Ja minä kun luulin, että jo WW2:n aikoihin oli revolvereja jotka oli tarpeeksi tiiviitä vaimentimien käyttöön.

Hyper-X 9mm

Winchester has a new label of ammunition to catch the wave of silencer popularity. It is called Super Suppressed and it is tailored to make your suppressor experience more fun than ever. It is going to be initially offered in 6 calibers with the potential for more to come.

All of the calibers being offered are loaded to sub-sonic velocities to keep the noise down, but are still going to provide consistent accuracy. Although obviously engineered and geared for silencer use, this ammo will still run reliably through non-suppressed firearms as well.

The calibers that will be available for consumers are as follows:

  • .300 Blackout | 200 Grain | 1,060 FPS | SUP300BLK
  • .308 Win | 168 – 180 Grain | 1,060 FPS | SUP308
  • 9mm Luger | 147 Grain | 990 FPS | SUP9
  • .45 Auto | 230 Grain | 835 FPS | SUP45
  • .22 LR | 45 Grain | 1,060 FPS | SUP22LR
  • .22 WMR | 45 Grain | 1,060 FPS | SUP22M
At the moment, there are no advertised MSRPs for this new line of Super Suppressed ammunition. Hopefully within the coming weeks after SHOT Show that information should become available to all of us.

A second line of ammo that Winchester will be introducing in 2018 is their Hybrid-X. The Hybrid-X bullet is unique because it has a 85% blend of copper and polymer with a purely polymer tip. It also boasts a jacketed segmented lead core that in Winchester’s words is… “programmed to deliver massive energy transfer through consistent core fragmentation.” The picture below is a perfect visual for what this would look like.

As DefenseReview (DR) alluded to in our previous piece on the Joe Firearms AJAK Enhanced Combat/Tactical AK’s, there’s a new zero-back-pressure-suppressor game in town called NexGen2 Defense, or NG2 Defense for short, and they’re creating a lot of interest and excitement with their NG2 MAXFLO 3D AFD (Advanced Flow Dynamics rifle cans (silencers/sound suppressors) in both 5.56MM NATO (5.56x45mm NATO)/.223 Rem. and 7.62mm NATO (7.62x51mm NATO)/.308 Win., and DR got chance to see how the technology works at SHOT Show 2018. As you can see in DR’s video below, company founder/designer/inventor Ernie Bray was kind enough to show us a cutaway version of one of his suppressors, and explain its tech to us in considerable depth–but the main points are that NG2 has full-auto-rated zero-back-pressure cans that can be quickly popped onto your rifle, carbine or SBR (Short Barreled Rifle), and then popped right back off again. Pretty cool.

DR’s actually no stranger to zero-back-pressure suppressors. We’ve been covering OSS Suppressors for awhile, even back when they were known as Bravo 18. The latest Helix QD OSS cans look pretty great, but then again, so do the NG2 cans. Who’s are superior? DR doesn’t know yet. We’d have to see how both perform in military testing in adverse combat-type conditions at high-round-count in both full-auto and semi-auto fire. In the meantime, Defense Review will just let Mr. Bray take our readers through the NG2 MAXFLO 3D AFD Suppression tech and capabilities in our video below.

DefenseReview’s (DR) found that it’s often the little things that can make your life a lot better and/or easier. Assuming it works as advertised, the Magpul Suppressor Cover – 5.5″ (5.5 inches) is one of those products. When it comes to guns heat’s the enemy in a whole bunch of ways, particularly with rifle/carbines, and even more particularly with select-fire rifle/carbines, including those in 5.56mm NATO (5.56x45mm NATO) caliber.

