SHOT Show SIG Range Day – CSASS Submission

Here is a quick look at the SIG SAUER submission for the US Army Compact Semi-Automatic Sniper System. Based on the MCX platform, it is considered an MCX-MR for Mid-Range.


This rifle met all requirements for CSASS including weight, length, and suppression. It can be side charged or via the more traditional, rear charging handle.


As you can see, it is equipped with a folding stock.


While the commercial MCX is now equipped with a self regulating gas valve, the CSASS model is a two position version that is marked on the rail.


It is a full auto gun as well.


Internally, there is another difference than the standard MCX. Rather than dual springs the MCX-MR uses a single operating spring. However, high wear points such as the steel cam path inset.


Additionally, they’ve incorporated replaceable dual charging handle pins.


The MCX, regardless of class, also offers a replaceable Deflector/ Forward Assist Housing. This includes the 7.62 gun!


Another high wear area that has a replaceable steel insert is the feed ramp insert just below the ejection port.


Finally, as we mentioned during AUSA, the barrels incorporate the new tapered flash suppressor and suppressor mount.

    Looks nice, would like to see how it shoots. But I feel the Army is married to Knights Arms, and this is to modern for US Army to adopted and and issue. If anything comes out of the CASS it with be a shorter M110 and an adjustable stock.

      They churched up their M24’s so I don’t think it’s too far out of the scope of reality. But, I do agree the money invested in M110’s that are already bought and paid for, and, can be run through an arsenal upgrade program will be fairly tempting.

    Hopefully it works better than the Sig 716 they tried to sell to the Czech Army. I’ve heard mixed things about the reliability of Sig USA built rifles.

    Pick a charging system and bring it to the civilian market. I don’t see why these companies even attempt to market to the military , especially the Army. I mean look at the camo fiasco or the waste of time that the whole carbine competition was. The Army will stick with the M110 .

  4. DSM says:

    Methinks that stock hinge might be a knuckle scraper if using that rear charging handle.

  5. BADDFROGG says:

    I am really impressed with this rifle. I can only hope they bring it to the civilian market.

  6. Tackleberry says:

    Hopefully we see a semi offering for the public sector, like a lot of what they’ve done with it.

  7. Squirreltakular says:

    Wow. Looks like the Good Idea Fairy was working overtime at Sig. I think I’m in love.

  8. Tackleberry says:

    Is this thing 7.62×39? If so are they even rounds developed for that caliber for the CSASS role?
