Does a suppressor count towards the barrel length?

[USMC_0311]

New to Class III, just purchased my first suppressor. Does a suppressor count towards the barrel length?

Only if permanently attached; i.e. pinned and welded to the barrel.

which IMHO is usually a bad idea.

Good to know, now time to start working on the SBR!

either do the brace thing, or SBR. I think form 1s are still online and quick these days

My eForm 1 SBR stamp was approved in like 28 days around February. The engraving cost me about $70 at Cooper Custom but IMO it was worth it, barely noticeable.

Research pretty carefully before you stick that can on an SBR.

Another option to avoid the SBR route is to permanently affix a "shroud" to the end of the barrel that will give you an overall length that makes it non-SBR. I don't remember where I saw it but it was a slick setup. Say you have a 12" barrel. Make the shroud 4 1/4". If your can is 6" that would give you enough room to screw it on. Yes, it would be some custom work and you'd have to decide if it's worth it but it an option.

Let me see if I can fine the article.

Something like this. (I know this is a pistol. This is just so you get an idea)

What are you referring to here? Pressures?

What are you referring to here? Pressures?

+ heat and erosion

Obviously varies with suppressor design/materials, caliber and barrel length.

This.

The shorter the barrel, the faster the blast baffle will erode/wear out. Not all suppressors are created equal. Some are rated for SBRs down to a certain length, some don't have a min. length rating, etc etc.

I have never heard this before. Reference please?

I couldn't find the article. It wasn't done on an AR. I "think" it was on a CZ scorpion or Sig of the same type build.

My thinking for an AR (again, purely concept here) would be to thread the barrel twice as long as standard. Build a "shroud" that screws on to the back end of the threads, then pin and weld it so it becomes part of the barrel.

If I can find the write-up about the CZ/SIG, it should make more sense.

Ok. Not exactly what I was looking for but this is the exact thing I was thinking about.

In this picture, the outer part that's around the can is part of the barrel.

Tactical Solutions does this for the 10/22 with their SBX barrels. Other than working around the dimensions of your can and handguard, I don’t see why it wouldn’t work on an AR.
