  1. D_J –

    Solid, good attention to detail. Crisp “SAFE” and “FIRE” nice magwell, and the shelf is a great touch to give you an idea of the kind of fit you’ll have with your upper. before you mill a thing. This is a great canvas to create your next build.

  29. lew –

    acceptable good quality receiver.

  30. Troy Wright –

    These are made great. I have had other lowers a little off which it did not affect the function but does affect the look once completely built. These were perfect, and that is the reason I bulk order them. I will only use AAO lowers for my custom builds.

  31. Philip Weiser –

    Lowest priced raw lower I found. looks good and was easy to finish. May buy another one. Waiting for black one to get in will order one next.

    The fit and finish is awesome, ‘‘tis fit perfectly to all the different uppers I own. Very crisp and clear engraving as well. l will be buying more.

  48. Zach Bjerke –

    I’m really impressed and it would have gotten five stars if there was an option to have a lower with no “Safe” “Fire” markings are all for those of us making clones. But the quality and fit are great and I would recommend this product anyways.

  49. James –

    Arrived quickly. Good quality lower.

  55. Angel G. –

    Really satisfied with this item , fast shipping as well

  56. Ryan –

    I’ve gotten several receivers from AAO, both 556 and M&P 9mm. The machining has been great same with their shipping and their prices are the best I found. I highly recommend this company

  57. Anonymous –

    These are machined to a very high quality. Ready to paint or coat. If anodizing I would suggest polishing a little first. Fit to multiple uppers is perfect. The tension screw is nice as well.

  58. Eugene H Peruski –

    Great product.

  59. Paul Caldwell –

    Outstanding

  60. Behind Enemy Lines –

    AAO is as solid as they come, that’s first and foremost. Great company, great products, and great service.
    I love these Raw 80’s, as I finish with Cerakote anyway, I’ve built a number of them and never experienced a single issue; no out-of-spec parts, no damaged parts, nothing. I also very much appreciate that they machine out the area of the rear takedown pin. Not all distributors of 80’s take this extra step but it makes things a good bit easier for us non-CNC’ers.
    I’m just a hobby-builder gun nut, and by no means wealthy, so cost and VALUE are important to me. With that said, I’m not aware of anyone who can reliably beat a price of $41 each!
    In closing I’ll offer up A word to the wise: If you’re not already using AAO’s 80’s sign up to be notified when they’re back in stock!!! And when they’re around ACT FAST!

  61. Rick –

    Always the best quality products from AAO for your project. I would recommend this company.

  62. TJ B –

    Great product. Great price. Fast shipping

  63. Keith G Coulombe –

    Exceeds expectations. Rear takedown recess a nice touch.

  65. Rey Parra –

    Wow, I can’t believe this is great quality lower is priced so well. Definitely made a lifetime customer out of me. Shipping so fast I got whiplash.

  66. Gary –

    Waiting to buy more when they come back in stock…

  67. Mike –

    Great quality, can’t wait to mill them out. Definitely buying more.

  68. Troy Wright –

    Doing my custom builds, I use these lowers exclusively. They are always machined perfectly and the tension screw is a bonus that I use to sell to my customers.

  69. Gary –

    Great for the at home hobbyist.

  70. NGY Customs –

    Very nice casting, looks clean and precise. The threading also looks great. Looking forward to the build.

  71. Bill Story –

    Made of good quality and machining. I see no issues for them.

    I have a few other brands of 80% forged lowers and these from AAO are by far the best in both being true spec to flawless finish

    Great craftsmanship. I recommend their parts to everyone.

    Great lower, the finish is fantastic, the pricing was awesome! Great quality product, will be buying more.

  80. John, Mustang Arms Company –

    By far and away, one of the best 80% I have used. Their precision machining is true to spec and the fitment mates with uppers of all types and manufacturers like they were made together.

  85. George –

    I’ve dealt with these guys on a couple of purchases and they are super to work with. I orders the wrong engraving through my own error and they exchanged them no questions asked. I will always be a customer. Thank you AAO.
