Anyone have any experience with Gorilla Machining 9mm barrels? At 90$ their price is looking pretty attractive.

I'm guessing that's a no.  I'll have to try them out and make a review.

It looks like they're made by ER Shaw.

Let us know what you think.  I'm still trying to decide on a barrel for my AR-9.

I have one.  The machining on the flat faces near the chamber were rough.  It had feed issues until I polished it.  Now it cycles without any issues with glock mags and maybe 1 out of 100 rounds has a failure to feed with my 33 round korean mags.

Pass.  I had one that gave me all kinds of issues, including a mystery thread pitch.  Check with Mad-Machinist and get one of his barrels.

+1 on Mad-Machinist/Macon Armory. Give him a call and see what he has available.

Macon armory is what you seek. Great guy, great prices, great products. Hands down best customer service I've ever had.

I have blanks on the floor.....and 5 inch barrels in stock...pretty much sold out of everything else.....if you can tell me what you need I can pull a blank and manually run one for you if you are in a hurry, The 5 inch barrels we have in stock are nitride coated.....the manually made one would be 4140 CM with cerokote. Hope to be running 9mm in a couple of weeks......16's 8.3 and probably 5.5 inch......just have a large order of 45 barrels we are in the middle of making.

Edit:  Found a complete 16 inch 9 mm upper today..........and a dozen 11 inch 9mm barrels.....

Just got mine, haven't tried it yet. But now I'm kind of iffy to, considering it's got a tirant 9 on the end of it.

If you have dial calipers....measure the wall thickness of the muzzle threads from the groove to the OD thread surface....if it is within a couple of thousandths on all points you should be good to go.....
I'd also measure the breech end from OD to chamber wall.......in at least 4 places 90 degrees apart. It should measure within a couple of thousandths on each as well. Also measure the protrusion of a loaded round....it should be .130 to .140 from the breech face....assuming your bolt pocket is .125......and it should be with the bolt you have.
