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.

As advertised – As advertised prompt response and service
I recommend MidState! – I have uppers from MS in 5.56, 7.62×39, and 300BLK. I really like them all. I got them all as “grab bag” specials with a few custom tweaks. They are all different but all great, I recommend MidState to everyone I hear who is contemplating an AR build. But my personal favorite is my 300 BLK build, it’s also the most customized. But the folks at MS are awesome, they build and ship fast, and are super priced.
Exactly what I was hoping for! – Amazing product with great quality and customer service! Added the adj gas block, and they installed it for me and even gave me a free koozie.
Perfect and high quality – I have a 7.5″ for .300 Blackout, but the floating M-Lock and barrel end to close to put on a can. I saw this deal and figured why not have 7.5″, non-suppressed and a 10.5″ suppressed to change between. This was the perfect idea, and MidState was the ideal match. Now I am rocking and rolling with the best of the best.
Amazing service – Thank you for amazing service. I put down some preferences on the order not expecting them to come true but you guys sent me exactly what I wanted. Thanks and upper looks great.
