracy, we shall see.

Still longer & heavier than the original offering. The current design of the T7 doesn't produce repeatable/precision accuracy,  nor was it designed to. I believe IWI did go back to the drawing board early on to improve accuracy of the T7, but claimed they could not without compromising reliability.  Not why I bought one anyway. Hadn't seen the General Dynamics offering yet, sounds interesting.

I thought the military was looking at the General Dynamics rifle because it shoots a composite-cased cartridge in 6.8mm? I don't know to much about that round but it appears they are exploring other options than 308. Soon enough well see how the trials go.

On the T7 just before the plandemic a guy called me and had a brand new 16.5 T7 at cost and I passed on it as I wanted a 18.5. I'm hoping that wasn't a mistake. I'm still holding out for the 18.5 in the States and not the 20.  Everyone has there reasons and for me I have a 14 and 16 inch Tavor and now I want a 18 incher to incrementally complete the Trio.
