IWI Introduces 300 BLK Version of X95 Assault Rifle


Israel Weapon Industries announced the introduction of the 300 BLK caliber into its X95 line of assault rifles. The new military weapons will be shown at the Eurosatory 2016 show in France this month.

Until now, the X95 has been available only in 5.56 NATO, 5.45×39 and 9mm. The 300 BLK makes a fourth caliber option in these bullpup style rifles. IWI US, the United States based subsidiary of IWI, announced earlier in the year that the company would roll out semi automatic TAVOR and X95 rifles in 300 BLK.

Since the 300 BLK was designed to be compatible with magazines and bolts that are sized for the 5.56 NATO, the addition of the .30 caliber round to the X95 line up wasn’t likely to be a huge technical challenge. However, I am interested to see that IWI believes there is enough military interest in the round to make the required R&D and production line modifications and/or additions to offer these rifles.

One of the benefits of the 300 BLK is its ability to run heavy bullet weight subsonic loads that are eminently compatible with sound suppression. For a military unit still running suppressed MP5s, the X95 in 300 BLK offers similar suppression ability with a number of platform improvements. One of the most obvious improvements of the 300 BLK X95 over the MP5 is the flexibility of simply changing a magazine to move to supersonic loads with significantly more power and range than the 9mm could ever hope to achieve.

  • Well you say it was not a huge technical accomplishment but if the gun is to operate with both subsonic and supersonic rounds reliably and have a minimum of a 16″ barrel there would still be a bit of effort in the technical side. The 300 BO was designed around a 9″ barrel originally, not the 16″ barrel.

      Its not very difficult for an AR platform to do that. Why would you think so for the Tavor?

      • I do not think they can shift the gas port around as much as the AR15 can be done. The AR15 is one of the few weapons that has had many different length gas systems. With a g as system where you are pretty much in a fixed position you have a pretty fixed pressure at the barrel at that point and the only variables you have are gas port size and piston diameter. Determining the optimum size for these two are hardly an easy and quick design issue.

      People tend to overstate the whole “designed around a 9″ barrel” a lot. This only means that the powder is usually burnt around the 9″ mark, but the bullet can still get faster father that just fine. The 9mm was designed around a 5″ inch barrel, and does just fine out of a 16″ barrel.

      The challenge would be to have a proper cycle with the low pressure of the subsonic loads, but considering how the Tavor is overgassed by design, it seems doable.

      It was designed around a 9″ barrel, but because of the powder, subsonics barely change when you go to 16, and the 16″ barrel does give you a nice velocity boost with the supersonics.

    They should fix their accuracy issue before doing anything else.
    This accuracy issue killed the X95 for me.

    • andrey kireev

      It’s about as accurate as AK or an M4….I mean it doesn’t shoot 6 inch groups or anything…

      • Kyle

        It is about as accurate as a rack grade AR or AK around 3 or 4 MOA that you can pick up for like $500 dollars. The X95 clocks in at around $1600 or $1700. That is pretty sad for a rifle that expensive. An AR in that price range is going to be damn near a tack driver. Certainly 1 MOA or better.

        • andrey kireev

          Meh, not like you’re going to do any practical shooting, going for 1 MOA groups anyways… I see your point, but at the same time there are plenty of expensive firearms that don’t necessary achieve 1MOA groups consistently… Take for example DSA’s FALs and Krebs Custom AKs

    Richard, the photo you used is of the Integrally suppressed 9mm X95. You can tell by the magazine adapter and colt SMG magazine peeking out.

    • It is what was provided by IWI.

  • Harry’s Holsters

    While I’m alway’s happy to see more options I’ll wait for a MDR or RDB in 300. The ejection options make more since to me for a rifle I’d probably use for home defense.

  • Michael S

    Am I the only one thinking about arma 3 by the photo?

  • HG

    Any idea when we will get 9mm x95 and SBR versions (or kits for those of us who would form 1)

  • Luke

    I would strongly encourage removing the term “assault rifle” from this post unless it is explicitly referring to the full auto variant, which from my understanding it is not.
