    I currently have one in the paperwork shuffle. I am waiting on our lovely government for my tax stamp. It is a .223 suppressor that I am going to use on a 204 ruger. I know that it will dramatically reduce to sound, but I have no idea on the accuracy effect. I can not wait to see.

    Silencer Talk has several forums dedicated to building form1 suppressors. There is about a weeks worth of reading to get started. It really boils down to what machine tools and welding experience you have or have available. I have a 308 and 338 in the works and I am building a fully welded 304 stainless design 1.75 OD and 12" long.

    You may also send a PM to James Jones here. He has some knowledge of these, and in my experience is a very helpful guy.

    Get this book: Silencers, History and Development. You'll have to research the title on one of those websites that cater to those who look forward to Armageddon.

    For high velocity rounds a series of cones seems to be the best options going right now , the better comercial cans are useing some sort of cones , SRT uses stepped cones , AAC uses several varation of cones KAC is using a fluted cone.

    Their are several ways that they can be made , rather than try to explain all of them tell us what kind of equiptment you have access to , Lathe , mill? , can you weld at all?

    Its realy not brain surgery , a series of flat baffles will work well but the unit will have to be bigger to make up for the lack of effeciency of the flat baffle , their a suppressor called a Tac-16 that work well , its a 223 can but works well enough to make a 22-250 ear safe , its just some flat washers with small cones on the face to help "peel" some of the gas off

    The AAC 762SD is a great suppressor , here is an X-ray of the pre 2008 unit as you can see their ain't alot to it. This suppressor worked very well and they have since just went to a slightly more effecient cone desgine

    the new cone is said to look like this one and I think that new suppressor might have a couple more cones , this is also the same cone that the AAC Cyclone uses , its a great suppressor , very effective

    here is an X-ray of an OPs Inc suppressor and an Surefire suppressor side by side , as seen their baffle system is pretty simple just aseries of bowl shapped cones and more of them , notice that they are ported to cause irregular gass flow
    [​IMG]

    Here is a simple designe that a buddy used to make a suppressor for a 300 RUM , it worked very well , the can is apretty heavy and long but it is trying to suppress alot of gass , as you can see its simple a series of flat fender washers pressed into a cone shape and tac welded to a spacer then the whole stack was tacked together and pressed into an outer sleeve and the endcaps were welded solid to the outer tube

    My first suppressor used K baffles and it worked well but through trial and error I have found that the K baffles are heavy and not as effecient as cones for high power rifles , most of the suppressors you see with K's are pistol suppressors. Quick Silver Manufacturing uses a modified K in their all titanium suppressors and they do work but they also use a very tight bore which make the suppressor more effecient.
    the K- baffles I made came out great but they are very labor intensive to make correctly compaired to a cone

    I'll try and see wher in this waste land of a computer I have stored some pattents of several differant suppressors , to give you a better idea of who is using what.
    What type of rifle are you wanting to suppress and what are the wants and needs for your suppressor , I meen are you trying to keep is as compact and light as possible or is it going on a weapon that would be hauled very far

    hey James
    those are the photos of the k barrels that i have seen before and was planning to model. but if you have experience making cone type ones and you think they are more effcent then im all ears. would love any tips on making them to so i have some success first time. im putting one on my .308 and another on my bros .223.both guns are carried around alot since i hunt tahr and anything else with my .308. so lots of hill climbing with it here in nz.light would be key. cheers

    Theirs alot of guys that have used PVC to make some rimfire suppressors , most of the centerfire pistol and rimfire cans are aluminum and pretty thin to boot so as long as you diden't get crazy trying to trim weight then PVC should work fine.

    The trouble comes from guy trying to make a suppressor on their work bench with a hand drill and other hand tools and not being able to get the bore of the suppressor aligned with the muzzle threads thus causing bullet strikes in the suppressor and things go realy wrong from their
