Details
Details
The AR-15 is by far the most dominant carbine on the market. To stand out, simply building 'good enough' components doesn't cut it. The Bloodline series of barrels was designed and built entirely in-house by Rosco Manufacturing with the sole purpose of providing you with a barrel that will not only outperform the competition but outlast it too.
Features:
- 14.5" Government contour
- Mid-length gas system
- 1/2x28 threading with 11-degree crown
- 1:7 twist flexible round selection
- 41V50 Chrome Moly Vanadium steel
- Corrosion resistant salt bath nitride finish
- Slick nitride-finished M4 barrel extension
- Compatible with standard .750" gas blocks
- 5.56 NATO chamber
Rosco Manufacturing takes their barrels seriously. Rather than entrust someone else's blanks or machining, they produce every barrel from scratch, controlling every step of the manufacturing process. The Bloodline series is cut from high-strength 41V50 Chrome Moly Vanadium steel, the same stuff chosen for the rifles used by our military for its exceptional durability. Improving on the military-grade barrels, the Bloodline-series are finished with a highly corrosion resistant, low friction salt bath nitride treatment, making cleaning easier than ever. By producing these barrels entirely in house, they've also been able to tune each barrel by selecting the optimal twist rates, gas port diameters, dwell times, and materials according to the needs of each barrel.
This 14.5" barrel is machined to a balanced Government contour, offering a solid balance between rigidity and weight. The smooth shooting mid-length gas system ensures your rifle gets the optimal amount of gas for reliable cycling while offering smoother recoil characteristics. The 5.56 NATO chamber is fully compatible with .223 Remington ammunition, with a 1:7 twist rate that is perfect for heavier, precision-oriented cartridges, but is thoroughly functional with popular and less expensive bullet weights.
Rosco Manufacturing got their start producing high quality, hard-use precision rifle barrels. They have since expanded, offering their own line of serious use parts and accessories so you can assemble a rifle that doesn't just shoot good and look good, but will handle hard use as well. To top it off, they're production facility is in Central Falls, Rhode Island so you know that every component is 100% made in America, by Americans.

Roscoe 14.5
by mzlblst -
Wow! Very nice barrel. Only complaint is there is a thin spot in the nitride on underside. But after shooting it did not bother me anymore. First 3 shots from this new barrel went into 3/4" @100 yd. w/Hornady 75gr Interlocks. Next, green tip went into an inch. Next, Hornady frontier 62 gr soft points went into less than an inch. Pinned/welded YHM low profile flash hider, fits barrel profile and finish perfect. And, it works well.
The combo is outstanding. So impressed I put the Roscoe sticker on my truck...
It's a shooter

Only reason why I didn't give this barrel 5 stars is that there were some imperfections on the surface finish just in-front of the gas block. Not a big deal as it is completely covered by my handguard. Only been out to the range once so far, but shooting with iron sights it hits where I'm aiming. From a bench, I was able to hold a 2" group at 50yards which is likely my limit with iron sights (recreational shooter). Very impressed with the handling of the shorter barrel and accuracy. Wouldn't hesitate to buy this again.
