I have a LaRue 12" Stealth which will be going on a LaRue Lower w/ a CTR stock.  I guess I am unsure how to answer the Barrel Length and Overall Length question.  It has an A2 FH on it now, but I have a BattleComp on the way.  

Thanks guys

Measure your barrel without the muzzle attachment.

Measure your overall collapsed.

Barrel length is for the barrel itself without attachments.

Measure your overall collapsed.


OAL for this purpose is with the stock extended.

This is what frustrates me.....



No matter where you ask this question, you get multiple answers....



So, what are each of you basing this on???
I wish the ATF would clearly spelll it out on their web page and the form...



I mean how hard would it be to say, F. OAL Extened or F. Overall Length Collapsed....

The overall length of a firearm is the distance between the muzzle of the barrel and the rearmost portion of the weapon measured on a line parallel to the axis of the bore.

Well I guess you could always just call the ATF and ask yourself,that way you get the answer straight from the source
Not trying to be a jerk but OAL means overall lenght. Now if you measure your OAL with the stock collapsed that isnt going to be the correct measurerment. Cause guess what happens when you extend your stock all the way out, it gets longer

The federal definition of a rifle is a firearm designed to be fired from the shoulder.

Some rifles are capable of being fired with the stock collapsed or folded; others, however, cannot be fired unless the stock is fully open in the firing position. To be consistent and eliminate confusion between the different types, ATF always measures rifles with the stock unfolded or fully extended.

You can call ATF Tech Branch and that's what they will tell you. Or you can listen to folks who have been dealing with ATF for decades, and that's what they will tell you.

You are correct that ATF should have this written down somewhere. They do not. Same goes for many other regs that ATF should publish, but they do not.

It's somewhat obscure how they mention it, but there are numerous various references in the NFA handbook covering this.



To cite one:



NFA Handbook, Page 21, Paragraph 1, Lines 3 through 4.



Paraphrased: "and the overall length of the firearm, with stock extended, is more than 26 inches"



It's specifically speaking about AOWs in that section, however, there are other references to be found. The official ruling is 26 inches OAL with the folding or collapsable stock fully open or extended.

They wrote it in the NFA handbook, as I quoted above:
The overall length of a firearm is the distance between the muzzle of the barrel and the rearmost portion of the weapon measured on a line parallel to the axis of the bore.


"rearmost portion" means the stock must be extended.

If the stock (like on an AR) is collapsed fully, and you measure, you are not measuring to the "rearmost portion" of the weapon.

That's been the accepted arguement, but I'm absolutely positive that I saw actual verbiage from NFA branch regarding this question.



OP, short answer is 26" with stock extended. Military 10.3" barreled MK18s are just over 26" with the stock fully collapsed, and 29" with it fully extended. The OAL requirement is almost non-pertinent to the AR platform. It mostly affects bullpup style weapons and pistol grip shotguns6



You're going to be FAR under barrel length requirement before you even get close to the OAL requirement.



Don't stress the minutae. It's not relevant to your situation.

I just got a stamp back for a 10.5" AR.  I put down the OAL as 29.5".  Put yours down as 31" and be done with it.
