What does it mean when a barrel is pinned?

A pinned barrel refers to an actual steel pin that goes through the frame and a notched rear portion of the barrel, and it was originally intended to help anchor the barrel to the frame in both magnum and some non-magnum revolvers.

Are AK barrels threaded?

Many AK-47 rifles chambered in 7.62x39mm use 14x1mm LH (left hand) threading. The threaded barrel extends beyond the sight post.

Can you silence an AK?

Rarely is an AK thread pattern readily available in your standard fare silencer, and there’s no shoulder to speak of for a silencer to seat against. AKs are already so overgassed; adding backpressure from a silencer just makes it a heavily recoiling mess. And yet, it can still be done.

Can you cut an AK barrel?

You will need to file a BATF Form 1 with a $200 check and once you get the tax stamp just cut the barrel, file end flat, recrown 11deg. add a touch of cold blue and screw on the muzzle device. You can rent the crowning tool from dinzag arms.

Are AKs Overgassed?

And as far as AKs being over gassed even Jim Fuller, the premier AK builder and owner of Rifle Dynamics, says all AKs are over gassed. So I started looking for ways to reduce the gas impulse, bolt speed and, most importantly, felt recoil.

Does AK47 have silencer?

SAI manufactures a silencer / suppressor for the AK-47 Kalashnikov assault rifle chambered for the 7.62 Russian cartridge. The SAI KSS Silencer / suppressor has been developed with the purpose – not just to reduce the noise of the AK47, but also to obtain better overall handling of the AK47.

How does a pinned and welded gun barrel work?

This is usually done by drilling a small hole in the muzzle device (if it doesn’t come with one already), driving a pin into the hole so that the device cannot come off the threads, and welding that pin in place. When you see someone mention a “pinned and welded” barrel, that is what has been done.

How big of a barrel do you need for a SBR?

NFA laws being what they are, a rifle has to have a barrel of 16″+ to not be considered a Short Barreled Rifle (aka, SBR). That rule is oppressive and arbitrary and dumb, but we can work around it. The US Army uses 14.5″ barrels on their M4 carbines. They can do this, because they are working for the government.

Can you change the muzzle device on a pro gun?

The issue with this concept is that the muzzle device you choose at purchase is literally the only one you can ever have on this barrel, as it is literally part of the barrel. That means swapping to a flash hider instead of a compensator (or vice-versa) requires a whole new barrel.

What happens if a flash hider is pinned and welded?

If your flash hider is pinned & welded, you have to pay someone to get that handguard switched out, and if you don’t replace the barrel entire barrel, you’re either paying that guy to re-weld that flash hider back in place or filing SBR paperwork. Pinned & welded a QD suppressor mount to your barrel? That’s not a terrible option.
