LMT lower is awesome as usual but Rooftop Defense is even better with how fast they shipped and the goodies that came with makes me want to buy more from them again.

LMT is cool but rooftop is top tier as far as COMMS, the products they keep on shelf and they got some humor so will definitely be shopping again

Another great product provided by a great company. The availability is awesome and Sol is excellent at providing top notch customer service. The lower itself is high quality and very thought out with the controls. By far, it’s amongst one of my favorite ambidextrous lowers out there.
