My favorite AR15 lower. It has the best controls layout of any lower. And the online shopping experience and fast shipping was great!

Rooftop Defense is an excellent vendor. They ship very quickly and keep you informed from order placement through delivery.
The LMT lower receiver is great. The controls are perfectly placed. It is my go-to for an ambidextrous lower.
