    Good luck!
    I couldn't find a .40 barrel but there are a lot of 9mm uppers.
    I bought
    Davidson Defense Assembled 9mm Rifle Upper - 100% Made in America $159.99
    Tactical Shxt Billet 9mm 80% Lower (C-9) -for Glock Style Mags, $109

    Found a 9mm BCG on sale, $130

    If you're open minded to an ar 9mm build, you would get the same results and an easier time finding parts.

    If you're open to other items costing less, there's a lot out there. Heck, I see an ad in your area for a sub2000 9mm for 400 bucks. Or maybe do what I did and go find a Marlin model 9. Great sturdy working rifle.

    If you're hell bent on a 40 ar, I look forward to seeing you share your build and post some pics!

    I can understand not wanting to add another ammo category to stock but the reality is it will be quite a bit cheaper to build and far cheaper to shoot a 9mm AR. Sounds to me like a good excuse to add a 9mm Glock to your pile and then have a pair that share magazines :D

    Excellent application for a 300 blackout. Either buy ammo or buck up and load for it. It is easy to handload and you could probably pay for the dies and components with the savings you get by not paying for a rare caliber upper. Ballistics will be much better with 300 blk as well.

    If you are dead set on a 40 sw, it does look like Rock river arms offers a complete 40 sw upper for $640 with 20% off that right now.

    I am with the others on building a 9mm, it will be far easier to get good parts and they will be cheaper to boot. Since it sounds like it would be rarely used anyway you shouldn't need to load ammo for it, and 9mm is cheap.
