This listing is for a completed Aero Lower Receiver. It features a Texas Edition Aero lower, Geissele G2S trigger, Geissele maritime bolt catch and SBA3 brace. Because of this brace, you can put any length barrel on it and have it be legal (AS OF THE 10/11/2024). The rest of the parts are just standard milspec parts besides the ambi safety. This configuration has seen about 500 rounds and has zero issues. I’m selling because I purchased a new lower for my BCM upper. I will send any photos and answer any questions at your request. Located in Cypress. Thanks for viewing!
