Gunsmith for target crown

[Redshirt]

I’m looking for a gunsmith to change a threaded barrel into a target crown barrel. Who does this in Westchester or nearby and what should it cost?

 

[Mosinitis]

What's a target crown barrel and what does threaded muzzle has to do with it?

 

[tony]

I'm thinking what he is after is having threads removed and an 11* target crown cut on muzzle end.

 

[Redshirt]

Yes, that’s it exactly.

 

[tony]

If you don't mind... What firearm? and what is present barrel length?

 

[Mosinitis]

I'm thinking what he is after is having threads removed and an 11* target crown cut on muzzle end.

Most if not all quality barrels with threaded muzzle will have recessed crown cut into them. One is independent from another. There is nothing magical about 11* crown. As long as the crown is uniform and undamaged the angle doesn't really matter for accuracy. Recessed crown is what counts to protect the crown. OP may have that already.

You should tell OP, not me. I know the purpose of a crown... and how to cut one.

Answer the OP's question if you know the answer...

I assume OP is reading this.

I suppose I should have mentioned that this is for an AR-15 upper. I’m trying to do a budget featureless build, and I’m realizing that this way might be cheaper than buying a non threaded barrel.

 

[tony]

your barrel needs to be over 16" after cut/crown?

I would just use loctite to glue on a thread protector. I know some people will tell you it's not enough. I will just call them idiots and leave it at that.

Red Loctite not blue

Red Loctite not blue

Green Loctite not red.

Yes, it would have to be 16" after the cut. I thought about the loctite / pin weld but I'd prefer not to go that route out of an abundance of caution.

While I agree that the ATF are indeed idiots, I'd rather do it right in case I ever have to use it and it's confiscated for inspection. You do it once and forget about it.

He is quoting a letter about a different law from an agency that doesn't have jurisdiction over the law at hand. There is an old Slavic saying: send a fool to a prayer and he will injure his forehead.

 

[Marine Cpl]

When state law doesn't define something, federal law is reverted to.

You do you. But don't go around telling someone asking for advice to take shortcuts. Any gunsmith worth his salt does it by ATF specs.

 

[Mosinitis]

Blue, red or green will work. Don't get it into the bore, leave the last few threads on the barrel dry.

You are not quoting a law. It's a letter from the agency that doesn't have jurisdiction and it's about a different law, which expired.

Look up the Federal law. It's in a US code that I can't look for at the moment. I posted it on another thread that we argued about previously.

 

[Redshirt]

Anyway, what I want to do is cut the threads off and crown the barrel. Anyone have experience with that that can suggest someone to do it?

 

[Calculon]

I don't know any local gunsmith. Give Scott at Collector a call - if he can't do it he'll probably know who can. Brownell's and Midway probably both sell the tools if you want to DIY.

 

[Acer-m14]

last i knew they can't have a gunsmith in court with tools to take it apart .. i'm sure Leo can't do the same in the field .. if it won't come off with just hands .. your good

but who gives a fk .. all the gangs in the US have the fun toys ..

While I agree that the ATF are indeed idiots, I'd rather do it right in case I ever have to use it and it's confiscated for inspection. You do it once and forget about it.

Do you really think that they check a weapon's operability in the courtroom?

 

[GUNSICK]

Find someone with a lathe and throw them a couple bucks to remove the threads and re crown.

The thought of another legal ar15 gun owner in this state makes me happy. If you cover shipping, I will cut and crown it for free (needs to start life as at least an 18" threaded barrel).

Attached is a picture of my handiwork. If interested, shoot me a PM brother.

Awesome @Runner99 ! Good man.

 

[Redshirt]

That is a generous offer. Thank you. I’ll have to start shopping.

I bought an upper from him and can attest to the quality of his work. You won't be disappointed.

Bought a rifle off him a number of months back myself. Stand up guy, highly recommended.
