Blacklist Industries Ultra Match Barrels are some of the most precise match grade barrels in the industry and come fully equipped with our NO BULLSHIT LIFETIME WARRANTY. Each unit is precision machined from certified 416R stainless steel for superior strength, longevity, and durability. Critical tolerance requirements and multiple quality-control checks, along with an advanced broach rifling process guarantee outstanding accuracy from each and every barrel produced.

The strategic advancements in Blacklist’s design provide benefits such as a tighter lock up and significantly better fitment, while also achieving a substantial increase in accuracy in comparison to a stock/factory barrel. The propriety fully supported chamber makes Blacklist barrels compatible with all bullet materials and +P ammunition. This feature reduces the risk of dangerous pressure spikes that are commonly found in stock/factory barrels.  

The barrel also features a recessed crown at the muzzle. The recessed crown preserves the barrel’s outstanding accuracy by preventing the edge of the rifling from being exposed or damaged in any way that can affect the rotation/spin of the bullet. Eight column flutes are added at safe depths which provide a custom look and finish to the barrels. This is a replacement/drop-in barrel, no gunsmithing required!

  1. Sam

    These guys are the real deal… do not bother with other sites that are subpar. These guys get your order right and on time the first time. Customer service is 100% the best service I’ve recieved from any company even beyond gun parts. Your barrel comes in a beautiful box… with extra stickers, velcro logo and foam to keep in place. They keep you updated every step of the way from delivery to delivered. I don’t normally write reviews for anything… but I’m writing this for the sake of the company owner reaching out to me. Absolutely, solid these guys are. 10 outta 5 stars. Thank you for your American engineering and holding nothing but the best quality for us patriots. God bless.

    Slick looking GLOCK 43 barrel…haven’t had a chance to shoot any rounds through it yet, but if it shoots as well as it looks and fits, it should be perfect. Super fast shipping too. Very satisfied
