    I wanted something that looked different from all the other thread protectors and I found it. The threads are nicer than any other I own, thanks again!

  8. Spencer M.

    The Glock modification space is pretty crowded and Blacklist continues to standout for me in terms of quality and aesthetic for the price, but it’s really the customer service that keeps me coming back. Don’t hesitate to get in touch w them if you have questions – they can really hook it up assuming you’re not a dick.
