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.

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.

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.

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??
@five51052 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.
