Rosco Manufacturing’s “Purebred” series is a testament to precision and quality manufacturing. We took a step back to see how we could create a barrel line that would be a culmination of all the lessons learned through years of making barrels for several OEM’s. The result is a barrel that will produce results out of the box for any shooter that is looking to take their skills above and beyond. All of our Purebred barrels are made from scratch in our Rhode Island facility and start life as a blank piece of 416R stainless steel.

Aside from making our own barrel blanks, and barrel extensions, we also hold ourselves to the most stringent quality standards. This is the only way that we can make sure that we are producing a product that will perform time after time under the demanding of situations. We are setting out to re-define the rules and we plan on letting our work do the talking…

    So far, so great. Had my mind set on an FN Barrel but decided to give this company my business and delivering MOA with 62 grain MK318? Was a good choice. I like the American company push and the Barrel Gang. Good stuff guys. Keep it up!

  2. dcasteel (verified owner)

    Great barrel and great accuracy. The packaging alone is outstanding.

  3. Jerome Smith (verified owner)

    This barrel is perfect for my build. It is extremely accurate with 62 grain sp and 69 grain match bthp. I would recommend to anyone doing a AR build, who wants accuracy and consistency!

  4. Matthew (verified owner)

    Love my Rosco Purebred 13.7 so much that I bought a second one. Was amazed at how good the accuracy was from this barrel given the length. Great aesthetics, great packaging and great all round barrel.

  5. Marcus (verified owner)

    I am giving it 5 stars based on the quality of manufacturing and the attention to detail in the creation of the barrel. I have not had a chance to take it to the range because my build is not complete. I am so pleased to have found a company offering a 13.7″ barrel with the mid-length gas system, kudos to Rosco Manufacturing. I have heard nothing but great things about your products.

  6. Marcus (verified owner)

    I have heard nothing but great things about Rosco manufacturing and their barrels. I have to give it 5 stars based on the quality and attention to detail of the barrel, will give an update once the build is finished and I have taken it to the range.

    I have been building rifles in the AR platform for over 20 years and have seen the good, the bad and the ugly. The 13.7 Purebred Barrel for Rosco is on the best end of Good. In fact the machine work and finish on the barrel I received is almost to the “work of art” level, its absolutely perfect. I bought this with a Rosco adjustable gas block and BCG, the quality of these components is perfect as well and because they all came from the same manufacturer they fit together with no problems. I am making Rosco my go-to company for builds from now on. Thanks Barrel Gang!

    I have been shooting precision rifles for many years and have recently transitioned into building/ shooting shorter barreled carbines. My needs have evolved to include a smaller lighter carbine for 3-Gun and RECCE style matches.

    I never expected this barrel to perform as good as it has. I have personally been able to lay down 1/2” groups at 100 yards using 55gr Atlanta Arms ammo. I have only ever experienced this out of my bolt action guns or longer barreled DMR carbine builds. I can easily rate this barrel 10/10 and highly recommend it for those that want a perfectly balance “Jack of all trades” rifle.

    I purchased this barrel after a toss up with Triarc (who makes a 13.9). My initial thought was “lower price, lower quality”.
    I was wrong.
    The barrel itself looks well manufactured. Visually, you can see the QC was on point. But barrels are covered by hand rails, so who really cares, right?
    After I assembled the gun, I sent it off for testing with my local SWAT guys, a couple special military friends, and a federal agency shooter.
    The barrel performed beyond standard. It stabilized everything we fed it (50gr to 77gr, cheap a** steel to SMK). T performed so well, that a couple of my friends are now working to get a Rosco for their next build.
    I just informed them the 13.7 must have gotten popular because it’s on back order lol. You should see the faces lol.
    The barrel is well gassed and functions perfectly. I don’t what kind of virgin sacrifices you guys pulled, but the gas system itself runs comfortably with various buffer set ups. From SCS, to flat wires. I like have that option just in case.
    I have e yet to have a key hole even with it being 1-8, it does its job well.
    I will most definitely be returning for another barrel, for another build in the future.

    I’ve had my 13.7″ for nearly 6 months, 3300 rounds through it of various weights and manufacturers. It runs them all well and the accuracy is dead accurate. The barrel compliments the overall rifle with it’s perfect length after being pinned and welded. With the Rosco gas block/tube added, it is gased right and runs flawlessly. Minimal recoil impulse and muzzle rise with the right bugger weight/spring combo. It truly makes my rifle a joy to shoot. Keep up the good work Rosco Manufacturing!

  11. Eli Hughes (verified owner)

    This is by far the best barrel I’ve ever owned. And I’ve owned some higher end barrels, nothing beats this quality and finish. 100% recommend for anyone who wants a durable, accurate barrel you can shoot countless rounds out of. Will definitely be buying more of their products.

