SBR or Sig Brace

Honestly I'd do the SIG brace with a KAK buffer tube. The SB15 fits like a glove nice and tight on this buffer tube and it gives you just enough LOP to shoot comfortably and be compact. If anything, try the brace while you wait on your SBR paperwork. It'll make the wait a lots less grueling.

For vert forgrip just make sure OAL >26". Whle it is crystal clear that removable muzzle devices don't count toward barrel length, the ATF contradicts themselves when it comes to whether they count to OAL (I have an old thread on the contradictions).. To be safe, don't count it. You are dealing with folks who possess the power to call tomato a vegitable rhubarb a fruit, thighs genitals, and dinosaur bones Native American artifacts . . . and get away with it. It is best to try to do what suck people want/expect.

For the cost of the brace, I'd just be patient and SBR the lower, then you can do what you want with other short uppers down the road. Want to take it out of state? Either submit the form or just slap a 16" upper back on for the trip.

The thing with the brace is it doesn't say where on the tube it had to be placed. So, I could put it on and leave a comfortable distance between the lower and the brace and still be fine.

KAK makes a pistol buffer for use with the sig arm brace it is slightly smaller diameter then a normal pistol buffer and I think it is about 1.5" longer. It will put the brace at about the midpoint on a collapsible stock. I talked to them last week about it the diameter that they made the new tubes to hold the sig arm brace snugly but not stretch out the sig arm brace.

The two versions are the super sig (with a castle nut) and sig (without the castle nut).

My buddy just completed his pistol with the sig tube. I like the look better but not sure of it without a castle nut.

With the NFA wait time at something like 15 months right now? Not sure I'd be that patient.

And, with the SIG "brace" you can do whatever you want with uppers at any point.

Can you take an SBR'd lower with a non-SBR configuration across state lines temporarily without notifying the ATF?

Yes. So long as you don't take your short upper(s) with you when you go. (Actually says "retain control of them.")

Something else to think about is (in Washington, not sure how everywhere else is) you can have a loaded pistol in your vehicle, can't have a loaded rifle.

I'm in the same boat, and I decided to just go ahead and SBR it. I'll eform it with my trust so it should only take 3-4 months to get the stamp back. SIG brace seems easier/quicker but a stock will be more useful (IMO at least)

Yes you can.

The wait isn't that bad, I did an eform for my suppressors Oct and they took 3.5 months. It's up to 4 now I hear. Either way, eforms are quicker but Sig brace is simpler.

E-forms are still running about 95 days last I checked.

I have both SBRs and an SB15 brace. The issue for me isn't about doing the paperwork for an SBR but how long a 5320.20 takes to be processed and returned. I wish they had made 5320.20 an eForm for faster processing but if wishes were horses...

Also, don't forget the cost of engraving a Form 1 SBR ... that's another ~$50.

For what it does, yes. Obviously an SBR is more versatile. The brace can rotate on the my KAK Super Sig tube - especially if it gets hit on the bottom where there's more leverage. Haven't decided if I'm going to hairspray it in place yet (as with bike grips).

That's what I'm hoping for.

Why aren't more people using a trust and e-filing while it's still an option?

The cost of a trust is small price to pay to not wait 10-15 months.

SBR.

I wouldnt invest in, or wait around to see when or if the ATF decides that the Sig brace isnt legal anymore. If they do declare it illegal to be on a pistol, its going to be pretty much worthless.

The recent hoopla about Ares Armor and EP on the 80% poly lowers comes to mind. It doesnt have to make sense, but in this day and age where the ATF gets a wild hair to start cracking heads, the Sig Brace would be the easiest of targets.

Eeeeh. Like with the ARES issue going on right now, if they really want to know, they'll just subpoena the receipts and records. Yes, that's not as easy as just looking in a registry, but you aren't in any way anonymous.

(Ok...so you bought at a gun show, in cash... most don't.)

You make a great point, but I would have thought the slidefire stock would have been in the same boat by now and it hasn't had any issues. At least with the brace they don't know who has them but with the SBR they know where to find you.

That same logic could be applied to other NFA laws.... why even get a Sig brace? why not just have an "extra" retractable stock laying around? I mean, ATF doesnt know who owns stock either, right?


The slidefire stock was allowed because it was a very cut and dry rule that they were basing it on, one of the rules ATF has been consistent on. A firearm is considered to be non-FA as long as one pull of the trigger meant one bullet fired. The slide fire stock just makes you pull the trigger in a bump-fire fashion.

The decision on the Sig brace is one that could go either way. If someone decides that people are actually using them to fire from the shoulder, and they want to call it a stock, then it will swing it to being illegal.


Just like what happened to Ares armor, if the ATF wants to know who bought a Sig brace, then they will seize all the customer information about who bought them and from which distributor.
