11.5 Middy for dedicated suppressed use

[Beemill2142]

Say I’ve got a 14.5 middy with a gas port at .080. I know Faxon has a 11.5 middy with a huge gas port but I have no intention of using this without a suppressor. Say I chopped the 14.5 to 11.5 and used it as a dedicated suppressed barrel. Would it run with the .080 gas port? I think so. What say you?

[Zane1844]

I think .80 will be pretty gassy with suppressor. Does it have to be a middy? Check out the Sionics ERGP barrel, it's meant for dedicated suppressor use. I believe their port is smaller than .070

[Beemill2142]

It does. Instead of buying a new barrel I’d like to just have a smith chop the one I have now. As I understand it, Faxon’s middy was like a .1 port diameter. Now that thing was built to be ran with or without a can.

I should mention that I will run an H2 buffer with an adjustable gas block.

If you are running 100%suppressed I would just get a gas block insert from Black River tactical. .70 should be good, maybe even a little smaller. Less moving parts than an adjustable and cheaper

That actually might be in the ballpark.

Depending on the suppressor mount, consider threading the muzzle 5/8-24.

[Beemill2142]

Yeah I’m not opposed to a BRT insert, I just already have an SLR adjustable block that may do the trick.

Yes. Strongly consider 5/8-24. .080" with a mid & 11.5" barrel should be pretty close and with the AGB...

Suppressor is a YHM Turbo which uses a 1/2-28” mount. I’m anxious to get my eForm1 back soon so I can have this bad boy chopped - I’m pending FBI now. :/

An adjustable gas block only helps you in one direction. Are you able to open the gas port yourself without the chance of destroying it if needed?

Sending it off for gas port work may erase your cost savings over getting a barrel known to work the first time.

Do you mind explaining why you suggest that threading? Not questioning your wisdom, just genuinely interested.
