For more information, visit


Fresh from its move from Montana to Idaho, Nemo Arms had some really interesting offerings on display at the 2017 SHOT Show in Las Vegas, Nevada. The company made it name for itself thinking outside the box when it comes to firearm design, developing a .300 Win. Mag. AR-pattern semi-auto rifle. Let’s take a look at the newest version of that rifle as well as some the company’s other offerings.


  • Chambering: .300 Win. Mag.
  • Barrel: 24 inches
  • OA Length: 45.5 inches
  • Weight: 10.2 pounds
  • Stock: Magpul PRS
  • Sights: None
  • Action: Semi-auto
  • Finish: Various
  • Capacity: 10- and 14-round
  • MSRP: $7,500


The Watchman rifle comes with a Proof Research carbon fiber barrel as well as an adjustable gas system/regulator for customizing the cycling to a specific round/load. The rifle comes with two magazines and a high-quality drop bag. The manufacturer claims that the recoil of the .300 Win. Mag. rifle is only slightly above that of a 5.56mm.

Price & Availability

The rifle is available for a starting price of $7,500, and the company has a lead time of four to six weeks on any rifles that are not currently in stock. If you need a semi-auto rifle in .300 Win Mag, then NEMO has a product for you.

    $7500 is also in the same price range as a desert tech hti chambered in .375 cheytac.
    I originally had a nemo and sold it to get the desert tech srs chambered in 300 with mag. I love it!

    $7500? That’s right in the ball park of a Barret M82 that shoots a hell of a lot further than a .300 WM will ever do and I absolutely LOVE .300WM. Fail.

    Now, if someone made a .300 winmag upper/lower reciever set and sold those, then the market would get cheaper. Because all you need, I believe from this is an upper/lower, BCG, and a barrel. Everything else should be remain the same. Am I wrong?

    LMAO….2,700.00 for a 300BO pistol, sorry but Nemo is shooting at a very very small segment of the market! Once all the “wealthy” gun owners market is saturated, there will be a very short lifespan in Nemo’s future.

    A 0.3-0.5 MOA, semi-automatic, AR style, precision rifle in .300 Winchester Magnum? I’m in love! Unfortunately this rifle is a lot like Miranda Kerr (the world’s most beautiful supermodel). I’m just about in love with her too, but I’m pretty sure I ain’t ever going to get a date with her, just like I’m pretty sure I ain’t ever going to get a date with a $5,900+ rifle, not including scope. Damn it. Oh well, it’s still fun to look at. $2,700 for an AR pistol though? Seriously?! Not a chance, even if I had the money.
