9mm AR barrel

[G19G26]

Anyone have a lead on discounted 4" to 6" 9mm AR barrels?
Getting bored, so I want to put together a new upper.
Thanks

I have a ballistic advantage 5inch barrel thats been reliable/accurate. It is around $100 right now on there website.

Ive heard good things about Spinta Precision 9mm barrels too but no personal experience. They seem to have one in stock for around $80 checking the website.

I have a Spinta Precision barrel and BCG. Works just fine. Back in the day folks had issues with BA 9mm barrels because of the feed ramp geometry on the barrel extension. I don't know if that's still a thing.

I have a BNIB Faxon barrel, only to find out it has 1/2x36 thread a year after I bought it.

My 10" BA 9mm barrel wouldn't cycle hollow points until I installed a Taccom feed ramp in upper. I spoke to BA a few months ago to see if they had corrected, but they hadn't.

I remember guys sending their BA barrels to Macon Armory and Foxtrot to have the barrel extension/throat re-profiled. But like I said, that's been at least 3 years ago. I don't visit the 9mm AR forums anymore since putting mine together. I remember they used to be tedious. Feed ramp geometry, BCG and buffer weight was crucial to get them to run properly

THIS. A buddy had weird extraction issues. Turns out the company shipped a 9mm carbine with a 223 buffer installed. Oops. Once he called it to their attention they quickly shipped him a proper buffer.
