New barrel manufacturer sets goal of #MakingBarrelsGreatAgain.

October 2nd, 2017: Rosco Manufacturing; a proud American manufacturer of high quality gun barrels is proud to announce the launch of their new Bloodline series AR platform barrels and their new website.

Rosco Manufacturing, from Central Falls, RI, is a barrel manufacturer that produces OEM barrels for some of the biggest gun makers within the industry. Rosco has recently focused their talents and years of expertise to produce commercially available barrels that will rival what is currently found in the market.

Bloodline Series:

Rosco Manufacturing’s “Bloodline” series is our hardest working barrel. Whether you are an occasional builder, tactical shooter, or Law Enforcement Officer we have a barrel that will fit your needs. All of our Bloodline barrels are made from scratch in our Rhode Island facility and start life as a blank piece of steel.

All barrels feature a 4150 CMV steel blank which is then rifled using our proprietary “Rifling & Polishing method” which produce a lapped smooth surface before final Salt Bath Nitride treatment is applied. All barrels are also Air Gauged (Chamber, Bore & Groove) and checked for other multiple points of failure in our in-house QC department before they are shipped out to the consumer.

Aside from making our own barrel blanks, and barrel extensions, we also hold ourselves to the most stringent quality and performance 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 most austere of conditions. We are setting out to re-define the rules and we plan on letting our work do the talking. Barrel calibers offered will be 5.56, .300 BLK, and 9mm with more calibers/ sizes to come.

“We have been observing the commercial market for some time now and found very few companies that were creating products worthy of a customer’s confidence or hard-earned money.”, “This is something that we felt needed to be addressed and we have started to with our Bloodline series of barrels.” — Gabriel Cabrera Marketing & Sales Director for Rosco Manufacturing.
