Glock 23-9mm Conversion Drop In Ultra Match Barrel


(854 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!

Best On The Market!!!

First off I purchased my Glock 23 gen 4 because of the barrel swap capabilities…that being said, I have literally looked at different barrels for weeks now trying to compare them, and trying to decide which looks the best to me, BUT also which I believed to have the best quality as well. Watching reviews and trying to decide damn near drove me crazy, and with so many things being out of stock and on back order I almost just gave up and said screw it….but for some reason I got lucky enough to find this TIN Gold Barrel and felt like it had to have it. Only thing that stopped me for a second was the price point. So I started looking at the reviews and with as good as they were I decided to pull the trigger and purchase it. I COULD NOT BE ANY HAPPIER WITH THIS PURCHASE!!! First off the shipping was very fast, ordered it Monday and got it today (on Thursday). Secondly, the packaging was impressive to me! I’m not going to spoil it for other ppl but it didn’t just come in some cheesy cheap *** plastic tube type container like all the other conversion barrels I looked at came with…it came in quality packaging! Not some BS!…Last but not least, it looks AMAZING AND FITS FANTASTICALLY! fits very tight and Shoots great! This barrel may not be cheap, but the quality is there and it looks like it too. You will NOT BE DISAPPOINTED IF YOU DECIDE TO BUY!…all in all it’s ******* Amazing in every single ******* aspect 💯 💯 💯

Great quality, great product, and really surprised by the gear and case.


To say how pleased I am with my purchase is an understatement to say the least. This is not a gun barrel as mush as it is a work of art! The actual color of the Chameleon is simply breathtaking and is perfect for any modern museum. The fit was perfect, and shoots dead on accurate. Do yourself a favor and don’t wait. You’ll be glad you didn’t.

Great company! Really good experience and some super sexy barrels.


The site is easy to navigate. The customer service is awesome and hilarious. The quality of the chameleon barrel blew me away. Dropped it right in, shot a couple hundred through it and it ran flawlessly. I'll be purchasing another barrel for my G34 soon. Great work guys!

Outstanding quality!! You are getting what you paid for!! The fit and finish was perfect. It was as described, and my best upgrade for my glock so far.

Build a Polymer80 Glock 23 since the tac team I work with uses .40 still, but I much prefer 9mm when I carry on my own. This barrel was truly a drop-in with no modifications required, beautifully finished, cycles in my G23 without a hiccup, and is more accurate than the stock barrel. Very happy with my purchase and plan to purchase for any future builds as well (with they made a conversion for the subcompact).

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. **** 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
