Major relief .. After several people telling me different I was thinking i cut to short . Thanks Larry !! this is perfect !

[@davetrevino1361]

Excellent walk through. Saved my dad's old "sawed off" pump which is legal knowing how to measure properly. Thank you for this clear, well made reference.

[@Win94ae]

I have not seen MidwayUSA ad on youtube in a few months. I see a placeholders and hear some audio, for a few seconds; but never does a whole ad play. Just wanted to let you know, in case you expected ads to play.

You can always count on Larry to give you the straight answers minus all the hyperbole. Thanks for all you do Larry.

[@HiLuxInc]

Always a useful topic to cover! Some rifles are just simpler to measure than others.

[@Southernguitar74]

I love the guns used in this video.

[@meyhemmolly]

Thank you very much for this video. Way to many "experts" out there telling conflicting stories.

[@PerfectoM]

Thank you for the information. This video was very helpful and keep up the good work.

[@TheFirearmEnthusiast]

Right to bear arms... that have the correct barrel length.

[@shadowblack1987]

Ofc.

Thanks for the info Larry.

I have always wondered why the chamber is considered part of the barrel length on rifles and semi autos but not on a wheel gun. Is it because the chambers on the wheel gun are not physically attached to the barrel? It always seemed to me you weren't getting an accurate barrel measurement when measuring to the breech face.

[@numberpirate]

Thanks for the info in this, I was wondering whether it was from the breech face or where the end of the case is.

[@michaeltuber4036]

Dude I read your name really fast and I read it as my name accidentally because they sound similar lol

[@CHIBA280CRV]

Fantastic informative video , thanks 👍🏼👍🏼👍🏼👍🏼👍🏼

[@karljackley4423]

Ok, how about a revolver rifle. Such as a Taurus Circuit Judge. Back of the cylinder or front? The reason I ask is I have one. And it is 16”. But while out shooting. It slid and hit the muzzle against a rock. I need to cut an inch off to clean it up.

[@marscobras8281]

thanks midway usa

[@uncasnetewateweslenape2383]

I had a Stevens Crack-Shot...that rear sight was replaced, just like I had to do to mine...original had no elevation adjustment...

[@TheTimeshadows]

I recently read on a manufacturer's website that Pistol Caliber Carbine barrels are not measured in the standard fashion, and that it is important to know the proper way to accurately measure them, but, they did not provide instructions how to do so. My Google search brought me here, but there is no specific indication, with the possible exception of that magazine-fed rifle, to suggest the proper method. Help?

[@DrFillyBlunt]

So you're essentially saying as far as the wooden dowel will go is the barrel length?

[@j83460]

thanks, helpful for nfa grace registration

[@saltydogsusa6382]

Terrific Video. Thanks so much for the info.

[@GeraldThomasphotojunkie]

Very informative. Thank you!

[@slowpoke5378]

Is bullet run ever considered in barrel length? eg: a 24" barrel 30-06 vs 24" barrel .22. The .22 has more true bullet run than the 30-06 do to case length and is that why the bullet manufacturers use 26" test barrels.

[@GatofieroYT23]

How do you deal with fractional inch measurements? Do you round up, round down, round to the closest 1/4 inch?

[@thomasmack3195]

What is Is

[@Jonj57]

@@thomasmack3195 Don't round, if push came to shove and you're under you can be charged. It's likely that if it's really close they wouldn't care, but why go to prison over an 1/4th of an inch?

[@versoarmamentcompany]

Great video

[@MavHunter20XX]

How silly how they determine the barrel length while the cartridge length and action can lengthen the firearm. Makes you wonder what justification they have to restrict a firearm if it's too short.

[@shelleyanthony1305]

MavHunter20XX it should be the same as the shotguns and rifles.

[@Laotzu.Goldbug]

So essentially, accepting revolvers, just put any firearm fully into battery, and stick a dowel down the barrel, and measure. I guess this could be a pain for AR-15s that have a muzzle device that isn't permanently attached, but doesn't _easily_ come off

[@nickknight8065]

Measure the outside length of your muzzle device and subtract. If the muzzle device is pinned and welded, it can be included in the overall length.

