shortie 10/22

Saw a pic of a members 10/22

i dont remember what thread i saw it on, does anyone know info about this barrel? legalities?

I believe that is a 8.5" barrel from ?Fabsports?

You can have factory made barrels below 18.5" on rimfire rifles. So, a barrel that length is fine as long as the OAL of the firearm exceeds 26".

That would be mine. 100% legal. Standard stock carved out to fit the heavy barrel. also the forend is cut back so its flush with the thick part of the barrel. As Nine said its an 8.5 inch barrel purchased from fabsports. Register as "less than 470mm" and still non-restricted because the OAL is above 26 inches.

taking a 20'' bullbarel .22 and cut it to 16,5 '' and keeping the oal to 26'' , it is légal ?

 

[pc9]

No you can not cut a factory barell under 18.5 inches.

thank for info !

how accurate is that 8.5" barrel?

Actually, it's a bit counter-intuitive, but a shorter barrel is more accurate.

It has to do with the way your barrel resonates when you fire a round. It's called barrel harmonics.

A shorter and stouter barrel will vibrate less, and thus be more accurate.

BUT, you will lose some velocity, because the gas will not have enough time to fully expand in a shorter barrel.

interesting ! It must be fun to shoot im guessing it kicks alittle harder than an 18" barrel would.

thanks

There's kick to a 22lr

Seriously... That's the same barrel that was used in the Krinker-plinker kit... Works good... and you even have a little muzzle flash

Does barrel harmonics really apply to a little round like the.22LR? What I have read was talking about centrefire rifles, nothing about rimfires. Can someone confirm...maybe with some backup data?

Thanks.

Put Minimags through an AR-7...

Now, is that to a certain degree such as a within x yards the shorter barrel preforms as good or better then a longer barrel. Otherwise, if it was general, wouldn't the army be using short barrels on their long range firearms?

You answered your own question there, Lone-Wolf. The further away the target is, the more energy you need to put behind the bullet for it to be effective when it hits. It's all about finding a happy medium.

with centerfire i've found you lose 25fps per inch of barrel & I can't see it being any more with rimfire. this is not a huge amount. plus subsonic rounds are more accurate.

 

[lone-wolf]

that 25fps of lose must start after a certain point. Question is, where?
