I'm an engineer specifically in Silencers and I do this for a living, daily. I'm 100% certain of my answer. I literally have tested bullet destabilization, tested porting barrels and their effect, tested velocity changes with barrel length, phantom high speed camera testing, etc. Zero disinformatio...

Be careful when porting. This isn't usually a home hobby job. Best practice would be to cut and crown you barrel to desired length (3.75" if you desire) then thread that to 1/2-28. Then add a barrel extension to legal rifle length and pin and weld. The barrel extension will have a bore diamete...

The Wolf baffle is not eccentric and can be reproduced using a dremel tool. This baffle is easy to make and in retrospect can be made without a welder. Don't overthink the eccentric tube its easy and if you need advice you are on the right page.

Eccentrics need not be complicated only the end caps need to to be off set and timed the core remains in line with the barrel . The core you have chosen needs some improvements as the gas disruption will be low. A good choice would be the Wolf suppressor H&K used in the MP5SD. You may need a wel...

You know the swarf gods need their sacrifice.

I can't think of single reason not to continue with 17-4

I have never suppressed a .410 but would love to do so being a fan. If you ever wish to build another in any gauge I would love to contribute to the design. A automatic or a recoil operated host would make speed control a bit easier and a eccentric would be very very cool. Keep up the fine work, loo...

You are a very patient man and may be overqualified for this work. Have you ever packed it or ran it wet.

A suppressor 1.375 x 9.00 filled with clipped cones will do the trick. You can base port the cones to reduce back pressure. Welding is the way to go as it saves weight ,with no spacers needed. Other than the blast baffle all materials mentioned allows for thin baffles. Unless its FA a Ti can and baf...

The heat of a SBR is truly intense and ...

what effect does baffle spacing have on higher port pressures? Closer spacing raises port pressure. Previous ports allow more gas pressure on the next port inline. Wide spacing lowers downstream pressures due to cooling and expansion. Think about this : normal practice is ported cone baffles with a...

Its often asked if ports should be aligned. Yes ported cone and K baffle should. The reason is asymmetric port flow reinforcement in a reducing pressure environment. Each baffle in turn strips high pressure gas where the port or clip allows a stream of gas to move forward adding to higher pressure p...

I have never made a investment in the finer details of the Nielsen but can make a working model. First keep in mind the bullet has left the suppressor before the suppressor body is pushed away from the pistol. The piston keeps the suppressor body centered having contact points front and rear. The pi...

Matt that is a very nice can and I congratulate you. A+

Don't forget to feed the trolls on a snow day for the feds.

45 acp 410 grain @ ~ 750fps out of a 5-inch barrel. That will put some swing in your dingaling. There are powder burn differences between rifle vs pistol power and you will have to deal with a higher volume powder in the short .45 acp suppressor plus possible threading issues, but it might work wel...

Its a suppressor mounting system using 1.375x24 as a standard. I like the idea!

To the OP: I know you have some concerns about a baffle being damaged ,however this almost never happens. I started building back in 82 and in all that time I had one major fail. A knucklehead used a uber light experimental suppressor on a belt fed machine-gun. After nearly a full belt It suffered f...

Weld this up!
I get the finger-bang of mechanical take apart things but in the end its a dirty muffler.

I want to build a reflex can like a OPS Inc that is on the Mk12 mod 0 I also want to be able to use it on my SBR with a 12" barrel. To do that i would have 2 seperate endcaps to mount the can. Would the endcap be considered another suppressor. You can't have multiple end caps but you can have ...

I would start with the smallest size until you reach your desired speed. Nobody can give you an exact size as chambers very as do barrels. The old saying of the devil is in the details apply. Make sure you do not cut into the chamber or the lands center it in the throat.

I want to port a .22 LR barrel to keep high velocity .22LR rounds subsonic. I understand the "it will ruin your gun" "don't do it". Just looking for some good advice. I do not have access to an EDM but I do have access to milling machines. Has anyone here tried porting before? H...

I am amazed at the lack of concentricity of the bore to the exterior or the barrel.

Well what did you do. For a integral turning barrel on center is a option.

Not true integral since the barrel won't be ported. But the tube will mimic the look of a bull barrel. Anyway, I'm mounting the receiver and barrel in a Viper fixture so I can thread the barrel. I keep fighting myself mixing up inboard and outboard screws while adjusting. Just taking a break and ha...

Reproduction of a historic piece should be accurate down to the metals used. A modern replacement would be a different matter for another post. !
