None (legally, see what systolic says below), it's the just way the police explained how they measure the end of the barrel.

That's not in law, but is something to do with the agreement between the cops and Pistol NZ I think.
There's a couple of approved pistols with barrels under four inches, but are approved because they are only designed for ISSF type target shooting.

Basically right. Personally not aware of examples where under 4" barrels are approved however. PNZ agreed to this with police, so they treat it like they have some law to back it up. There's non PNZ clubs that have not agreed to anything PNZ have said.

See what is said at the top of that link.

Not trying to start an argument at all, just trying to clarify. I think your document may be the 'old' one that the blog refers to which the measuring interpretation was later changed?

It makes sense to me as removing the stock (but not buffer tube) from an AR-15 rifle is probably faster than removing a lot of muzzle devices and it would also reduce the length. You would lose the detent pin if you removed the stock but the rifle would still be able to be fired.

Alright, for one, the document I linked is on the police website so is far more valid than anything on any blog. Secondly it says:

“To determine overall length of the MSSA the measuring should start from the closed or folded stock position to the end of the flash suppressor, providing the flash suppressor is firmly fixed to the firearm in such a way that a tool is required to remove it.”

Now, reading that it first says MSSA, so that excludes ALL A category firearms, then it also says "flash suppressor" so that implies 'flash hiders' only, not muzzle breaks or suppressors.

Thirdly, I'm a FOUNZ editor and a PNZ member who takes great interest in this stuff if that cuts the cake for ya

The standard Sig Mosquito has a 3.9" barrel. Would have been doing everyone a favor if they didn't get approved though.

That is cool that you’re a PNZ member, so am I and with all sincerity that is great that you are a FOUNZ editor and that you take an active interest in the law/gun politics. I do appreciate that the KiwiGunblog is only a blog but it does seem well informed. The same information however is also posted on that Pistol NZ Website link I sent you and I do put stock in what they say.

The same is also in the Deerstalkers newsletter http://www.wairarapanzda.org.nz/wp-c...newsletter.pdf

The Pistol NZ link I posted for you to look at states:

"On the 13th of September the policy position below was distributed internally and externally. Since then I have been asked to provide clarification as to the points to be measured from and to. To determine overall length of the MSSA the measuring should start from the closed or folded stock position to the end of the flash suppressor, providing the flash suppressor is firmly fixed to the firearm in such a way that a tool is required to remove it.

This contrasts with your link to the Police page which says:

Classification:
• MSSA firearms will be measured in their “reduced state” (buttstock folded or
collapsed) in order to determine their classification.
• Rifles and shotguns which collapse or fold, and which can still be fired in this
reduced state will be assessed for classification in the reduced state.
• ANY firearm which is less than 762mm will be classified as a pistol.

The length of any firearm is measured without any “attachments” (whether or not
“permanently” attached (e.g. welding, pinned)), such as flash-hiders, silencers,
muzzle brakes, or barrel extensions. - It then goes on to talk about barrel length.

It appears that the document that you refer to on the Police website which says length does not include a flash hider came out sometime in March 2017, and that a change, in that length does include a flash hider, came out from Police in September 2017.

According to Supt. Mike McIlraith this was sent to various groups outside and inside the Police, but that clarification does not appear to be on their website.
A lot of muzzle brakes (including the ones I have) are also flash hiders. I think they just say flash hider as that is a part of the definition of an MSSA. Whether it is a brake or flash hider, it surely is more important that it is “firmly fixed to the firearm in such a way that a tool is required to remove it”, but maybe that needs to be further clarified with Police.

As I said before I am not trying to start an argument, the only reason I asked if there was someone was here from the Kiwigunblog or Pistol NZ (I meant the people that run Pistol NZ) is I wanted to see their source document from Mike McIlraith. If anything it is the Police’s fault for not updating their website.

I'm going to be building an E cat AR-15 with an Oceania Defence QD can and I asked this very question on a thread (see link below) recently hence why I am so interested in it.

I haven’t read anything about A cats being measured differently and I suppose that is a question that should be asked to see if it the same as the way MSSA’s are not being measured (I.e if it is from the firmly fixed muzzle break to the end of the stock).
