    More Stuff than you think (than shown in pics). Comes with grip too so its def worth the price. As far as organization goes, i wish each sub kit of parts was bagged separately. Must use the Instructional Videos to identify the parts needed for each task. Overall very pleased!

  2. Kurt H. (verified owner)

    Excellent finish
    Considering today’s market place outstanding value

    The parts fit very well on my Angstadt lower and the trigger had a nice pull on it, too!

  4. Tim O. (verified owner)

    Excellent quality. Very complete. Even included a pistol grip. Outstanding value at any price, but even better at the sale price! I will definitely order from them again.
