Thompson Machine’s Modular .22LR Suppressor – The Horizon

When it comes to current silencer trends, modular is king. And for good reason – with all of the ridiculous restrictions placed on the making, transferring, owning and possessing of National Firearms Act (NFA) items like silencers in the United States, the ability to run one Silencer in multiple configurations is huge. Building on this theme, silencer manufacturer Thompson Machine has just released the Horizon 22 rimfire can.

The Horizon is obviously sold as one unit, but can be configured in dozens of different lengths by using a combination of screw-together baffles. With four “long” baffles and six short baffles, the rimfire suppressor can be optimized for length or overall performance.

Manufactured from Titanium and Aluminum, the Horizon weighs in at only four ounces when assembled in the longest configuration. Obviously, again due to stupid outdated NFA laws, even though the Horizon is like grown-up Legos, only one silencer can be assembled at a time.

Personally, I love it. Manufacturers like Thompson Machine are pouring time and money into R&D, despite the alleged market downturn and heavy regulation. I can’t wait to try the Horizon.

Thompson Machine Modular Horizon 22:

(Major points for the ode to the HK-backward-bullet snafu.)

From Brooks at TM:

It is called the Horizon .22. It is totally modular, and can be configured in anywhere from 1.25″ to 6.85″ in length. It has two sizes of baffle (all are interchangable) so that you can custom tune it to your particular host gun. (I.E. My favorite configuration on a 16″ .22LR rifle is six short baffles which yields 4.25″ in length. My favorite on a .22LR pistol is 4 long baffles and 3 short baffles which yields 5.25″ in length).

In the 6.85″ configuration, it is the quietest production .22LR silencer I have ever heard on both pistol and rifle hosts. It weighs under 4oz in its full configuration and materials are Grade 5 Titanium and 7075 T6 Aluminum. MSRP is probably going to be right around $449.

  • alex waits

    Like the q erector. Cool.

  • gerald brennan

    In a few years (barring fed stupidity) suppressors will cost less than $100. I don’t want to wait, so I will have to help some company make a tidy profit and recoup its R&D instead of waiting to take advantage of new processes and materials (I’m looking at you 3-D Printing) and economies of scale. I’m not complaining. I’m just sayin’.

    • iksnilol

      No, they’ll never be under 100.

      • RocketScientist

        Thats just like your opinion, man.

      • Risky

        A ‘good’ suppressor may never been under $100, but when the market opens up to the masses there will be TONS of competition of on the low end of the market. There’s nothing about making a metal tube with some wire mesh as a baffle that will cost more than $20 to be mass produced with today’s machines.

        • iksnilol

          Might as well stab an A2 flash suppressor through a can of bud lite at that point. Wire mesh, for chrissakes, we’re civilized.

      • BryanS

        Depends on how they are de-regulated. If de-regulated like the SHUSH act calls for, then its just another accessory. If like the other acts, then it is still a firearm, and has all the regulatory baggage that comes with, including cost.

        Unless we are talking 80% kits…

  • SGT Fish

    more threads to come loose! yay!

    • iksnilol

      If you’re stupid and never tighten them, yes.

      Alternatively,if they’re stupid enough to use right hand threads, then yes.

  • maddog

    will it work for 223 with a thread adapter.

    • Steve Truffer

      Once. Aluminum is utterly insufficient for addressing the muzzle blast of a .223

      • Lee Attiny

        You’d be surprised

  • Cymond

    This is really cool. They’ve taken the concept of the Rebel SOS-22 to a logical conclusion. Just don’t run it recessed!

  • jamezb

    $449? Well heck, that’s a lot of suppressor for under $500!

  • Blake

    God didn’t they even try to cut the threads so the designs would line up in every section? Looks like crap.

    • Cost increase for no functionality. TANSTAAFL.

      • Ben

        Their cans can’t afford to lose much more functionality. They are already very lacking.

  • Big.Little.Kid

    This looks a lot better than the Q Erector IMO. I might have to own one if it performs as well as they claim.

  • Ben

    I won’t get burned by Thompson machine’s sub par, overpriced products twice. Fool me once…

  • B-Sabre

    With four “long” baffles and six short baffles, the rimfire suppressor can be optimized for length or overall performance.

    1. That’s what she said.
    2. So to speak.

  • Mrninjatoes

    That is nice! I love the sexy beach shot.
