Review by Mark R. on 28 Apr 2024review stating Airborne Arms for the Airborne in you.
Fit and finish was fantastic. They are definitely mil spec. I just had to finish up a couple uppers that were sitting around. I had never heard of them but that 's not new. There are lots of start ups trying to get into the business and this is one. Thanks for making them available for a fair price too.
Review by Timmie W. on 25 Dec 2023review stating You cant beat these for
You cant beat these for the deal ranier has them, they are well machined 7075 and i cant say anythng negative about them tho a cple of my friends dont like the finish they say its gritty me personaly i like it i often use the magwell as a grip and the texture of the anodize helps keep a firm grip. Fast shipping as always.

Snagged a couple of these on a BOGO offer and it was worth it. Other than that there is nothing super special about this lower. Everything looks to be what you'd expect when purchasing a stripped lower. Everything fits tight and I didn't notice anything that stood out.
