How do you measure the bbl length on a Winchester M12?

Do you measure just the bbl (so the section that you can remove)?

Or do you take the action/receiver length into consideration?

Thanks

On pumps I have always measured them from the point where the action meets the barrel to the muzzel.

M12's are not like other pumps. You need to include in the total length the portion of the barrel assembly that fits into the receiver. That's why so many of the M12 listings on the internet are incorrect.

With the gun assembled, stick a rod or dowel down the barrel until it's against the bolt. Mark that and measure it.

Jim has it right, from the closed bolt face to the muzzle.

That sounds right. The legal definition says it should be measured from the 'point of detonation' to the exit point of the muzzle with any attachment such as extended chokes removed. Lagopus.....

Cool. Thanks for the info, guys.

All the above answers are "right"- when you measure with a dowell, against the closed bolt "in battery" and make a hash mark where the muzzle ends on the rod- you are right-if you add in depth of the headspaced ring that is inside the receiver. I always dis-assemble and measure from the exact rear of the thread lead to the muzzle- if you research Dave Riffle's book on "The Perfect Repeater" which the Model 12 most certainly is, you'll see the odd 26 & 3/4" developed barrel length when they had the ventilated rib for the 26" barrel guns on their Skeet guns.. RWTF.

That's the way we have to do it "up here" for the National Registry ... and to verify the guns against a common data
base ( FRT - Firearms Reference Table) for registration.

PS: The whole registry system sucks ... the long gun registry
doesn't prevent crime whatsoever - just penalizes the
average gun owner. Criminals don't register their guns.

Saying "guns cause crime" is like saying "pencils cause
spelling mistakes" ... pure rubbish.
