My friend Andrew H. is building a clone of the Knight’s M110 rifle and this is the suppressor that goes with it. Size matters and in this case the Knight’s M110 is rather virile.


Here is the M110 SASS rifle.


Here it is with the suppressor atttached.



Why is the M110 suppressor so long? Here is an explanation from SilencerShop.

In addition to effective flash and sound suppression (28 dB), the M110 silencer employs an attachment method that separates the locking parts from the mounting surfaces, thus reducing pesky carbon build-up. Its consistent point-of-impact shift is maintained through repetitive lock-up of the mounting hardware during attachment.

    It’s also a reflex suppressor…

    If you want a M110 clone then obviously you can accept no substitutes: you have to get the Knights can to go with it.

    But there has been a lot of supressor development in the last few years in terms of mounts, baffle (or not) technologies, weight and length reduction, sound reduction, while staying rugged and reliable. I wonder if you built something to meet the exact same specs, could you do it with something shorter, but wider maybe?

    I guess the CSASS they were using the oss system so the answer is yes…

    It’s a reflex design, you’re only adding 10-12″ to the overall length of the rifle. It’s a trade off of weight for volume, not length.

    • Nicholas C

      Are you sure it is a reflex? Does gas expand into the areas behind the muzzle?

      • Giolli Joker

        Well, it appears to be a reflex design, having that volume available without using it would be kinda dumb.

      • Lee Attiny

        It’s definitely a reflex design. You can tell by where it threads on to the barrel back by the gas block. Typically you’d use a brake and not a flash hider like the rifle in the picture. The brake essentially becomes your first baffle diverting gases back into the space behind the muzzle.

        I keep wanting to research it further, but I get the feeling that Nick Chen here has the right idea – that the can isn’t actually a reflex suppressor and that most of the volume behind the muzzle device is “wasted” space. Look at how that portion of tube is welded on. Just four tack welds around the can, that would never keep diverted gas contained inside. The same with the locking mechanism piece, just four tacks. The rest of the can, you can clearly make out the suppressor being welded completely between each section.

        Might not be a reflex in actuality.

      Technically volume does the job, but with V = π * r^2 * h, girth give more volume for less material.

      • JSmath

        Many developers have concluded that radial length has strongly diminishing return in flash and noise reduction, which is why we don’t see as many cans >= the Liberty Goliath (2″ diameter).

        What’s just as if not more important than interior volume is considerations for flow disruption. If you weld flat washes perpendicular to the bore inside a box the same dimensions as a SiCo Osprey and left through holes twice as large as, it isn’t going to do much as a suppressor.

        • randomswede

          I think we’ll see some interesting advancements in silencer performance in the coming years with an increased interest from the military (grunt level not just we-were-never-there people), improvements in modeling software as well as “new” means of manufacture coming down in cost (5-axis CNC, “3D printing”).
          That said, I doubt we’ll ever have have a can, were using the same principles and tooling a larger version isn’t more efficient. We’ll reach a point where the added weight/cost isn’t worth the reduction however.

    Why would you build an M110 clone with a genuine KAC suppressor and all when you could just, I dunno, buy an M110?

    Last I checked they were available on the consumer market.

    • Friend

      KAC sold exactly 110 rifles that matched the M110 spec perfectly to civilians–for absurd quantities of money, on the order of 10K. There are also a few deployment kits floating around from contract overrun. Last I saw one of those it was on Armslist for a solid $15K.

      The next easiest thing would be to start with one of the special release ECRs (rebuilt Mk.11 Mod 2–USMC/Navy name for M110) turn-ins, which had the correct handguard, and change the gas block and stock out. Those can still be found on the interwebs. You’re looking at a $3300 rifle, plus a freakin’ $300 gas block, plus a freakin’ $600 stock, plus a freakin $1600 suppressor. Plus a scope I’ve literally never seen for sale before.

      Other than that, you’d have to sacrifice another model of SR25, and depending on the model you’d only be saving the receivers, internals, and maybe the barrel. All those prices up above? Still buying all of those, though new SR-25s go for $4300 these days. Used one would save you a bit of money, probably the way to go if you’re gutting the thing anyway.

      Point of this rant? If you want an actual M110 of any flavor… you’re rich.

      I’m not. 🙁 I want a Mk.11 Mod 0, personally. Ran into the same troubles.

      • Alexander Nguyen

        Why do you want this? I have thousands of dollars of KAC stuff and it is all really really crappy compared to their current competitors. I’d say get a real rifle instead. If you REALLLY must get that look just spend the $700 on an SR25 rail. Haha I know I’ve already spent more than that on their measly parts

        • Friend

          Yeah, I know man.

          It’s the same phenomena we see with dudes cloning the Mk.12… yes, I know it’s pointless but there’s something about having the rifle that dropped a whole buncha bad guys…

      • Haulin’ Oats

        Personally I’d rather have the M110A1 from HK because they don’t hate us like Knights and will readily sell us a civilian legal version of the military rifle for a more reasonable price of $5-6k usd.

      • ProudAmerican

        Interesting. Any idea what the first generation SR25’s are selling for these days? …with 24″ barrel, threaded gas block, and threaded reflex can?

  • Jtx

    6.5″ on a warm day.

    My can is bigger than your can.
