Backyard Safari has a collection of images showing the AEK-919 K Submachine gun being used in training by the Vityaz (counter-terrorism Russian Ministry of Internal Affairs special forces unit).

A surprisingly aesthetically pleasing gun. The Russians tend to ignore appearances.

The AEK-191 was designed during the mid 90’s and fires the marginal 9×18mm Makarov cartridge. It takes 20 or 30 round magazines, has a 6.5″ barrel, weights 4 lbs unloaded and has a rate of fire of 900 rpm.

Many more photo here.

I blogged about the new AR57 earlier this year. The AR Five Seven is a one piece 5.7×28mm upper that attaches to a AR-15 lower and uses the 50 round FN P90 magazines. 57 Center posted a few photos of their new SBR suppressed submachine gun/PDW:

How cool is that!

UPDATE: After writing a three paragraphs about integrally suppressed firearms it turns out this is not integrally suppressed! The suppressor fits inside the handguard. I got this via. email from the 57 Center:

This particular AR57 PDW Upper in Full-Auto with 6″ Barrel, with 6.5″ Gemtech Suppressor, is currently being produced for a couple LE Agencies.

We currently have our 11″ Pistol/SBR Upper available as well as our standard 16.125″

So they are now directly competing with the full-auto FN P90. Personally, if I had a choice between this and the P90 I would go with the AR platform.

I think the pistol configuration could be a lot of fun.

UPDATE: I asked if the 6″ barrel gave adequate performance. From 57 Center:

We have excellent results with both 6″ and 11″ Pistol/SBR Barrels, this would be peoples choice, LE prefers 6″ with the 6.5″ Suppressor, this unit also works in Sub Sonic,

It is very impressive that the action can cycle subsonic rounds (a light 30-50 grain 5.7mm bullet traveling below the speed of round is comparable to a 40 grain .22 LR Standard subsonic round).

Andy has photos of the destruction at the recent AAC Silencer Shoot.

Lots more here.

Andy @ AAC has posted scans of a Maxim Silencer brochure. The prices range from $5 for a .22 suppressor to $9.50 for a high powered rifle caliber suppressor.

What is cooler than a .50 BMG? A suppressed .50 BMG

The Cyclops Suppressor

I spotted this rifle over at longrangehunting.com. Is it anti-air artillery or a deer rifle?

Built by a New Zealander … they sure know how to build a cool rifle.

Beautiful scenery

The rifle has a custom suppressor with a muzzle break! Here is a close up:

I assume the “404″ refers to the 404 Jeffries.

my suppressed 7mm/404 which weighs 20 pounds all up, and pushes a 180 grain Berger at 3350 fps.

Wodger Wabit over at RFC machined a suppressor adapter for a Volquartsen carbon-fibre wrapped barrel threaded for a .22 muzzle break so that both can be used. Neither the suppressor nor the muzzle break need to be modified. Very cool.

The muzzle break and the threaded barrel

Threaded barrel with adapter


Adapter screwed in, ready for the suppressor.

UPDATE:

The creator of the adapter, Roger, just sent me an email. Check out his website. It contains lots of interesting information on suppressors and air gun hunting.

Silencer Research has posted an impressive comparison of 19 different .22lr suppressors.

These tests were conducted on January 5, 2008 using 19 silencers from various manufacturers around the country. Some of the best silencers in the world were measured in this test. The test was fired using the Walther P22 pistol and a bolt action rifle manufactured in Russia call the Tula Toz 78. This is the preliminary release of this data and more individual reviews will become available as time permits.

Unfortunately, they require you to register (for free) to view the info and the videos are normal windows video files, not hosted on youtube type sites. They really need to get into this blogging ‘thing’.

What is interesting is that the second best suppressor, with regards to noise reduction, costs $295.00 while the worst costs $595.00! I have always said I do not trust these ‘high tech’ expensive suppressors.

How far would you go to enjoy 12 gauge shot gunning without disturbing the neighbors?

Wendell Diller has invented a lightweight shotgun barrel extension that is about 5 feet long!

When Sean Coffey’s honker call pulled a flock of geese within range, paraplegic Dave Guzzi swung his shotgun with a 7-foot-long barrel and dropped one of the geese dead.

There was a moment of stunned silence — and not after the goose tumbled out of sky. The morning stillness was barely disturbed when Guzzi pulled the trigger on his extraordinarily long shotgun.

The sharp blast of the 12-gauge was replaced by a muffled fzzzttt. Sitting just four feet away, I was struck by how the shotgun sounded like a loud air rifle. Guzzi, who lives in Burnsville, laid the experimental shotgun between his legs and waited for more geese.

“Pretty amazing, isn’t it?” he said of his gun.

Apparently it is also useful for deer hunting.

This video from SHOT Show 2007 shows Advanced Armament’s new suppressors. Including a quick release suppressor designed for the SCAR-L, the quietest .45 pistol suppressor (or so they claim), a new AR-15 and .22 suppressor.

From B.B. Pelletier:

a class three dealer examined it and said in his opinion it could not be removed and attached to a firearm with success.

Gamo has taken pains to make the outer case tapered front-to-rear, plus they have molded two huge flutes into the side of the case. They’ve also made holes in the flutes that expose the sides of the baffles, which are a soft synthetic material, to the air.

It was his opinion that the silencer would be too difficult to remove from the rifle without destroying it, and, even if it could be removed, that the baffles would blow out the sides if exposed to even the low pressure from a .22 rimfire cartridge. In other words, it wouldn’t silence a firearm for even one shot.

B.B. Pelletier reviews the Gamo Whisper, Gamo’s suppressed air rifle which I blogged about recently.

Noise is what the new Gamo Whisper is all about, and I’ll address that issue for you right now. I don’t find the Whisper to be that much quieter than any other spring piston air rifle of comparable power. In fact, my tuned .22-caliber Beeman R1, which has no silencer, is quieter because its powerplant makes less noise. The powerplant is where the bulk of the noise of a spring gun comes from, not the discharge at the muzzle.

This article has a great comparison between wet and dry suppressors. It also includes some great videos.

The term ‘wet’ means some sort of liquid, be it oil, water, grease, gel or another substance is used to cool the gasses exiting the suppressor. The gas leaving muzzle or suppressor is what causes most of the noise.

From wikipedia.org:

“Wet” suppressors or “wet cans” use a small quantity of water, oil, grease or water-based wire-pulling lubricant in the expansion chambers to cool the propellant gases and reduce their volume (See ideal gas law). The coolant lasts only a few shots before it must be replenished, but while it lasts it can greatly increase the effectiveness of the suppressor. One manufacturer claims a 30% improvement in sound suppression for “four magazines” (32 to 68 rounds) with the addition of 5 ml (one teaspoon) of water or light oil to their suppressor.

I am a big fan of suppressors and own two. I have a .22LR and a .22 Hornet suppressor. My hornet suppressor can also be used on a .22LR or .22 Magnum (WMR).

In the near future I am going give ultrasound gel a try and see how it works.
