Previously Pinned Barrel - Ok To Use?

[hyemb350]

Hi all. Need some help figuring out if a barrel is still ok to use. A compensator was previously pinned & welded then removed. The hole is just in the threads and did not make it through to the bore. Is it ok to reuse? Thanks in advance.

Yes it's absolutely fine to use. That pin/weld dimple is fairly normal in depth, bottom of dimple should be right at the root of the threads.

Agreed. You're good to go. There's lots of meat between the bottom of the pin hole and the bore.

Gtg! Run it!

What’s up with the two different threads?

it looks like a cz scorpion barrel. CZ uses a 1/2-28 thread followed by a larger weird ass (18x1 metric) thread that nobody else ever used. More bizarre czechnology.

One of those quick change brake/silencer set ups?

Thanks everyone! That’s what I figured but thought I’d double check.

92G is right, it’s a scorpion barrel. It’s a bit of an odd setup. The larger thread is for the barrel nut that holds the handguard in place.

Are you just going to shoot it with out the muzzle device?
Looks fine to me. Even if it went all the way through to the bore it still would be fine. You just might have crud blasting from the hole. I have run my AR/M1 Garand with the gas port “exposed” with no issues. Other than single shot….

So is this pin and weld for compliance purposes ?
If so why did they only pin and weld the barrel nut. If done by CZ because they know the barrel nut comes loose?

Looks like you could freely remove the brake

Thanks. I’m putting on a different compensator.

No the compensator was pinned, not the nut. I want to put on a different comp then pin and weld it again.

I need to go dig into the safe and get out my scorpion, I swear my barrel looks nothing like that

The factory nut and comp go on the larger threads

I believe at some point they changed the barrels. I’ve seen barrels with just one type of thread.
