I have a 1980s AR-15 from an extremely well known Connecticut manufacturer that I was going to use a suppressor on. After removing the flash hider, I was utterly flabbergasted to see the muzzle crowned off center from the bore axis. I had always been perplexed that the rifle grouped poorly with all ammo types and as a result, it was my least favorite rifle to shoot. I ordered the Brownells 11 degree chamfer tools and some Tap Magic cutting fluid and re-crowned the muzzle. Point of impact shifted 4 MOA and groups shrunk to about 1 MOA with some ammo producing sub MOA. Now this is one of my favorite ARs with a factory carry handle. Thank you Brownells!

You guys have great videos. I've started to remember a lot of things my Grandfather told me as a kid about re-crowing barrels and other things. His brother owned a machine shop and used to modify a lot of firearms for hunters and the police. I was unaware that re-crowning was a process I could do myself. Thanks.

You make it look so easy. Appreciate the Tech Tips!

Wow, you guys knocked it out of the park with such a great tutorial. Why can't others do the same. Thanks a million.

Never thought of doing this at home. Always figured I would need a gunsmith with a lathe.

Most helpful videos and great to watch.

Thank you! I have a M1 Garand to re-crown, since the Muzzle Grade is a 3 and with dings, it is all over the grid. I'll be getting this from you guys soon.

That was great. I'd love to do this.

Perfect, thanks for the informative video. Now to spend some money on your website!

I thought he was joking when he pulled out the hack saw, but I guess the tool that inserts into the bore cleans everything up. Makes it look easy.

Brownells is such a good company. I try to buy from them as much as i can.

Think of it this way... the LAST thing the bullet touches before leaving the rifle is the bore at the muzzle. An imperfection there (more than any other place in the barrel) affects accuracy. Even a microscopic flaw at the bore / muzzle causes the bullet to deflect off course. A good recessed crown by a proficient gunsmith is CRITICAL to a rifle's inherent accuracy. SSG.

Are there radius tools for an octagonal barrel or would this one work? I am building a muzzle loader and would love to chamfer the corners of the barrel. I like the chamfered look much better than the plain square all the way across look.

Thanks. Are there advantages to either the 11 degree or 45 degree or is it just a cosmetic preference?

drill press and some make shift tools you can turn some brass down . or just make a clay mold and poor it ,,, then polish it up in the drill. / be just as good as anything they put out, save some $ , there's junk brass all over this country its just knowing where to look for its .. out door plumming mostly/

Very helpful, and very indeff also.

I would be a proponent of just a simple file-down (3:05). The outside contour of the barrel edge wouldn't affect projectile exit much anyway. Besides, I would not want to risk a screw-up of the inner chamfer/crown.

I just took a tremal with some fluid film and with to town on 2 of my rifles worked out great

That facing tool is genius!

All this stuff needs a restock ASAP!

Great information thanks

Great video!

I just cut and crowned a barrel on my personal.22lr, my second year gunsmithing, I plan on cutting to 90 and putting threads on later, but my crown is good, I already reblued the barrel, but on one spot it's not quite perfect. As long as my crown is and it shoots straight would it be ok to leave a little spot a few degrees off....

It’s probably help if you held the drill inline with what you’re using it on. Ouch.

Haha, yeah in a lot of places this is a felony, in others you have to ask permission half a year in advance and pay a $200 tax (and ask the government for permission way in advance every time you cross state lines) just to repair your old barrel. I’m sure our founders who executed their politicians for much less would pay that $200 on top of their tea tax right before blowing off some heads with their newly shortened sawed off musket. But you can’t even legally repair your barrel in many states so even paying the tax and putting your name on the dog execution list isn’t legal to comply with the game of tyranny.

how is a hacksaw and file a better option than using a proper lathe?

The crown is not the entire face of the muzzle, the crown is the exact edge where the rifling ends at the face of the muzzle.

I am amazed that the barrel steel is so soft! The hand chamfer and a hacksaw blade cut through it like butter. That’s amazing to me. I would think barrel steel would be somewhat hardened. I’ll have to admit, I do not look at my Browning BAR with as much respect as I did before. And where is the proof that Muzzle profiling is not just for aesthetic’s, anyway??

@five5105

Жыл бұрын

Barrel steel is most definitely hardened, it's just that the cutting tools are made from harder steel than the barrel. Barrels aren't super hard like the cutting tools because containing tens of thousands of pounds of pressure is not exactly safe with brittle steel lol. Using lubricants like cutting oil helps smooth things out a lot too.
