Blacklist Industries Ultra Match barrels are some of the most precise match grade barrels in the industry.  Precision Machined from certified 416R stainless steel bar stock for superior strength and durability. Critical manufacturing tolerances, multiple quality-control checks, and an advanced broach rifling process allows us to guarantee the exact same accuracy from each and every barrel while also achieving greater accuracy over a stock barrel.

Eight column flutes are added at safe depths which provide a custom look and finish to the barrels. Our barrels also feature a recessed crown at the muzzle. The recessed crown preserves the barrels accuracy by preventing the very edge of the rifling from being exposed or damaged in any way that can affect the dynamics of the bullet.

Our fully supported match chamber is compatible with all bullet materials and +P ammunition. This feature reduces the risk of dangerous pressure spikes that are common in most stock/factory barrels. This is a replacement/drop in barrel, no gunsmithing required!

  1. Sam (verified owner)

    This barrell is legit as well as the company it comes from👍 The fit and finish is superb. I recently purchased the graphite barrell for my m&p 9mm 1.0 4.25 inch barrell. If your on the fence on getting one, pull the trigger and you won’t regret it.

  2. Brian (verified owner)

    Just received my barrel…AMAZING!!! On looks alone, this is a beautiful barrel; not a flaw anywhere, and the Chameleon color is insane!
    Can’t wait to shoot it! Thank you Blacklist!!!!!!

  3. Corey Sheppard (verified owner)

    This barrel is a perfect fit for my m&p 9. I applied a very thin coat of rem oil, went to range and put about a hundred rounds through it. So far, so good. Also liked blacklist customer service and their communications were not only prompt, but absolutely funny (nice touch).

  4. Corey S. (verified owner)

    Received barrel today and dropped into my M&P9 1.0 4.25″ and it was a PERFECT fit. Applied a little rem oil and worked slide and tested magazine for feeding issues and there were none. Fired a couple of mags through it with no problems at all. The added bonus is it looks really, really cool. Also really liked emails from Blacklist. Really, really funny and original. Delivery time was great and overall great experience.

  5. Brandon Barchenger (verified owner)

    Talking to Caliber Royale on Instagram about his blacklist barrel and he said nothing but good things to say about, it and said I would love it. And I got it installed it and it looks really good. Going have to take it to the range

  6. Gene R. (verified owner)

    Ok, I tested out my barrel today and am very satisfied. Accuracy was spot on and way better than the stock barrel. The lock up was definitely much tighter. Overall I’m glad I pulled the tigger (pun intended) on this barrel after doing my research. Perhaps my only critique would be the fit at the muzzle end. There is a minor gap between the barrel and slide, but this does not affect the performance of the barrel.

  7. Zechariah Kehoe (verified owner)

    So far so good! Seems to have fixed S&W’s locking/accuracy issue with their stock barrel. However, I noticed that the “Silver” becomes more satin and “flat” on the breach end rather than a high polish. Purely cosmetic but I was hoping for a higher shine throughout the entire length of the barrel

  8. Levi A.

    Exceptional! First of all the customer experience is next level, everything from shipping speed to language in the communication. The barrel is the sexiest thing I’ve ever seen and makes my gun gain about 10 badassery points. I’ll eventually put one of these in all 3 of my guns and make sure my conworkers do too!

  9. James S.

    This company is outstanding! Their product is super high quality. Will order from again

  10. Steve N.

    I read great reviews of Blacklist and decided to give them a shot. Literally. They made great work keeping in touch with the process as there was an extended wait time. My barrel fits great and eats up all ammo I have put through it. On a side note. Fuck all the politicians in DC trying to strip us of our God-given rights of purchasing and possessing badass firearms. *chugs whiskey*

  11. Ben D.

    Fits perfect and looks bad ass. Going to buy another SW so I can buy another Blacklist barrel for it!

  12. Gaelan F.

    Was able to stretch the spread point of my shots from 12 yards to 15. Very good barrel

  13. Ryan P.

    Before I get to the product, the customer service from this company is amazing and if you read the fine print on the information they send you it’s hilarious. You can tell that this company is run by people that care about their product and not red tape. The barrel came as described, fits and functions flawlessly. If you’re looking for a barrel that’s rated for p ammo, look at these guys.

  14. steve s.

