Most Helpful Positive Review Rosco 13.9 mid length
This barrel is a Rosco 13.9 barrel that is mid length gas system. And the barrel is dimpled for a gas block (don’t know who answered my question above, but they’re wrong). Haven’t shot it yet so can say how good the accuracy is, but it’s exactly what I was looking for (13.9 barrel that’s mid length that doesn’t break the bank)

So far so good

by Reclusive, Verified Owner from NC, United States Written on April 14, 2024
Only a few hundred rounds but everyone that said rosco makes great barrels is not wrong. Threads are clean, finish looks amazing and the barrel is indeed dimpled on mine for the gas block. I dont expect to wear this one out any time soon with how little I shoot but expect to purchase more for other builds

Great barrel

by Ty, from CO, United States Written on February 4, 2024
Haven't put it on an upper yet, but finish looks awesome and if it's like my other rosco barrels it will shoot great.

Great barrel, but even better price

by RCD, Verified Owner from GA, United States Written on August 16, 2023
This is a well machined barrel. I was very surprised given the price. I had not owned a Rosco barrel before making this purchase, but I would definitely again. The machining is excellent, as well as the finish. Perfect fit into the upper. Can't say enough, very satisfied.
Pros:
  • Price
  • Fit
  • Finish
Cons:
  • None
Best Used for:
  • Range
  • Small game hunting

underrated

by Jason Edwards, Verified Owner from SC, United States Written on May 18, 2023
This is my second barrel from OP. The first one has over 1000 rounds. And is paired with a BCM upper and standard BCM gas block. H buffer. NOX9 pin n weld. And it shoots very smooth and flat. 1.5 MOA with 55gr Winchester white box. Group tightens up a little with the heavier grain stuff. And would most likely be a Moa barrel with someone better than me. For the price. I haven’t found anything better. Not an over gased barrel unsuppressed. Probably want an adjustable gas block for suppressed use. I had to buy a second one as a spare because I was so impressed with it. Shipped quick. Packaged well. Looks great. For $130 when I got it. We’ll work it. For what it’s worth. I do lap my upper receivers. And torque everything to spec.

great for price

by Jason Edwards, Verified Owner from SC, United States Written on February 18, 2023
Bought through OpticsPlanet. Showed up on time packed well. Barrel was dimpled for gas block. Used a NOX9 pin & weld. Only have about 500 rounds through it so far. Seems to be a good barrel so far. Feed ramps looked good. Mine shoots very flat with standard BCM gas block and H2 buffer. This one is a little gassy. But not near as bad as a couple others I have. May want to use an adjustable gas block for suppression. Very good looking barrel. Great length for a pin n weld. Will be buying another one of these, or the ballistics advantage. Just depending on what’s available when that time comes.

Solid Barrel for a Decent Price

by Marcus, Verified Owner from MO, United States Written on July 27, 2022
Good barrel, feed ramps line up good. The length is great for pin and weld. The crown is well done and the finish overall is fantastic. Accuracy is pretty good, I haven’t shot for serious groups but it is about 2 MOA with cheap PMC bronze. My only issue is the gas port is huge, if you don’t get an adjustable gas block you get a lot of gas in the face.
Pros:
  • Length, price, accuracy.
Cons:
  • Gas port to big
Best Used for:
  • Fighting rifle.
Would recommend: Yes
