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!

    Have only installed at this point but this was effortless. Wanted a bit of improvement in potential accuracy & ability to add a can to those threads. The chameleon finish was just to add a bit of color and separation from the crowd. Can’t wait to send some rounds down range soon…and get the can order started.

    I have a Gold Tin Blacklist barrel in one of my G34. I have fired approximately 12,000-15,000 rounds through it so far and have had zero issues. I plan on building another G34 soon and will definitely be getting another one.

    Can’t speak highly enough about this company and my barrel. Not only does it look great, it works amazing as well. Everything down to the way it’s packaged is quality. Hell even the email notifications you get after purchase are good for a laugh! Such a great addition to my G43! I will definitely buy all my future barrels from Blacklist

    It was quick she came to my door all dressed in Black. I was beside myself with her beauty and style. When I handled her she slowly slid through my fingers. I could not resist myself, with anticipation I took that barrel and slid it inside and was very surprised at such a tight fit. You guys rock thanks again for the great product!

    Outstanding Barrel, pricey but very accurate installed in a g26 Glock . Love it

  8. David B.

    I haven’t had a chance to use either one yet. Its my curse. An evil gypsy. As soon as I over come this, I’ll get to an indoor range and try both barrels, one for my G19x and the other for my G26. I only have one question. Can sliver bullets be used in these barrels.