    Haven’t had a chance to shoot it because my slide is out for some Milling for an RMR but the machine work looks totally professional no blemishes looks awesome I couldn’t ask for more cannot wait to shoot it

  15. Grant P.

    It’s a great barrel, finish does wear off in normal spots but not a big deal.

  16. Jacob P.

    So overall blacklist industries was amazing… Great communication answered all my questions! The barrel looks and shoots amazing!! The only downside is the coating doesn’t last( Lifetime recoating ) but my firearms are tools…. not safe queens!! My guns get dirty and beat up…. train , train and train some more..YES I’D GET ANOTHER BARREL!!!!

  17. David W.

    Great accuracy and no malfunctions and the barrel works fine.

  18. Elijah H.

    The quality is a step above most and when they say drop in, they mean drop in and no fitting needed. Customer relation is some of the best I have ever received. thanks Blacklist for everything and will buy a lot more products. elijah

  19. Seth K.

    The barrel is extremely accurate and the finish is beautiful. I could be more happy with this barrel. It took me 10 weeks because of the lead time to receive the barrel but it wad absolutely worth the wait.

  20. Miguel h.

    Very well made barrel! Definitely would recommend them to anyone

  21. Christopher J.

    This is my second blacklist barrel. They shoot outstanding

  22. Bryant T.

    Great customer service and fast shipping!

  23. Mark P.

    The MP Shield barrel I ordered shipped quickly. Arrived without issue, and I got updates throughout the process, so easy to track. When it arrived the fit and finish was outstanding. Dropping it into the gun was easy, hassle and worry free. My Shield 1.0 has served me well and I’m not ready to retire my current EDC, but with the new 2.0s out I was feeling it was time for an upgrade. The new barrel certainly improved the looks and with a new trigger, it feels like a whole new gun. Thanks for being awesome. Keep it up!

  24. Zachary H.

    Great. Awesome company.

  25. Daniel C.

    Looks absolutely beautiful, fit in perfectly, can deff tell that its made with love and precision.

  26. Terrence B.

    Very happy with the barrel , nice finish and shoots great !!!!!!!!!

  27. Fred D.

    Still have yet to use mine because I got one for my Glock 19 as well. My first barrel was stolen from my mailbox. Blacklist was very kind to give me a great discount When I decided to order again. When I bought it the 2nd time I decided one for glock and one for mp. The gold barrel for my Glock shoots soo smooth without any malfunction. I prefer blacklist barrel over agency arms barrel. Put almost 1k rounds through it within 2-3 days at the range. The look alone was beautifully done. Shoots great with my custom agency arms Glock. I love my Glock but I have way more fun shooting my mp9 core ported. I just love staring at the box with the barrel in it. I’m going to unleash this mp barrel this weekend. I KNOW I will love it. I wish blacklist makes 5 inch mp barrels as I have both the 4.25 and 5. Awesome barrels and great customer service!!!!!

  28. Sean T.

    This barrel looks and feels amazing.

  29. Rob S.

    I don’t want to speak negatively about S&W, but when I received my Blacklist barrel, it made the factory barrel look like the machining equivalent to a “rough draft”. The finish and precision on the Blacklist barrel is outstanding. It was like upgrading from one of those old wood-paneled teevee’s from the 70’s to an Ultra HD 4K flatscreen in an instant. If you don’t order one, then you are not smart. So be smart. Be smart today. Buy a Blacklist barrel.


    Love the barrel , have had a lot of comments on the finish . Having a problem getting the action to close on a new magazine . Hangs up hard, have to slam the bottom of the magazine hard !

  31. Oscar S.

    I am very impressed by both the quality of the barrel and the service I got. I received the barrel much faster than I anticipated and they updated me along the process to let me know where my order was. I even like the packaging that it came in. I will definitely be ordering a barrel for my Glock next.

  32. Nolan S.

    Great product, performs, looks cool.

  33. Michael P.

    Great communication from the get go (funny emails by the way). Everything is just awesome, from the packaging, to the way the barrel looks (drop in ultra match for MP 9 1.0), and the fit was perfect! Love how the barrel looks through the cutouts in my slide too.

  34. John H.

    This barrel has all the features I was looking for with the added benefit of the TiN coating. Well worth the wait, knowing that quality wasn’t being sacrificed.

