Re: 5.56 build log update on pg 2

I did a form 1 can in titanium with cone baffles ( .30 cal ). Initially I was on the fence about clipping them and ended up clipping them and glad I did. BIG difference in suppression just by my ear. I have no idea if clipping a freeze plug would yield the same results but clipping does make a diffe...

I think the tone can vary using different construction materials ( tube / baffles ) as well.
I bet the guys with the spiffy instrumentation know for sure.

Re: What is the effect of making a can longer?

I have seen AR rifle length buffer tubes used as a suppressor for .22 rimfire ( no baffles) that actually worked well. It's volume did the job of containing the gas and releasing it.

Adding baffles slows and strips off heat.
There is a balance between size & effiency.

Re: What is the effect of making a can longer?

Cooling and slowing the expanding gas = suppression.
Since a longer can with more internal space (and likely baffles) the 2nd can should / will be quieter.


A recent example of this is the new line of suppressors with screw on / add on modules for added noise reduction.

Re: What's a good length for a Form 1 when you haven't designed the can?

If in doubt go big.
You can always make it shorter but not add length or parts.
Slowing and cooling the gas makes it quiet. Larger volume = controlling gas better if your baffles are not as efficient as a smaller can.
That being said I might form 1 a high volume 22 rimfire can.

I have been using these boring bars for over 25 years and I have never had any twist using their carbide bars or steel bars. Carbide will crack / break and never twist. HSS bars can bend but I have never twisted one.

Re: Buyer beware of Advanced Armament/an ongoing experience

Most companies target their market & support efforts. In the suppressor industry there are several great ones that focus on the civilian market. Now that Remmy owns AAC it does not appear the civilian is not their target market or support. I own an M4-2000 from the 'old' AAC. At the time of purchase...

Definitely hard to tell with the phone video, but the delta looks promising. Also had a chance to try any subsonic ammo? I will get a real camera and try is again and in open ground. I never had any interest in .308 subs , its why I have one of these...... http://i1329.photobucket.com/albums/w560/j...

Re: Permanently attach Titanium to Stainless ? how?

I would braze it on with 1100F-1200F solder paste. I would not braze titanium unless you have it shielded somehow...... Over 800 degrees F and titanium picks up oxygen and nitrogen contamination from the air and the contamination goes through the metal and not on the surface. TIG weld it with a goo...

Re: Permanently attach Titanium to Stainless ? how?

Permanent attachment per BATF rules blind pinning was allowed, if they have not changed the rules. If you have a titanium suppressor drill thru the mount into the barrel, press in a titanium pin then weld it closed / over it. If you have a stainless steel suppressor do the same with a stainless stee...
