How to measure overall lenght???

1207 Views 12 Replies 6 Participants Last post by  Cammer
I have looked and looked but I have not found the section on how to measure overall lenght of a rifle. I know it has to be 26 inches or more but if you have a folding stock, is it measureed with the stock open or closed? Does naybody know the section where this is listed? :confused:

The overall length of a weapon made from a shotgun or rifle is the distance
between the extreme ends of the weapon measured along a line parallel to
the center line of the bore.

Federal Firearms Regulation Reference Guide

Part 179 definitions 179.11

I didn't actually find the reference there to "being closed", but I would count on it.
thanks for the reference. some people are building amd 65 and lengthening the bbl to 16.125 and measuring the muzzle to extreme point of pistol grip.

i'm soldering triangle shaped sling loops to the rear trunnion to get the strait line, and the sling point.
The OAL is measured with the stock closed.
Remember it must be locked closed until after September.

26-3/8" OAL.

Ok, but when the ban is gone how is it measured stock open or closed? And where is the documentation? I have one with the welded stock open which I want to correct in Sept. I also want to remain legal.
The ban will have no effect on the length. It is covered in the '68 GCA and NFA.

It (the awb) has to do with folder/telescoping, flash hiders and bayo lugs assuming of course you have a detachable magazine and a pistol grip... :)
The 26" OAL was was part of the National Firearms Act of 1934.

Don't look for it to change anytime soon :)
OK, again , the OAL length of a folding stock rifle is measured from the muzzle to the butt,in the extended position.

The USC definition of a rifle includes the term 'intended to be fired from the shoulder' , hence the OAL is measured from the muzzle to the end of the stock,WITH the stock extended.

For illustration, a Norinco Type 56s folding stock rifle measures 25 3/4 " in length WITH THE STOCK FOLDED. If the OAL length were measured with the stock folded, this rifle would be illegal, and I can assure you the Anti's would have prosecuted anyone who owned one.

The Type 56s folding stock rifle I-S legal , was ATF approved for importation , and was legally sold as a Title 1 firearm.


*note* - I am addressing folding stock rifles not rifles with the stock welded closed.
From James Bardwell :

A short barreled rifle is a rifle (which is defined as a shoulder
fired, rifled bore firearm) with a barrel length of less than 16",
or an overall length of less than 26", or any weapon made from a
rifle falling into the same length parameters (like a pistol made
from a rifle). In measuring barrel length you do it from the
closed breech to the muzzle, see 27 CFR sec. 179.11. To measure
overall length do so along, "the distance between the extreme ends
of the weapon measured along a line parallel to the center line of
the bore." 27 CFR sec. 179.11. On a folding stock weapon you
measure with the stock extended, provided the stock is not readily
detachable, and the weapon is meant to be fired from the shoulder.

Thanks T66, you answered my question and I was able to verify the info. I fully understand the 26" overall length was not part of the 94 ban (as some have pointed out). However the folding stock on post ban rifles was part of the ban. My folding stock is now welded open. If I remove the weld, the overall length with the stock closed will be under the 26 inches.

The clarification with references will help with my comfort level when Sept arrives.

I have plans on a Polish PMKMS build utilizing the underfolder. I noted that the OAL with the stock folded is approx 25.75 inches.

I just wanted to say that this is also a question that I had. Thanks for clearing this up T66. :cheers:
