I have a Rock River LAR 15.



About 3,000 rounds through it. Factory stock, 2 stage trigger, and quad rail. Retractable bipod/foregrip. Magpul trigger guard and BAD lever. BRO flash suppressor and Nikon 1X4 scope.

Great gun. Never had a jam or misfire, and I've ran 1,000 steel rounds through it.

I want to turn it into this.




Minus the tan. Keeping it all black. I might cerakote it later.

I really like the Noveske flash suppressor.



I've order the SB 15 sig brace. Do I need a different buffer tube? What's the shortest barrel and quad rail combo? Red dot/green dot sight to look at? Acog?


Any advice or tips are appreciated. TIA

You'll have to fill out the paperwork and make it a sbr. Might as well put a real butt stock on it then.

You're gonna need a pistol buffer tube for it, yes.

The shortest I would go (for sake of muzzle blast) is 10 inches.

Why do you want a quad rail so bad? Are you gonna be using all that space or just like the feel of it?

Aimpoint and EOtech are my personal favorites.

The email that circulated was merely an opinion of an ATF official. They didn't go through any proper channels to write a new law so the law didn't change.

You don't need SBR paperwork to run a pistol buffer and a Sig brace.

Just don't let anyone see you shoulder it

Moral of the story, the ATF is dumb.

I wonder how many "felonies" were committed at SHOT show.

The ATF is dumb, but there's a nuance here the OP has to remember. If the lower he has now was originally built as a rifle, it is forever a rifle and cannot be converted to a pistol without the proper ATF approval. He would have to get a stamp for that lower and it would be considered an SBR since it was originally a rifle. It's dumb, but that is the law.

OP - you could add the brace and leave the longer barrel on it and you're fine. If you want to go with a short barrel you're better off to buy a new lower that hasn't been registered as a rifle and go from there, then you can build an AR pistol like in the picture.

I'm not talking about the Sig brace. I'm talking about the short barrel on the second gun.

You cannot create a pistol from a rifle. Only a rifle from a pistol, but once that lower is configured as a rifle it is always a rifle. Its dumb, I know, but if he takes his gun. As pictured and turn in to the other gun that's pictured he will make a sbr.

ETA: looks like the peeps above beat me to it.

Still don't know about going back and forth between pistol/rifle and back again. I'll have to check up on it again.

Can't do it legally. A rifle is always a rifle and a pistol can be either.

As stated by others, you cannot turn your current rifle into a pistol. You can buy a new stripped lower for $50 and put a pistol tube on it and then switch over all the parts you want because the new lower will have never been a rifle.

How would the ATF know what your lower was built as previously? I've always wondered this

In theory it's based on the original manufacturer's reporting, which is a type of Form 1, or the Form 4473 (I think) when a gun or stripped lower is purchased and the background search is done. That's why when buying a stripped lower the buyer should always have it listed as a pistol or other device instead of calling the stripped lower a rifle.

In reality who really knows.

Preferably, list receiver as firearm or other.

Once a rifle always a rifle as stated earlier. Just order a blew lower and it will get called in as other and you will be good to go.

Don't take photos of yourself firing the sig brace on your shoulder as the ATF makes up its own laws now. If you want an sbr just Form 1 with a trust and wait 30 days.

with the wait time these days it's even more tempting for me to build an SBR.

Yup, eforms form 1 with trust is super fast at the moment.

I was told eforms will allow form 4's soon as well.

Thanks for all the info guys. I'm currently out of state, but next time I'm in LA I'll but a striped lower and file it as a pistol at purchase. Any recommendations on lowers? I ll probably just build a complete lower in that case. Timney 2 stage trigger or Rock River 2 stage trigger? Best pistol buffer tube? 10" barrel... What's the best? I'll shoot this gun a lot. I don't need a quaff rail. I think I'll have a foregrip like the one seen in my second pic. Possibly a light/laser combo.

You don't have to "file" the stripped lower receiver as a pistol. Just purchase receiver and assemble as pistol.
