Nexgen2 Defense Blowback Eliminating Silencer

Swim in the silencer pool long enough and you will eventually end up in the deep in with the AR15 shooters discussing gas regulation. There are hardliners on both sides of the debate – one team believes that a properly gassed rifle is the key to a pleasurable shooting experience. The other team believes that overpassed/undergassed situations are to be blamed on the host weapon itself, advocating buffer and spring weight modifications. Either way you look at it, the silencer plays a roll in how much gas is redirected down the barrel and gas tube toward the port and on towards the shooter (aka ‘blowback’). Nexgen2 defense is releasing the Maxflo 3D AFD silencer that is said to eliminate blowback with a specialized baffle system.

I am solidly on team ‘adjustable gas block’ to mitigate blowback and cycling issues. My thoughts focus on the fact that most rifle silencers will change the way the host AR15 operates – Either over-gassed because of the restrictions placed on the muzzle, or under gassed when running unsuppressed. Obviously, not all suppressors are created equal – baffle designs and internal volume can effect the way gas is directed in the rifle as a system.

Details and specifications are still pending, but at an MSRP of $1495 has me a bit concerned. Also, the tag lines of ‘Increased Safety’, ‘Increased Accuracy’, ‘Zero Back Pressure’, and ‘Zero Flash/No Pop’ points to some bold claims. Mostly because I don’t believe in absolutes.

In the end, independent testing on a variety of host platforms will be required to either prove or disprove the claims by Nexgen2. Other manufactures have made dramatic claims, only to find out that specialized hosts were used to achieve desirable results.

    “Engineered utilizing the most cutting edge fluid dynamics software available, with input from users in every field…”

    They got input from users in EVERY field? “What input did you get on this, tier 1 operators?” Yes. “Seal team 6?” Yes. Marines, army rangers? Engineers? Yes yes. Hunters, plinkers, gun magazine writers? Yes. Police? Sure. Audiologists?
    Yes. Lawyers . Mmmhmm. Doctors? Yes. Hot gun models. You betcha. Hollywood prop masters. You know it. Veterinarian s? Yup. Astronauts. Of course. Kindergarten teachers? Who else. Clowns? Yup!

    Yes yes yes, everyone in the world. Next question?

  • Joe

    Nothing helps disguise the suppressor’s true performance like kickass tunes. Rock On!

  • ResIpsa

    I’ve shot it. It’s for real.

    I own a bunch of SilencerCo and some Dead Air stuff for comparison, and this really does cut out the backpressure. My BCG was downright clean after running 5 mags through the rifle on full auto (10.5″ barrel).

    • Oaf

      I shot one on a S&W Sport and was very impressed by how well that can did even installed on such a terrible suppressor host.

    • BaconLovingInfidel

      What about suppression?

      • ResIpsa

        Definitely hearing safe. Not the quietest thing I’ve ever shot, but it was quiet enough.

    It would seem to me that if the gas is allowed to escape out the end by just being routed through a longer path to slow it down, then there wouldn’t be much back pressure as opposed to traditional baffles that just trap the gas in segments. I forget the name, but there was another company building one for the military that looked like and functions like a reverse jet engine. This is probably a similar principle.

    • OSS is the name of the company you are thinking of.

      They are hugely expensive. And I wouldn’t be surprised if this one is too. These designs just scream machine time. And I am not sure 3D printing technology has gotten cheap enough to do a silencer like this commercially.

      • Samuel Millwright

        We can still dream though right?

        Oh and you can’t forget jesse james & his $5000 36 torx screw asian high speed train inspired nerf football of doom!

        (If his suppressor actually did work the way it’s described that’d sure be nifty though!)

      • 🦑 🐙

        Yup, OSS. Like anything new it will take time to mature and become affordable. This may just be another step on the evolutionary ladder but it’s still exciting to follow.

