FNH Introduces CSASS Contestant; Plans to Offer Mk. 20 to Civilians

There were some interesting developments at FN’s AUSA 2014 booth. SoldierSystems reports:

At AUSA FNH USA is displaying their Compact Semi-Automatic Sniper System (CSASS) entry. Based on the tried and true SOF Combat Assault Rifle (SCAR) system, FN’s CSASS rifle is essentially the same package they developed for the Mk 20 Sniper Support Rifle selected by USSOCOM. FN also told me that the rifle would be available for commercial sale about a year from now and will be manufactured in the South Carolina plant. If you’ve been wanting an SSR, your chance is coming.

Mk 20 SSR specs:

-Hard-anodized monolithic aluminum receiver
-MIL-STD 1913 accessory rails at the 3, 6, 9 and 12 o’clock positions
-Adjustable, removable folding front and rearback-up iron sights

-Hammer-forged, chrome-lined steel
-Fully free-floating design
-The barrel can be removed and replaced by the operator to facilitate cleaning and maintenance with negligible impact on previously established zero
-Flash hider optimized for suppressed fire

-Non-folding, adjustable cheekpiece
-Length of pull adjusts without tools
-Aluminum and polymer construction

-Ambidextrous selector lever and magazine release
-Charging handle may be mounted on right or left side
-Enlarged trigger guard
-Adjustable gas regulator for use with or without suppressor to maintain felt recoil

The Mk. 20 is possibly the most interesting SCAR variant for civilians, in my opinion. There’s a dearth of affordable, lightweight, reliable, and “practical” accurate selfloaders on the market.

The biggest difference between the Mk. 20 and the CSASS entry appears to be a slightly different forward rail and the addition of a handguard endcap.

      No less than $2800 I’d bet. I’d figure 3k minimum street for some time.

      • BG

        Well I’ll be able to get it in about a month and a half

        • Anonymoose


          • JW

            Yours or BGs? 😉

          • Anonymoose


      • vereceleritas

        Since a standard 17s costs around $2800, I would expect this to be closer to $4000. Firmly in SR-25 territory.

      • n0truscotsman

        Assuming thats true, then thats the cost of a LMT 308…or a larue…

        yeah fat chance FN.

      • Jim

        North of $6000 actually, and if you think I am wrong, wait until 2015 when it hits the market.

        • JumpIf NotZero

          I can’t see it.

          I think you are under-estimating how much the market will slow this and next year. But will pick up again for election.

          I think FN knows if they don’t get their civ shit together thy will start looking like HK.

          • Jim

            I am not under estimations at all, I have friends that work at fn and I own two scars myself. I agree with you completely however and I must say I would rather call mr Barrett if it will be any higher than 5k.

        • JW

          That is probably too high an estimate. Since my Scar 17s hits 800 meters just fine, the price point for basically a longer barrel and cool stock might add another $1000.

          • Jim

            Trust me, I have a lot of friends that work at FN. This is way more than just a longer barrel. Look up on fnforums.net for more Information regarding this model. You will find a lot of info on there. I was the one to give this article to TFB because I heard about it from there.

          • JW

            Thanks for the 411. You’re totally right. My friends confirmed the gas port is in a different spot allowing for the differences in barrel length to not affect accuracy. Still shocked by the price tag. But still want one 🙂

    • Dual Sport

      If a scar light or heavy starts at $3,000 to $3,500 there is no way this is under $4,000.

      • Scott

        You can get a scar 16s for 2300 and a 17s for 2600.

  • Commonsense23

    It would be nice if FN offered a reliable MK20 to Socom before they started offering a civilian model.

    • Joshua

      Didn’t you see! It is Tried and True according to FNH.

  • JumpIf NotZero

    Well…. Already have the Mk6 to go with it I guess.

    Not sure what “Flash hider optimized for suppressed fire is supposed to mean. It looks like a Surefire Socom on there, I suppose maybe they mean it comes with a Surefire socom flash hider?

    Non-folding stock is interesting. I’d also like to see the barrel profile. The original Mk20 profile was not at all confidence inspiriting. With the suppressor being part of the CSASS, I bet they increased barrel thickness.

    • Joshua

      Probably code for muzzle break.

    • Zachary marrs

      Its certainly not made by BRC

  • Commercial sale eh? Well that’s interesting . . . the biggest hole in my gunsafe at the moment is the “Semi-auto .308” rack after saying good by to the old M14.

  • Joshua

    Hahaha…. Hahaha haha….. Oh god my sides, thanks FNH I needed the laugh.

    They don’t have a rain drop in hell chance of getting the CSASS contract.

    The Mk20 has a number of issues even to this day. Also more like tried and true to have stoppages and be one of the least accurate DMR platforms out there.

  • Lance

    Thats the last thing you need this plastic piece of junk. Like the Army may do get a better AR-10 than this.

    Or go my way and get a even better M-14 EBR. As most solders in combat do no plastic and most go for the old 14.

    • n0truscotsman

      A quality AR10 rifle from Larue or LMT will shoot circles around a M14. The 1930s wants its technology back.

      • 100% of LaRue guns I’ve seen at the range have malfunctioned. 😉

        • Joshua

          LaRue has seen extensive use in the SoF community.

    • tfb.lurker

      Classic Lance masturbation style post; all that effort to bear no fruit.

      The EBR, “your way (lol),” was a low-cost, duct tape solution. Once again, another blind follower of, “military does it so it’s validated.”

    • ConvoyScout

      Military M14’s are forged receivers most new civilian side are cast receivers.

  • echelon

    After looking at all the CSASS entrants the Army concludes that none of the new weapons provide a significant enough leap forward in soldier effectiveness so thank you to all who contributed and piss off.


    General Taxpayer Money Spender III

    • Joshua

      Nah, my money is on the M110K1 KAC is submitting as it can be procured as a retrofit kit on the current M110’s.

      I know some in MARSOC have done that.

      • n0truscotsman

        Its much cheaper to do that, despite my personal dislike for the M110 and the way knights armament initially fielded it. Its not my first choice for a rifle in such a role either, and probably isn’t even on the top 5 list, although, for the army, its the best choice IMO.

        There is no point in adopting the SCAR-based Mk 20 since the SCAR is not big army wide.

        • Joshua

          I wouldn’t want the SCAR platform anyways.

          As for the M110 it was the best option at the time and the K1 kits would be a much cheaper option. I would have preferred a LMT though.

          I figure kac will come use the performance of the K1 rifles to demonstrate what the kits can bring at a much cheaper cost.

      • echelon


        But seriously, yes your money is on it. And mine, and his and hers…

  • Colin

    What ever happened to the non-reciprocating charging handle FNH developed for the IC? Its not even mentioned on this.

  • J.T.

    I’m still waiting for the non-reciprocating charging handle from the FNAC to get put on the civilian guns.

  • JW

    Oh…I need change my armor.

  • JW

    For SCAR owners this is what we have been waiting for.

  • Uniform223

    I’ll probably be accused of being a fan boy by saying that Knight’s M110K already has the CSASS in the bag. It has parts commonality, is an easier more cost effective, and expedient “fix” to the M110. Its a simple “drop in” upper receiver change and also its a more mature system as its developed from the SR-25 EMC/ECC.

  • Krautsalat

    How nice of you FN. Now if you would only make the effort to get your civilian products approved by the german gov. and market them to german civilians as well that’d be what made me happy.

    • SD

      No one cares about Germany. How about you work harder at supporting H&K?
