    Absolutely love it, awesome lower and a good price. Also very helpful service from Rooftop Defense. I will def be buying more from this sight again… and again.

    Best complete lower I’ve owned! FA cut. Best feeling milspec selector although I switch it out for either a SOLGW Quick or Radian 45 degree throw. I’ve never been disappointed with the quality of SOLGW freedom blaster parts!!!
