I wanted to do a suppressed 9mm AR build. I was thinking of using a 11" rail with a 5" barrel underneath, so my suppressor would be under the rail. Would having the 11" rail count for the OAL?
Thanks

Does Handguard Length Count for OAL?

Pin the suppressor in place?
No, it would not.
How to measure.
Stock, if movable, fully extended, any muzzle device not pinned or permanently attached removed.

I might do that or make it a pistol

Im guessing it wouldn't make a difference if the handguard was permanently attached

Does not count.
Only if it were permanently attached to your muzzle. In other words, no can do.

No.
It must be attached to the barrel given the method of measuring OAL that the ATF mandates:
They count only "permanently attached muzzle devices" as part of that. If the thing doesn't permanently attach to the barrel, it's not a muzzle device, and in that case the rail is part of the receiver, not the barrel.

Well looks like im making a pistol until I move out of state..
That is my current plan for my 9mm build. But as my can is still in jail, I may reconsider once I take position of it.

So what we really need is for someone to sell a suppressor shroud that can be pinned and welded onto any barrel (rather than the TacSol barrels and uppers) so the suppressor itself can still be removed. Obviously you'd either have to have a selection with different threads and shroud diameters, but somebody has to be able to make money on this, right? It's gotta be cheaper to do this than weld on a suppressor.
Downsides that I can see would be the risk of loss of concentricity if the thing isn't aligned right as well as the need to use direct thread mounts (or mounts that can be removed without having to manipulate whatever is covered inside the shroud.
Found somebody with the same idea, but looks like it hasn't been executed yet: https://www.reddit.com/r/NFA/comments/3hv27c/xpost_300blk_permanently_attached_suppressor/

Im just wondering how that would work to have a suppressor welded to the barrel. A lot of suppressors disassemble for cleaning. So would I have to have the whole suppressor welded together or only the booster part welded to the barrel?
It would depend on how much length you are trying to achieve. The fixture has to be permanently attached so...
In my case(5'' threaded barrel), I think I should be able, if I wanted to, permanently mount to my barrel. Time will tell. I'm only here another 4/5 years. I may just wait.
Possible with a form 1 build. Weld the direct thread adapter to barrel and shroud. Leave the end cap "loose". Does this sound legal? This is something I've been pondering.

Just be careful about pinning. A lot of suppressors have a piston that threads on to the barrel then a shroud that threads on to the piston. You would need to pin and weld both parts or the suppressor can be removed.

Giant extended butt-pad, so that the stock is the proper length when retracted, and extra long when extended?