Anyway, the Magpul Suppressor Cover – 5.5″ (5.5 inches) is specifically designed to cover 1.5” outer diameter/5.5″-long round cans (silencers/sound suppressors) like the popular Surefire SOCOM556-RC2 muzzle can (silencer/sound suppressor), and it would appear to be very well designed for that purpose

The Magpul Suppressor Cover – 5.5″ consists of a “heat-resistant polymer sleeve overlaid onto a raised stainless steel heat shield that mounts directly to the suppressor body with steel clamps” that “minimizes heat transfer to keep external cover temperatures up to 1000 degrees F cooler than the surface of the suppressor and allows cooling airflow across the can. Additionally, it serves as an enhanced thermal insulator and signature reduction device, significantly mitigating mirage distortions to the shooter’s sight picture, reducing the likelihood of impact damage to the suppressor body, and lessening the chance of accidental heat-related injury or damage to personnel or equipment during weapon firing and cool down.”

Tuota olisi hauska kokeilla, minkähän verran tuo tekee ennestään etupainoiseen vaimennettuun aseeseen lisää massaa ja peittääkö kasvanut halkaisija jo näkymää minkä verran? En usko että tuo tolkuttomasti bloggaa näkökenttää mutta painosta ehkä olisin jo vähän huolissani (itsellä 18" heavy barrel AR jossa teräskannu nokalla, siinä sen lisäpainon jo huomaa ja en ainakaan itse olisi halukas siinä konfiguraatiossa ottamaan grammaakaan piippupäähän lisää massaa.)

Jos vedät hupun siihen kannun päälle niin melkein saman verran kasvaa halkaisia. Painoa on kuitenkin paljon vähemmän kuin tuolla polymeerisuojalla. Rautaosiahan siinä ei ole muuta kuin nuo kiinnittimet.

No niin, tuohan näyttää tuolleen kuvattuna ihan fiksun kokoiselta ja painokin polymeerisenä hallussa.

Sellainen tuli vielä mieleen kun joissain vaimentimissa on noi sivureijät (ainakin Saimaa Still:ssä) joista puhaltaa pihalle että aiheuttaako tuo haasteita käytölle vai onko siellä sen verran ilmarakoa välissä ettei mitään väliä?

Tuli sellainen "haluan" efekti jos ei mokoma kapistus maksa ihan mansikoita kun vähänkään vauhdikkaamman treenin jälkeen saa aina odotella että vaimennin jäähtyy sen verran että uskaltaa laittaa pussiin.

Näyttäisi tuossa muutama milli rakoakin olla mutta onko se riittävästi vai ei, niin siitä einole hajuakaan. :oops:

Mahtaisiko Saimaa Stilliä olla mahdollisuuksia max flow vaimentimen tekoon?

Enemmän ne kuumottavat perinteisessä. Max flowssa kuten OSSn kannuissa kuumat pakokaasut pääsevät ulos, eikä ne jää pyörimään kannun sisälle.

Tässä Macin arviot OSSn uudesta max flow kannusta.

OSS loaned TFB four suppressor models for testing: The HXQD 556k, HXQD 556, HXQD 762 and the HXQD .338 Magnum Ti. We looked at some of the specifications and details last time, but additional information can be found on the OSS website. They also loaned us an awesome “battle rifle“ host: the H&K CSASS rifle chambered in 7.62X51.
https://www.thefirearmblog.com/blog/2018/09/01/oss-suppressors/

Overall, in my limited testing, all of the OSS models performed very well, especially at the shooter’s ear test location. Even the short 556K, while showing the loudest numbers of the bunch at the muzzle, had respectable numbers for the at-the-ear location.

The “equilibrium point” seems to be the 556 model on the 16” barrel, where MILSTD muzzle and at-the-ear numbers were very close to each other. Also interesting was the fact that the extra volume of the 762 model did not provide much additional suppression over the smaller 556 model.

And the 762 model held its own against the Magnum Ti model, even sometimes out performing the longer silencer. But at-the-ear performance between the two silencers on the CSASS rifle was negligible.

The latest generation of OSS Suppressors appear to be real performers that provide excellent suppression at the shooter’s ear. The weight of the silencer as well as the muzzle device is a bit higher than I’d like to see, but in the end, the suppression levels from the Helix series are worth of a hard look if you are in the market for a rifle suppressor.

Gone are the days of what I perceived as gimmicky, over complicated hexagon sleeves and two part systems. I am impressed.
