Remington MSR: The Special Forces MK 21 Sniper Rifle

In 2009 the Precision Sniper Rifle program gave birth to the Remington MSR, a modular sniper rifle that was capable of getting good hit out to 1500 meters. In this episode of TFB TV, Patrick takes a closer look at the same rifle that he used when he shot the man-sized target at 1760 yards. The Remington MSR won the Precision Sniper Rifle competition and became the Mark 21 sniper rifle that was adopted by the US Special Forces as well as special forces units in Brazil and Columbia.

    Video was great as always. Just nothing to exciting from Remington….

  • Ragged Hole

    Love the channel and the video but am trying to figure out why this gun only shot 1.25 groups @ 100yds… Off the top of my head I can think of a few military rifles, mainly the M110 and the M14 that would outshoot that and those aren’t even precession bolt guns. I know it has the advantage in maximum effective range but is that really all it can do? I need more data!

    • Patrick R. – Senior Writer

      It was designed around a specific cartridge that I didn’t have access to. I also didn’t have it long enough to develop a load just for that rifle.

      • Rusty S.

        Yes. It averages .75 MOA with 300gr .338 loads if I recall correctly.

        • CommonSense23

          Didn’t Remington already lose the contract?

          • Jack

            Yes. They lost the PSR contract due to quality and failure to meet ship dates. Another Remington contract lost.

          • CommonSense23

            Yeah that’s what I thought, with Socom pushing for the ASR currently. Not surprising, while technically AAC lost the 300BLK contract to JSOC, they were a part of Remington when it happened.

          • Mike N.

            SOCOM should have just went with the Accuracy International PSR contender.

          • Rob

            The other finalists were the FNH ballista and the Sako M10 so they found the AI lacking in some regard. It is a shame that Remington couldn’t deliver the performance of the test guns when they went to production.

            Hopefully they find what they are looking for in the ASR.

          • Aono

            Apparently they switched from Bartlein barrels to their own, which is probably what is afflicting Patrick’s example. Remington doesn’t build quality. It’s like every segment of the shooting market gets to learn this the hard way. The upcoming PSR replacement, ASR (because “Advanced” > “Precision”) in 300 Norma, will hopefully look a lot more like an AR-10 from Falkor with a Proof or Straightjacket barrel, than this POS from Failington.

  • It is my understanding the SOCOM has been very unhappy with the production Mk 21 PSR that Remington delivered. That is why they have already issued a solicitation for its replacement: the “Advanced Sniper Rifle.”

    Go to the USASpending website, and search for Remington’s PSR contract award: H9222213D0003. In a modification dated August 2015, SOCOM deleted $4,886,475 from Delivery Order 0005. That delivery order was originally for “PSR Production Systems” and worth $5,061,848 before the rollback. The only large delivery orders that have survived concentrated primarily upon ammunition. Also note that the contract has gone quiet since November 2015, which is very strange since the base contract duration was supposed to be 10 years.

    Remn MSR aka PSR been terminated – HAHA at Remington

  • Ευστάθιος Παλαιολόγος

    Interesting (and odd) that they are going for 300NM and 338NM and not the more common 300WM and 338LM.
    Anyone knows why is this?

    • Lt M

      .338 Norma can match .338 Lapua performance, and some are looking at the accuracy requirement for the .338NM chambering in the SSN and drawing links with General Dynamics’ proposed .338NM LWMMG.

    • Mike N.

      The .300 WM load they went with (Mk248) is crazy hot, way hotter than SAAMI or CIP, and is really pushing the limits of the cartridge. It’s better to go with a .30 cal cartridge with more case capacity for the performance they’re looking for.

    On a side note: Way to go with Hoppe’s signing on as a sponsor!

  • snmp

    The stock of the MK12 is base the Rifle chassis of Cadex Defense (canada).

  • Stan Darsh

    It costs 3x what the Sako/FNH/Barrett costs AND is made by Remington. Tax dollars hard at work.
