    Very solid option for a mil-spec, complete lower. Finish, staking, etc is immaculate and comes with their awesome qd endplate that is similar to the FCD. Trigger was all right, but I have to admit that I’m a snob and threw in a Geissele. RooftopDefense also fantastic per usual.

    Just a great boring milspec lower sold by a high tier organization. 5 stars for Rooftop for being the goat of online pew shopping. Best customer service, best stock, fast shipping, and always a good time opening their boxes!

  3. Jason (verified owner)

    Solid lower. Will last forever, comes with a decent trigger and a nice grip. For the Rooftop price it’s the best value lower out there.

  4. Tim Robertson (verified owner)
