SBR questions

jmike1487 · Feb 24, 2015

I just want to start of by saying that I searched this fourm for awhile before posting this question.

I am interested in getting into a little bit of class 3 items sbrs suppressors etc. I bought a smith and Wesson mp15 right before the 10.1.13 ban went into effect.

My question is would the OAL length of 29" still pertain to me since it was purchased before 10/13. I know if it was sold as a Rifle you cannot change the configuration into pistol. But I would assume a sbr is entirely different. With the amount of knowledge on this forum I figured this would be the safest place to ask. So please be gentle haha.

I currently have a aero lower with a 10.5 upper on it. I completely removed the sig brace on it. . That was fun while it lasted.

I don't have a trust at this time. I wanted to ask a few general questions before taking the diving right into getting a trust set up.

Or would it be smarter to sbr the other lower?

The > 29" OAL applies

I would go this route. Keep the pre October setup as is since you can't replace it.

Simple question to a simple answer. Thanks. Just one more. I'm gonna just keep the set ups the way that they are right now.

With that 10.5 upper would it be enough for 29"? I would just replace the buffer tube to accept a stock. But only after all of the paper work went thur.

Depending on stock choice I think 10.5 is about as short as you can go. At least without pinning a flash hider to the barrel. 10.5 is a great setup and anything less is just a loud range toy (in my opinion).

I don't wanna go lower then 10.5.

swinokur · Feb 24, 2015

I have both a 10.3 and 10.5" uppers. They both are just a tad over 29".

I am using a PSA stock.

Put in a form 1 for an SBR on the post-october lower.

There's no sense in "wasting" a pre-october rifle when you don't need to.

I was just going to say, 10.3" should make the cut.

So now I need to get a trust. Where would you all suggest I go? I know that it's a big deal with everyone using the 199 trust and others. I just want to see what my options are

Check the Legal section under Industry Partners. There's 3 good options there.

This is a good call.

But If you are comfortable with an online trust, 199trust is a great option. I got mine from them.

I don't want to start another thread, but lets say I purchase a post 10/1 lower to SBR. If I make it > 29" with a 10.5" 300BLK upper that shouldn't be an issue. As long as I keep the 10.5" config, can I put a mag block and a 9mm upper on it and send a letter to the ATF?

What if the 9mm is < 29"...no go, right?

swinokur · Feb 25, 2015

IANAL, but as long as you can return it to it's original configuration, BATF doesn't require a letter.

OAl 29" or > GTG.

<29"-no go

as long as its over 29", but cant you change it after its approved to shorter or longer? legally that is

No, as you'll be creating a "Copycat weapon" which is illegal under MD law. Also it's less then 29 inches (<29"), not more than 29 inches. That little extra length can be a big plus on some builds. And it doesn't "poke the bear" as some would say. Just read that particular law section closely and you'll get most of what you need.

MD Article - Criminal Law 4-301

Pinecone · Feb 26, 2015

You can make it longer after approval.

Just don't make it shorter than 29", at least for now.

jmike1487 · Feb 28, 2015

So when measuring to get OAL length what do you measure. From muzzle device to end of the buffer tube? Or take muzzle device off and then measure? I just want to get it right.