  12. Tim

    I bought one of these from Primary Arms a few months ago. It is the second Rosco barrel I’ve bought, but first Purebred. Fit and finish is fantastic and it shoots really well. My build has been 100% reliable with a standard carbine buffer across a broad range of ammo. Mine seems to fall short on accuracy. I’ve had a few sub MOA groups with it, so it is capable, but it seems to be closer to a 1.5″ barrel with match ammo and a 2″ barrel across the 14 different rounds I tested. I’d be stoked if this were the Bloodline barrel, but I can’t help but be a little disappointed. However, I do which rounds it should be sub MOA with now and intend to test those again!

  13. Steve W (verified owner)

    Shipping took a tad longer than anticipated due to the holidays but well worth the wait! Really not kidding about the QC on these barrels. Finish is impeccable! The barrel extension was insanely tight going into the upper receiver. Not a complaint by any means. With a dead air brake on the end and a fortis night rail over the barrel, it makes for one sexy looking cqc tool. Have not had a chance to test fire yet, but I’m sure it will be epic. Btw, love that you guys dimple for the gas block. Ill be doing business with you guys again, for damn sure.

  14. Andrew (verified owner)

    I haven’t shit tested the barrel yet but only because it was so much nicer than i expected. I didn’t want to mount it on the budget build i had planned and instead ordered a cmt upper and lower just for this barrel. Awesome work Roscoe, Im glad i found you just because i needed a 13.7. Once the DeadAir Break comes back in stock i will be ordering that as well. I will deff recommend more people check you out.

  15. Matt C (verified owner)

    Haven’t installed it yet as I’m waiting for a few gas block parts and muzzle device but this thing is sweet! Shipping was pretty quick and well packed. I’m looking forward to finishing my build and bustin some caps through it.

  16. Erick

    The 13.7 is my third barrel from Rosco. What can I say. It’s an AWESOME barrel, especially for the money. If you’re on the fence, just buy it you won’t be disappointed.

    Best barrel purchase I’ve made! The machining, finish and QC on the barrel is top notch. The 13.7 is paired with Rosco non-adjustable gas block/tube as well as a Bootleg Inc Adjustable BCG. Recoil and muzzle rise are minimal both suppressed and unsuppressed, and accuracy with different weights of 223 | 5.56 is spot on. This is my go to config now and it still fits folded in the Haley Incog SMG bag like my 10.5

    Don Edwards from the barrel gang turned my on to Rosco at a carbine class a couple years ago, I then met Gabe and his professionalism and knowledge sealed the deal. This 13.7″ is my third Rosco barrel 10.5 -11.5 – 13.7 and as someone who trains quite a bit, I am extremely happy. The accuracy is beyond my expectations, the build quality is absolutely as good as ANY barrel I have owned…Odin -FN – BA – Faxon and is some ways better. I try not to mention the low cost because this usually turns people off, but understanding that they are the actual full manufacturer of this product reflects in the amazing price of this top shelf product. I am now a loyal customer and all of my barrel replacements and future builds will have a Rosco in them, and it’s not because of the price…it’s the performance period.

  19. Tom Cardarelli (verified owner)

    Very pleased. Excellent accuracy for a barrel in this price range. Rosco is doing something right with this barrel.

  20. Brian Clarke (verified owner)

    I haven’t tried Rosco Barrels. But I heard good things about then. I wanted a 13.7 barrel and this company had the highest quality with the lowest price. It’s a amazing deal. I haven’t build the ar just yet but I know I will be amazed.

  21. Wesley Pipes (verified owner)

    Haven’t been able to shoot it yet due to the Rona but machining is solid. I’ll update when I get to shoot it.

  22. icebawkz (verified owner)

    Such a nice piece! Fit and finish are second to none. I will definitely be adding another Purebred barrel to my next build! Bravo Rosco!

  23. ThePewLifeChoseMe

    Outstanding accuracy. Always sub MOA with 69gr SMKs, generally closer to 1/2 MOA. Haven’t shot past 200 yds, but sub MOA results are consistent 👌🏻

  24. Stephen Passariello (verified owner)

    This barrel kicks ass. It’s just that simple.

  25. Edward Lamb (verified owner)

    Absolutely beautiful barrel. Finishing up my build shortly and hoping to run some rounds through it soon. Even during the Covid-19 pandemic it was at my door in 3 days.

  26. Brandon Olson (verified owner)

    First off let me say that the barrel packaging alone is worth it!
    In all seriousness, this barrel is crazy good.. I’m getting better accuracy with this 13.7 than I do some of my 18-20 inch rifles! Excellent little package with quality to boot. I recommend getting a dead air flash hider pinned and welded so you can have the mobility of a SBR/pistol with the legality and convenience of a 16 inch rifle. This is on my new truck gun, and I’m trusting my life with it. I suggest you do the same

  27. Michael Belch (verified owner)

    13.7 in barrel. I have build several ar15s with various types of barrels anything from stoner to Rainier even to a couple more expensive. but the performance of this barrel so far has been much better. more accurate and easy to break in and clean. Very impressive. My next builds will be done with rosco barrrls
