Difference between AR pistol lower and Rifle lower

[jackrv]

This is probably not the right place but, for those who build, what is the difference between a lower used on a pistol and a rifle?

They are physically the same. A new lower receiver is designated "other" because it hasn't been used as either rifle or pistol. Once made a rifle it must always remain a rifle. A pistol lower receiver can be changed back and forth as a pistol or rifle.

Physically nothing. Learned something from the above post and changed my response.

The answer is time-of-purchase paperwork, (rifle/pistol/other) plus the fact that you're not allowed to have a rifle stock on any pistol unless you get a federal tax-stamp to register it as an SBR, short-barrel-rifle.
Another poster mentioned changing a pistol lower back or forth from rifle to pistol; Pistol lower/tubes are specifically not designed to hold a stock and a rifle length upper on a lower without a stock is very unwieldy. Most people figure it's better to not swap around due to potential legal issues. If you set it up as a pistol, leave it that way.

Thank you all.

Damn! That was confusing. I wonder if LE could figure all that out?

NOTHING AT ALL
Both are identical or I should I say, are "others" until built.

I build all new AR receivers as a pistol first. This way there is no confusion as to whether it can be made into a rifle or pistol later.

 

[edslhead]

I don't get it? Who would know?

 

[orygun]

Just build it as a pistol.

ATF reverses stance on shouldering pistol braces!

Once made a rifle it must always remain a rifle. A pistol lower receiver can be changed back and forth as a pistol or rifle.

Those two sentences contradict each other. What you mean to say is once a lower is TRANSFERRED as a rifle on a 4473, then you're stuck with a rifle. If you buy a stripped lower it will be transferred on the 4473 as "other," and you can go back and forth
))<>(( as many times as you want.

What is this 4473 you speak of???

The only difference you need to worry over is that women love men who have pistol lowers, and laugh derisively at men who only have rifle lowers.

With an 80% lower, is there any problem making it as a pistol since it is manufactured and never transferred?

Ha. Haha. Haha haha
