Re: Where to get nomex cloth?

https://www.riflesonly.com/pro-shop/tactical-gear/tab-sas-suppressor-anti-mirage-shield.html I understand the draw of a handmade suppressor and a self made cover to complete it. For everyone too lazy to sew- like me. Custom made sizes for $65- can withstand 1800 F. I have one on my .308 and it works...

Re: New design- The "Isobaric Baffle" Monocore ***UPDATED 5/

Thank you for the compliments. I do not think that doing a helical spiral would reduce noise, but it would look cool! The backporting I added would be affected and with the currently config the baffles pull the blast evenly off the bullet. Must be nice living in a suburban environment that allows th...

I see your logic, but I can't believe that it is that easy. I am not willing to put forth any more effort researching it, so I will drop it and concede. So why doesn't everyone post pics of their unregistered firearms? I would love to see the workmanship and variety. I would gladly post pics of my f...

Re: form 1 and receivers

I think you gave some misinformation. You need a form 1 to make a firearm, sbs, sbr, or silencer. You cannot make a firearm yourself without a form 1, it doesnt matter if it js a class 3 or not. A form 1 allows a creation OR change to a class 3. You can make a upper receiver, but that is not a fire...

I have a Arsenal SLR-107 UR (7.62) that I Just got my form 1 back on. The 14mm threads I have been told - will not be concentric. So I figured adding a perfectly concentric adapter won't help. I deceided to shorten the front sight post just before the threads and thread the actual barrel. This will ...

Re: Designing an Automatic Shotgun: Need expert help.

The advantage is fun! Also, if there were a riot situation, I can see where buckshot from a FA shotgun would make an impression. +1 contact Tony at Tromix - He could help with a application. His are AK based Saiga 12s. He created an evil looking "shark brake" that works well combating ris...

I also have tried to hypothosize what heat will be generated by this design. Most of what I have heard here is that sound energy is converted to heat energy- energy is only converted, not eliminated. But other places have stated that out of phase sound is sent to the ultrasonic spectrum, not capture...

So what happens of the tube gets a little loose and you try to unscrew the suppressor from host? Will the tube just spin around the monocore or will you have some kind of tool to remove?

I'm not sure how the oval cuts at the blast chamber end would be made without a mill. Maybe he's concerned about indexing precisely 90 degrees? The cuts are all square angle cuts, but on a round surface so they look oval. It needs to be drilled at 90 deg angles and I didn't know if I could do it on...

This also means and all the forward push of the baffle stack is put onto the end cap threads, I forgot to mention there are no actual endcaps, the monocore is made to thread into and be the bullet exit from, this means variables are limited to the bore straightness, the thread on the suppressor and...
