Chopping a barrel

[LowSpeed_HighDrag]

Again, I am curious. What was your experience with those barrels? How did you have them set up?

Mine run just fine.

Bill,

Another reason for me doing this is it's only costing me $130 to have a barrel that's already headspace with my bolt cut down and have my new rail installed as well. A lot cheaper than the new barrel route and I know the gas port will be sized right for my application.

What MD/suppressor will you run? I'm curious as it pertains to the muzzle thread options.

Curious - leaving gas port as is?

No. New gas port .067

No. New gas port .067

That's a big port for dedicated suppressed use. My 10.5" is 0.047" and I've put a ton of trouble-free rounds through it. Kinda wish I had gone with 0.042" sometimes.

Pistol gas?

For most cans and 5.56 pressure ammunition, you would not want a .067" carbine length gas port for dedicated suppressed only use for a 10.x"-11.x" AR.
For suppressed only use similar to the above with a regular M16 chamber, throat, and bore, most would not prefer the .042" gas port.

Excellent pic, thanks.

It's going in the "I told you" folder.

Sometimes a picture is worth a thousand words...

Now, to get manufacturers to make 5.56-sized muzzle devices threaded in 5/8-24...

It's not just 5/8" threads, but how the devise registers to the barrel. There's a few paths that we can go down for this.