  • Harbinger1117

    Handled one at the NRA show in Atlanta. HEAVY. Can’t recall exactly, but maybe 26 or 28 ounces.

  • Samuel Millwright

    LOL nick called…

    Nick who?

    Nikola Tesla, he wants his valvular conduit back!

    P.S keep the turbine though, they’re a pain in the ass anyway!

    • RocketScientist

      A Tesla-valve inspired suppressor alone wouldn’t eliminate blowback though. It would prevent the vast majority of gas that had entered the suppressor from reverting back through the barrel/gas port/chamber, but would do nothing for the gas that never made it to the suppressor. So anything making its way back into the reciever via the gas tube or chamber could still end up in your face. Similarly, a tesla valve limits backflow/blowback (ie actual movement/flow of gas) and wouldn’t necessarily reduce backpressure. Any device that inhibits the flow of gas out the muzzle is going to add backpressure to the whole system. So while this suppressor MAY contain elements of a tesla valve (ie valvular conduit) in its design (and I have no idea if it does or not), even if it did, that alone would not do a whole lot to contribute to their claims of no backpressure, no back flow, etc etc etc.

      • Samuel Millwright

        Ah yeah, i was mostly commenting on the look of certain parts very closely resembling parts of a valvular conduit and a tesla turbine….

        I have a sort of morbid fascination with both of these Tesla inventions, including obsessive compulsive hoarding of masters thesis treatments and any other technical documentation i can get WRT both…

        This culminates in a twice yearly design, build, test, analyze, and prepare for next build cycle.

        The last 3 builds and my second build for this year upcoming around Halloween have all focused on getting an internal combustion version to actually work and generate useful data…

        Do i think I’ll revolutionize the internal combustion world if i somehow wildly succeed?

        Nope, they’re just cool and i like them

        • RocketScientist

          Thats…. probably the coolest thing I’ve ever heard. I want to be your friend 🙂

          • Samuel Millwright

            Hell yes!

            I could use some help picking up the scattered remains of what used to be a robot i was using to teach myself at least a little bit about autonomous systems, machine learning, and machine vision etc at the bmx park last weekend until it had some robot existential crisis and committed suicide by charging head on at an 11 year old going the opposite direction…. Directly under the fast lil bastards tires!

            I think i traumatized the poor kid though…. I saw it spaz out and saw the kid about 2 seconds before impact and admittedly reacted poorly.

            Right as the initial crunch happened i screamed NOOOO and started running towards the now very overwhelmed child and trail of robot remains and kicked it’s broken robot body angrily muttering under my breath about how suicide is never the answer and it took the cowards way out along with assorted expletives and comments about it being a window licker and a p***y anyway!

            I really probably shouldn’t be allowed to roam unaccompanied around the general public anyway.

  • Samuel Millwright

    I won’t be satisfied until someone makes a hilsch-ranque vortex suppressor, then i can die happy… Deaf with horribly blistered hands because it won’t work… But happy!

    (Note to self if any of you bastards show up at SHOT 2018 with a working one… I hate you, i hope you know that!)

  • Hoova_cripz

      Bad spelling and grammar? 😉

          hahahahahahahaha

  • Stephen Paraski

    What is up with that music?

  • ActionPhysicalMan

    I have never had a back pressure problem with my baffled suppressor. I never even smell gas. I do use a variable gas block, a fairly low pressure cartridge, and the suppressor is much larger than it needs to be though.
    Nice writing Pete.

    • Timmah_timmah

      Now you are just talking too much sense sir! Stand down!

  • randomswede

    Not that you can tell how quiet a suppressor is from a recording but nothing says “Quiet” like rock-n-roll music track on top of the main feature.

  • Tyler

    Interesting science. But an intricate titanium machined can that’s over 20 oz. for how much? Most titanium cans on the market that can actually market themselves as being quiet are 10-14 oz and half the cost. Half the price– half the cost.. not worth the effort. I would most likely rather turn the switch to the Suppressed setting.
