45 ACP

I have been very successful with all of my suppressor designs except one. The 45 ACP. I've tried different tube sizes all the way up to 1.500, lengths to 7.500, a ton of different baffle configurations, static and progressive spacing. You name it and I've probably tried it. The only think I haven't ...

Re: Clipping gap size??

Always clip. for 9 mm use a 3/16" ball end mill .220 deep measured from the top of the cone rim. Correct bore is .414 if you are using precision equipment and .434 if using a drill press.

Re: Choosing a route for .300blk...

I've never seen that design before, let alone how to make one of my own lol. I'm assuming it's basically a ported stack with a "second" tube over top? These are not difficult to build and should give you that coveted Hollywood quiet you seek.I would add a gas tube with a shutoff valve to ...

Re: 7075 tube

2024-T3 is another option but it is expensive. I buy mine from TW metals. 1.375 od x .125 wall is in the neighborhood of $5 per inch if you buy a 12' length.

Re: combo machines 3 in 1 lathes and mills

You won't see manual combination machines in professional shops. There's a reason. IMO, they should be avoided entirely. The only things they excel at are wasting time and causing frustration. Some folks liken them to CNC millturns. They aren't remotely close. Agree with ECCO. Run Forrest run.

Re: Advice plz: 5.56 end cap hole size, engraving location

A Chinese, Aluminum, monocore is a horrible choice, horrible. Regardless of your first go'round, don't do it. Exit bore relies on design, but stay >.080in over caliber. You can engrave whatever you want. Some do endcap, some the mount, most do the tube. Placement on tube near midle or closer to mou...

Re: Form 1 questions

Low pressure configurations should be different from high pressure configurations both in type of baffle, length and baffle spacing. You would be much happier designing two suppressors, each dedicated to the host rifle.

Re: end cap strike, 9mm threaded can

Something is way off. I'm guessing it's an alignment problem. I would order a proper size alignment rod from McMaster-Carr and check that the suppressor is in line with the rifle bore.

Re: First Form1 - .22lr

A 1" can will suppress a 22lr well, but for .223 you need a 1'5" tube with stainless steel or titanium internals.

Re: How does it look (in progress)

If you have access to a milling machine and a rotary table you might want to consider the undercut as shown in the photo. Ignore the integrated muzzle brake as this build is for a 17 hornet/hmr. You can do the cut on the lathe but when I tried plunging this deep chatter always gave me a fit. I used ...

I have a trust which Was created when I purchased my first suppressor. Since that time I now have a Class 01 FFL. I am going to be applying for five (5) form 1's in order to build five new cans. My question is should I list the truss on the paperwork or use my FFL number?
