300 Blackout Ar-15 Pistol length ‘Grab Bag’ upper. Sometimes we receive some cosmetically blemished parts, or a customer might back out on an order, or we may have leftover gun-show inventory. This is an assembled upper (option to add BCG / Charging Handle) that will come with a free float handguard style of your choice! Picatinny Quad Rail or Slim M-Lok! Lengths and rail type may vary. The receiver itself might be forged or billet, and may or may not have dust cover / forward assist features. The upper/barrel will be functional (shootable), but may just have some cosmetic blemishes, or something small like the dust cover opens if you look at it wrong. Quad rails may fit tight on certain attachments like Magpul. If you aren’t picky and just want a working upper at an advantageous price, this deal might be for you.

Midstate is the BEST

There's a lot of places to buy parts, but none that give you the value Midstate offers. And somehow, to my door in 2 days every time! My go to, every time.

Looks tough

Got my upper build and it looks sturdy, waiting to get out on the range to test it out.

Interesting purchase!

This is my first AR upper purchase. The mlok handgaurd is beautiful, the upper is a lefty which is awesome, and a NiB bcg. The barrel appears to be a BCA heavy profile. Shipping was fast and great customer service via text! Can't wait to try it out on my psa lower (which took x3 longer to ship).

Barrel bore Looks a bit rough after cleaning

Barrel bore Looks a bit rough after cleaning. It was dirty, so this may just be a bit or rust. I have not fired the gun yet and this may clean up with a few rounds through it. Otherwise, fit and finish was surprisingly good.
