    Excellent craftsmanship. Have not been to the range yet but I expect it will perform as good as it looks.

    I just obtained my Rosco barrel, prompt & quick delivery I might add. I immediately hit the range and was instantly taken in by the accuracy! My groupings before were good, with this barrel they are great! My average score on my RI CCL test is a 275. Twice with the Rosco barrel I scored a 297 & a 294. All my guns That are not already Rosco barrels are making the swap! Can’t wait to see what else Rosco has in store!!!!!!!

    Anybody know if they will have any threaded barrels for the glock 9mm coming up anytime soon if I knew a date I might hold out and get one but sure getting ready to buy a barrel soon

    Fit and finish is great. Hoping you guys make barrels for different make and models in the future.

  5. Reece Riegel

    The fit is great! I feel like it fits better than an OEM just the way it goes into the slide. Finish is perfect. Havent been out to the range with it yet, but have a few ar barrels and I’m sure this one will shoot just as good.

    No change in reliability, looks good, shoots good, if you need a new barrel, get it

    I love Rosco barrels!! this is my second non-threaded G19 barrel. quality control is awesome and flawless. just by looking at the finish product and the box it came in, everyone at rosco manufacturing made a really awesome piece. so far this is my 5th barrel from rosco, ive got 2-7.5″, 2-g19 9mm(non-threaded)and a 14.5″ 223 wyld. Ive been on the wait list for the threaded version for quite some time now. for the price , cant go wrong….awesome finish, accurate and reliable, not to mention quick shipping too!! im a big fan and going to be one for a long time!

    I have purchased Bloodline Barrels before, and have never been disappointed. (2) 14.5″, (2) 12.5″, and (1) 11.5″, all in 5.56. Each barrel has 1,000 rounds through them. Still perform excellent. So I immediately jumped on the G19 barrel for my poly 80 build in 9mm. I dropped it in the slide right out of the box. I shot 15 rounds slow fire from the 25 yard line, 5 failure drills at the 15, and 6 hammer pairs from the 10. the only issue I had, was with a new magazine (Magpul Glock 19 mags) feeding once. All rounds grouped inside a 7″ kill circle. super happy

    Excellent quality and craftsmanship. I expected nothing less.

    Received my G19 barrel (non-threaded…quit laughing I’m from CA so can’t run a suppressor anyway) today; opted for free standard shipping (I’m not in a rush) and received seven days after my order, which is pretty quick in my book. While I haven’t shot it yet, the workmanship is immaculate and was extremely impressed with the packaging; fitted foam lined Rosco-branded box, inside a white outer box inside a brown shipping box secured with twine-reinforced packing tape on top and eight copper staples on the bottom. I’ve had sticky-fingered postal workers open other firearm-related purchases in the past so seeing this level of security was impressive.

    Most folks would think the price is on the expensive side, you get what you pay for…now just waiting for the G17 barrel.

    Excellent quality and product. Great proce and really fast shipping.

    This is the 2nd G19 barrel I have purchased from Roscoe. It arrived today, & I immediately went to the range. Once there, I took the barrel out of the box, installed it on my build, & began to warm it up by doing hammer pairs out the holster with 50 rounds at 15 yds. No lube, spit, or anything. The results speak for themselves. Wish I could insert the pics. Just one big hole in the center of the target. If you do not have one already, you are lacking.

    Works perfectly in a Glock 19 Gen 2. Bought it to replace the OEM Glock barrel that Bubba had destroyed attempting to polish the feed ramp. 200 rounds with zero malfunctions. And I like that this barrel is designed to reduce wear and tear, especially on an older Glock 19 Gen 2. Highly satisfied.

  14. Michael (verified owner)

    Amazing quality and accuracy for my Gen 3 G19. More accurate than the OEM barrel and runs amazing. I have done 3-weekend tactical classes with this barrel and the accuracy is soooo good. I am beyond happy and always recommend it to others.