[@avalon449]

What happened to the video from today, Jan 8th? It was there then taken down.

[@CALVINLNIKONT]

Why don't you do a video on how to slug a barrel?

[@antoniofiammelli1792]

Larry why not ship to Canada I buy a lot from cabelas brownells midsouthshooters etc are you not interested with the Canadian market

[@gilfaver362]

Terrific info. Thanks.

[@bdk316]

Soooooo how do you measure an AR?

[@EmoFox9]

not fully correct good buddy, if your flash hider/compensator/muzzle device is removable, you screw that off first, then measure from closed bolt to end of barrel as seen in video

[@christianewing1113]

Wow I thought the chamber didn't count but I guess it does. Thought my AK was under 16" but I guess it's not. Thanks for the info!

[@justinjohnson2657]

Let's repeal the unconstitutional NFA. Shall not be infringed.

[@JustAnOldMan]

Why does a semi-auto pistol include the chamber, but a revolver does not. Either one should have to minus the chamber length on a semi-auto, or the cylinder should count as barrel length on a revolver

[@bceyler6522]

Boo ATF

[@dallagassa1]

so all firearms are measures from the breech face except for revolvers ... would you happen to know why they are measured differently?

[@ElijahDecker]

+Lino Dalla Gassa Probably because they don't have a breech.

[@dallagassa1]

thanks ....Just seems odd.

[@EmoFox9]

because on revolvers the barrel ends at the cylinder

[@donaldmack2307]

Ab to go 18.75" on my 870!

[@the_chomper]

that "rule" about measureing down the bore is not actually written in law. its barrel length not bore length

[@johncosta110]

Hi Larry i’ve been watching KZbin how to give great I have a 17-year-old Cobra Derringer trying to take the handles off but the screws are don’t look like a screwdriver would fit it in there more like a river could you let me know what to do before I start your friend Walter don’t want to ruin the gun thinking of grilling out the truth looks more like a River attended screw small hole in center of screw no way to pull it out with us from there please let me knowThank you and God bless

[@marryson123]

We are learning how to comply with tyrannical draconian law here.

[@smonkspook9932]

you guys are complying?

[@3asianassassin]

Psychopathic loser

[@ZAPSquad-rb3hj]

It's so stupid that a revolver pistol doesn't include the cartridge length/cylinder, but the semi-auto pistol does.

[@Laotzu.Goldbug]

Z.A.P. Squad it kind of makes sense though. In a semi-auto, the chamber is an integral part of the barrel, it's literally the same piece of metal period for a revolver it's not. The cylinder is constantly changing, and it's certainly not the same piece of metal

[@michaeltuber4036]

I don't think they mentioned to safety check the weapon which is rare on KZbin gun videos.. Even though he checks it's not stated to do so which safety nazis get crazy about. But overall great video.

[@morganfreeman3310]

U didn’t even do an ar

[@HeathLCK]

Repeal the ATF & NFA

[@jamess.829]

You are not allowed to have a short barrel... unless you pay a tax and give us your money!!! Makes no sense.

[@jameswardle7257]

Much safer to measure barrle lenght to measure from where barrel meets the receiver This allows no margin for error Also note a barrle longer then 16 inchs Rifle barrle so make it a bit over 16 inchd pleade

[@Jonj57]

It might be safer from a "cop doesn't know any better" standpoint, but the ATF official docs say breach face to end of muzzle. Keep an extra half inch over that so there's no change of someone reading a tape wrong on rounding.

[@L.Fontein7]

Difficult to see what you're doing as your hand is in the way and you go to quickly.

[@burtcokain5473]

Be sure that you "mayshure" it properly

[@oneshon500]

Not what the title says

[@bigred2989]

Wish they would get rif of this SBR/SBS BS. It's a waste of time considering how easy it is to get things like stocks for pistols. In other countries there's no hassle when you put a stock or suppressor on a Glock, though that might be because of the hassle you went just to get the Glock in the first place.

[@TheAlexagius]

the whole nfa is pointless
