No , I have not forgotten about MAE , I think for the money you cannot beat them , $230 for my muzzle 308 SS MAE( 100% SS )I have 2 308 ones and 1 22mag ( for a 22 hornet ) .
They are 1/4 of the price of say a BT can , the BT can is twice the weight & has better sound reduction , so different niches .
I do wish MAE would maybe make a version that mounts onto a brake , like AAC , & put a few more baffles in the muzzle forward cans , even if thats going to make the can a wee bit longer .

Looking at a least a few more MAE cans soon.

Later  Chris

Hi ODL ,

Have you any pics that you can release on the 308 QD cans that go over a brake ?
I may have to buy one .

Later  Chris

I will get a video of the QD prototype cleaned up and post a link as soon as I have it.

Regarding the materials and manufacturing methodology:  The material used is 90% titanium, 6% aluminium and 4% vanadium also known as Ti-6-4 Grade 5 Titanium. The method is actually Selective Laser Melting although it was originally called "Laser Sintering".  Having been exposed to sintered materials in the 80's, I almost gave this technology a pass as the old sintering created a type of cast part. 

The way parts are created now is far different and has no resemblance to the old sintered methods at all.  The as built strength from the plate is around 1000 UTS and 900 yield.  After parts are tapped and any hand clean up, they go back into the oven for stress relief, heat treat and nitriding.  At that point, the UTS is around 1200 MPA and yield is around 1000 MPA.  The nitriding also provides a hard surface both inside and out that ranges from 62 Rock C at the surface gradually dropping to 36 Rock C by 28 microns deep.  This is advantageous for baffle longevity.

This method of manufacture provides the only true solid suppressor construction since all the material is fused to the entire structure in one monolithic part.  This allows for thinning out some areas and thickening others as needed locally.  Many manufacturers emulate this by fully welding the baffle stack together and then welding the ends on.

Most of our cans are designed for semi auto fire.  The can I sent to Canada for sound testing was also tested using burst fire for 200 rounds.  I have the can on my desk and the finish still looks new!  It did get some erosion since the blast plate was too far aft for FA but I was not aware this test would be run although it is handy that it was.

I have one can that is built for limited full auto and is currently being tested by an overseas group.  The testing regime is 1000 rounds while testing for POA - POI shift with 3 removals and re installs, group deviation with and without suppressor, normal fire and three times in the test a rapid fire stress test is performed with 20 rounds fast semi followed by 20 rounds burst followed by 30 rounds full auto.  The can is very hot at this stage. 

This is the SBR can that is out of stock on our site.  It is available for special order or if it is popular enough I will stock them.  I made one up in 15-5PH stainless as well but the titanium model was preferred by the testing group.

If you look at the late 80s , the US Navy , put out a request , for a suppressor for 308/300WM rifles , where the cost & weight where not to be main factors , the main factor was maximum sound suppression ...

the cans where large & long , 1.65 inches in dia & 17.24 inches long , out of 100%  304SS , weighed 1.66kg ( 58.5 ozs ) .

Using 308 std ammo , it reduced the signuture by 32 dB ( A ) , & with subsonic by 34 dB ( A ) , same for 300WM , but peak sound held longer .


Bean counters put out RFP's where weight and size is not an issue but real people have to hump that gear all around creation.  Today, there are many cans that are doing as well as that custom built monstrosity that weighs a kilo and a half that are half the length and weight.

I plan on getting a bolt can down to the mid 130's with standard ammo and will try my best to get a decent size AR10 can to 138 at the muzzle and ear with a 20" barrel.  Should know next week.

went out wobbly shooting this weekend. fired 30-40 shots from 7.62x39mm and mate fired 30ish from .308 mine has a spartan on it and his is also a gunworks overbarrel..looks similar but has fatter mid section and more knurling. both sounded about the same and sure were pleasing to be around..no more ringing ears and shooting close to each other but at different heights on a ridge knob ment better area covered without deafening each other. didnt really realise just how good this would be but sure are stoked now.

I have 2 rifles Browning a bolts in 270 available at the moment. Mine has an original highcountry sport suppressor over barrel which I bought in 2002. Weighs 750grams!! Is very quiet and reduces a ton of recoil. The other rifle has a hardy like the one shown in this forum. It is way lighter but noticeably louder than the highcountry sport one. Sonic also do a suppressor similar to the DPT. Have put one on my AR and are very light and compact.

The other thing to consider when using a suppressor is using subsonic rounds as this would help reduce the noise even more.  I am looking at putting a suppressor on my 308 but none of the info on here so far is helping me decide which one to get.
I had been told ZIGGLIANI suppressors are the way forward.  Does anybody have one and can tell me how they perform Smiley

using GW spartan a subsonic round from 7.62x39mm is quieter...or seems to be than .22 through moderator......twice Ive shot rabbit at 10-15 yards and its mate hasnt moved till I tried to operate bolt to reload. Wink

Aw... got all excited these fore a minute when I read you were aiming to get a bolt gun suppressor down to 130... but I think you mean the sound signature down to 130 db... I want the weight down to 130g!

We nailed a fat stag late last nite with our Tok Can. The first shot took a whisker of fur off the top of the neck. The stag put his head up wondering what the commotion was and then got one just a smidgen lower. Sure the lack of noise was a great advantage.Lovely seeing all the action via Swaro EL's.
