    It’s a thread protector. Not much to say about the item itself, it’s quality, but the customer service and the awesome shipping notification sold me on repeat business.

    Top quality materials and products from Blacklist! Purchased a threaded 9×19 barrel for my G26 and can’t be any happier with my purchases! Will be using these guys for any of my customizing needs in the future no doubt!

    I’ve had the barrel for my m&p since the first drop of the tin(gold). Love the barrel even though I was constantly fighting the thread protector. Some how I held on to it untill a month ago. The next day I hopped on the site and was able to get a hold of a new threaded tip cover and it looks a lot better than the original. Plus the addition of the orings to help keep it frozen in place. close to 1,000 rounds in so far and no movement issues. I would buy it again considering the price point and I received it in less than a week. Keep evolving blacklist, you guys are on the right path.

    Great products will definitely be coming back for more

  11. 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.
