Integrally Suppressed YHM 10/22 Barrel

YHM, or Yankee Hill Machine, has been a long time (if under the radar) company manufacturing suppressors. They manufacture a bevvy of options, across handguns, rifles, and rimfire. Of particular interest (at least to myself) is their integrally suppressed 10/22 barrel.

At first glance, the barrel is only a 18″ long .920″ bull barrel, but hidden inside the last 8″ or so is a monocore baffle stack. The suppressor is threaded into the barrel via a hex adapter for easy insertion, removal and cleaning.

Unlike other integrally suppressed 10/22 barrels, the YHM does not port the barrel early to reduce pressure and slow supersonic loads to keep them subsonic. As such, its up to the shooter to determine which ammunition to use.

At 18″ with the outside barrel sleeve, having this barrel would make a 10/22 or derivative firearm only a single-stamp gun instead of the common practice of having to SBR a standard receiver and then get a second stamp for the suppressor. While it does remove some versatility from the weapon system, it does work well.

Vigilant Spectre Operations (VSO) got their hands on one courtesy of their relationship with Silencer Shop and put one through its paces on a 10/22 receiver.

    F-ing cool. Nothing else to say about this one. Many feels, much want.

  • JumpIf NotZero

    I have no doubt Gemtech’s Mist (terrible barrel name) does better with 2″ less length.

    18″ integral? YHM’s patented medicore core? Come on.

    Sounds loud.

      Action & ejection port noise, I think. That’s why integrals seem like a waste to me on the 10/22. It’s stupid quiet with any decent muzzle can, those can be very short, and much more versatile.

      As for the SBR question, tac-sol solved that with their perm – attached barrel shroud barrels.

      • TheNotoriousIUD

        Agreed, there are much quieter screw on cans and I dont need an SBR 10/22.

        • JSmath

          Well, the point of the integrally suppressed barrel is that you don’t need to SBR it either.

          Some designs for integrally suppressed 10/22’s and the like have more porting to bleed off pressure upstream and keep most ammo around the subsonic velocity. This one apparently doesn’t, though.

          • Budogunner

            Google the Tac-sol SB-X barrel for the 10/22. SBR length with muzzle suppressor, but only one stamp.

            They even make a version for the takedown variant now.

          • JSmath

            I’m familiar, my 22LR/rimfire can is a Tac-sol. 🙂

            The SB-X doesn’t work for me. The fear of getting an adapter stuck down in the shroud or somehow damage the threads (Murphy’s law), that’d be the end of that fun for me. So, out of spite or anticipation, one might say “then just leave the can on”, to which I say – then it’s no different than an integrally suppressed barrel, other than that some of those (not the SB-X) are designed for maximum convenience.

            Some suppressor designers have thought of this problem as recessed silencers got trendy. There are a few on the market that have end caps that could be loosened or removed from a shrouded barrel with a long tool. I wish all manufacturers did this.

            I don’t have an SBR yet, but the platform that I plan to register is an AR-15 with a two piece, free-floating hand guard that may be removed without messing with the barrel nut. Once I get the paperwork approved and have the barrel cut down I won’t have to worry about stuck end caps.

    Do want!

    Comeooooon hearing protection act.

      That is the only way I would find this commercially viable, sadly.

    • The problem with that is it would make these illegal in many states that they are legal with as NFA items.

  • Tizwicky2009

    Kind of loud….

      It could be the ammo they are shooting.
