Anyone know of a good source for threading a piece 1/2x28? It will begin as a thread protector and may become an endcap later.

Looking at the Sig site:

SIG MPX-C - NFA Rules Apply
Carbine Variant - 6.5' barrel with 9.5" muzzle brake permanently attached - Semi-auto
Extended carbon fiber adaptable handguard
SIG MPX reflex sight included

That may settle it.

With the ATF considering this a muzzle brake, do you think we will see manufacturers introduce "muzzle brakes" similar to this design? Or will the ATF reconsider what a "muzzle brake" is?

Why are some suppressors rated full auto for smaller calibers and s/a for larger? Like the sparrow - f/a okay for .22lr, s/a only for 5.7. Is it the pressures produced, the heat generated or something else?

What has been your experiences with Onlinemetals.com as far as quality of cuts they may have done for you, actual dimensions of the products, and general service provided? The metal I have bought from them has been fine. Their prices are high. What other reasonably priced vendors should I consider?

What is the thickness measurement of the baffles?

Anyone ever use these for threading tubes and end caps? How well do you think they'd work?

Lame.

No he didn't. He states "I used 5 k baffle like this:". Lighten up.

How difficult are these to machine and weld?

Bigger is better, but look at what can be done with a mini lathe:

Uh, thanks for the bump, but I'm not tracking. And I don't play golf.

Is 4130 steel gtg for baffles/tubing for 5.56? How's the machinability and corrosion resistance for suppressor use? Thanks.

Did some final steps cleaned up the end and bead blasted it. Ready to be coated! shot it a few more times and it is holding up well. Here it is next to my AAC M-2000 http://i1019.photobucket.com/albums/af311/jimmym40a3/12.jpg http://i1019.photobucket.com/albums/af311/jimmym40a3/10.jpg Simply awesom...

Looks like that works out to 1.377 inches. 1.5 X .065 4130 tubing has a nominal ID measurement of 1.370. Would be a press fit but it might work. I have not priced ss freeze plugs but that seems kinda high. I bought a box of 10 regular high wall plugs for about 6 bucks from my local parts store. Wer...

Would these be good in a freeze plug suppressor?

M or K baffles for 5.56? What say y'all?

Double tap.

Where did you get this? I built a thread-on F1 5.56mm suppressor that uses a Jet brake/mount. It was easier to buy this than make it, cost me about $90 and came with a collar to protect the threads when the cans not on the gun.. Threads on I.D. are 1/2-28 for .223, but they make 5/8" thread for...

Very nice!

Uh, yeah, I'm not tracking.

Out of curiosity, can the 3 lugs not handle the 5.56 pressures, or are you saying a 9mm suppressor can't handle it? BTW, my intention is not to fire 5.56 through a 9mm suppressor.

Does anyone know if this will thread on to a standard AR threaded barrel?

Can you list multiple calibers on form 1?

Is aluminum okay to use for monocores or baffles up to .45 caliber? If not, at what caliber is it best to start using steel? Thanks in advance.
