(892 customer reviews)


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!

    Dropped into a factory cerakoted frame and slide and required a bit of cycling to break-in and function reliably. I was anticipating the issue so no big deal. Also had to modify a Crossbreed reckoning holster to accept the slight increase in barrel length, but again, no big deal, just some items to consider.

    It’s bad ass from a bad ass company PERIOD!!

  3. Jeff (verified owner)

    Item is such high quality and beautiful finish ????!! I’m only buying barrels from here from now on!!

    This is my second Blacklist Industries barrel (G43x & G19). These barrels kick ass! The fit and finish is perfect and can improve even my accuracy. If you are on the fence about buying one, get the fuck down and drop some coin. It’s worth it.

    Bradley, Thank you for the review. We would like to take a moment to address your concern. Once the slide is installed onto the lower/frame, the guide rod disengages from the barrels notch and sits on an area in the frame that it is designed to be placed. It no longer sits on the barrels notch for the guide rod that it would prior to install on frame. This design was done by Glock intentionally and is a widely unknown fact in regards to overall design. You have nothing to worry about in this aspect. Hopefully this puts you at ease. Thank you again for the support

    I like the barrel but the only downside is my guide rod does not like to stay sitting on my barrel. Every single time I rack my slide, the guide rod moves up out of its spot. Not sure why that’s happening. Seems to shoot fine and cycle fine. Just kinda bugs me. Other than that, this is a very high quality barrel. Loved the packaging and the stickers. Will update my review if I find a fix to this. Just want it to stay put.
