762mm seems like such a random number? Is there some common reason that is the length of choice?

Wasn't there some new policy recently regarding where/when to measure the 762mm minimum length for a collapsible/extendable stock? Is it when the stock is at full extension, allowing the firearm to be under 762mm when collapsed? Or must it be over 762mm at all stock positions?

My AO says from collapsed, but I believe @Digit 's AO says extended.

yep, to where the rifling ends, and muzzle devises do not count as added length even if said device is pinned/permanently attached

Is there some written reference to this? I believe you both, but it would be great if we could see the original document. "Because X and Y on the NZHS forum said so" probably won't fly if someone ever gets pulled up on this.

I already know what some of you are going to say, but this is good enough for me

Folding Stocks

New Interpretaions

Thanks to a recent court ruling decision that came from a new Crown Law Office interpretation of MSSA’s. Folding stocks are part of what makes an MSSA Always have been, so there has been new clarification as to how the minimum length of an ‘E’ category firearm is measured. Previous interpretations had been confused and contradictory, depending on the Arms officer involved. This is unfortunate.

Some measured the stock open, some closed. Some would not measure any muzzle break that had been fitted, even permanently Correct – the barrel length is measured against the rifled barrel, in the case of a rifle, and does not include any attachments, no matter how attached. This is standard practise used by the Police Armourer. Some ignored a permanent suppressor tube, even when the ported barrel prevented the weapon being discharged without it fitted. Correct.

Now the minimum legal length of 762mm will be measured when the folding or collapsing stock is OPEN Correct in the case of an E-cat firearm. Our understanding is that this only applies to ‘E’ category arms Yes, they are a special case. So if you have a pump action shotgun with a folder then minimum length will be measured when folded Yes. A standard (“A-cat”) firearm cannot be reduced to pistol length or below at any time.
