The AERO Gen 2 stripped lower receiver is the perfect base for your custom AR-15 build. Machined to mil-spec dimensions, Aero lowers work with standard AR-15 components and ensure the highest quality with a correct component interface. The Gen 2 has improvements such as nylon tension screws that allow for a tighter fir between the upper and the lower. The Magwell size has also been increased for easier insertion of magazines and a sleeker look. The lower is machined from 7075-T6 forged aluminum and has a black anodized finish.

I foolishly traded my previous Glock 20, and was wanting to replace it. Then, 2020 hit; and I couldn’t find a Glock of any kind, anywhere. 2-3 times a week, I’ve checked Firearmss’ website, looking for another Glock 20. Today, that perseverance paid off! Firearmss not only had one; but they had one in the color I wanted! Firearmss is my ‘go to’ gun store.

I love buying here and I cannot wait to buy guns I wanted a non ported barrel to replace the ported barrel. The ported barrel is way too loud.

It’s getting very difficult to find gun related items with our country in turmoil. I am always looking for Firearmss to help me find what I need.

Being a TBM really has perks and I am loving it. I thought I missed something I really wanted. Being a TBM not only put in the position to purchase the item I wanted, I was also able to buy it the way I wanted too.