  35. Jackson F.

    Love it, just ordered a glock barrel!

  36. Shelby D.

    Neo chrome barrel looks absolutely stunning and the level of communication from the company was out standing. Item was received within 5 days and the company reached out for every step from the day payment was received to the day it shipped.

  37. Wilson D.

    Very quick delivery!!

  38. Edward Mayo

    Besides being absolutely beautifully made and crafted, they make my Glock43 sooo accurate. 8 inches at 33 yes! Love it!

  39. Blake M.

    I’ve put over 300 rounds through this barrel and the finish is holding up great and it is a overall very nice product.

  40. rickey k.

    quick and easy drop in. couldn’t be happier!

  41. Johnny R.

    So far the barrel is pretty damn accurate. Did not take much break-in and now at about 600 rounds thru it the barrel is still spitting lead down range..

  42. Duncan J.

    Worth every penny and the attention to detail shown in the product is priceless

  43. John H.

    The barrel fits great and looks awesome too. It arrived at my door very soon after ordering and was packaged very nicely.

  44. Michael M.

    The best and only upgrade I have on my Shield. I originally purchased my shield in .40 cal, but after taking to a local gunsmith to mill my slide, who didn’t deliver but also ended up losing all my slide parts including my trijicon HD sights and and Apex trigger kit, I was pretty much done with this gun. Fast forward 2 years later. I found a 9mm complete shield slide on sale for $100 w/o the barrel. So I figured I’d get the black list thread barrel and I must say it’s accurate. It’s straight point and shoot with this. I wish I would have started her with the modifying this guns. I don’t feel the need to add or do anything else on this gun other than night sights.

  45. Carl R.

    Excellent, you guys do things right and stand behind your products. I also like the cool notifications on the shipping and orders. You rock! I’ve order two barrels from you and they are great.

  46. Oscar A.

    Great company. Plan on buying more items in the future.

  47. danny a.

    I love my blacklist barrel // I feel as if it made me a better shooter

  48. Oscar J.

    This is my second barrel from Blacklist. I got an MP9 and a MP Shield barrel. I love these barrels so much I touch myself! True story.

  49. Seng X.

    Great product looks good on the pistol…couldn’t ask for more but a lower price mark on the barrel could be better…thanks…

  50. Jamie L.

    You guys make a great product!

  51. Henry T.

    Glad I bought this product. High quality.

  52. Brandon J.

    Got the MP Shield Threaded Chameleon Barrel for My Girlfriends Performance Center Shield. Fit finish is amazing. She is an avid shooter puts training over bling… but absolutely loves the way it looks. Haven’t had a chance to try it out yet. But positive it will perform as stated. Black List shipped earlier than the stated lead time sent awesome updates order confirmations. Top fuckin notch all the way. I was a bit of a “slow is smooth, smooth is fast” fanboy. But the next Glock barrel for me will be a Black List

  53. Frank Baran

    Will be running this barrel in BUG Comps. Fit & finish is outstanding on the TiN standard Gold barrel I received.. Didn’t do a accuracy test outside do to a rainy days but true indoors at 20 yards. Would recommend this BlackList Barrel to anyone. 5 :thumbsup:’s

  54. Florina L.

    Good looking barrel very accurate

  55. Matt R.

    Awesome finish and perfect fit. Would not hesitate to buy from you guys again.

  56. Oscar J.

    Bought a black barrel for my MandP 9. Stock barrel shoots fine, nothing wrong with it but the Blacklist barrel shoots better. Better grouping, better distance and the fluting just makes it sexy. I was patiently waiting for the Shields to come back and pre-ordered one of those barrels the first notice I got. They sell out fast get yours while you can!

  57. Cody P.

    Do you wanna get ass Do you wanna shoot tight groups Do you wanna run supressed and do hood rat ass shit with your homies Do you wanna show that pawn shop tweaked why yo gats better than a hi point Do you believe in America and the principles we stand for Then this barrel is for you!!! If you answered no to those questions I’ll assume you don’t know which bathroom to use due to your misidentified gender and you hate bald fucking eagles and love watching puppies me beaten with kittens!

  58. Aaron

    These barrels are top notch! I’ve been running mine for almost two years and it’s still eating and spitting out ammo like the day I dropped it in. I’ve probably put about 4K rounds through it and it’s still a champ.
