Stainless Steel AR Barrels

Stainless Steel AR Barrels | Precision Machined & Fluted Options | Boss Barrels

When performance and durability are non-negotiable, Boss Barrels stainless steel AR barrels deliver. Machined entirely in-house in Lufkin, Texas on industry leading CNC equipment, every stainless barrel we produce is held to the same uncompromising standard that has made Boss Barrels one of the most trusted names in precision barrel manufacturing.

Every barrel starts from a fully stress relieved, air gauged 416R stainless steel blank — button rifled, chamber cut to exact specifications, and inspected before it ever leaves our shop. The result is a barrel that offers exceptional corrosion resistance, consistent accuracy, and long-term durability in any condition — from the range to the field.

For shooters looking to reduce weight without stepping up to a carbon fiber wrapped barrel, our fluted stainless steel barrels are the answer. Strategic fluting removes material from the barrel profile — reducing overall weight, increasing surface area for faster heat dissipation, and giving your build a distinct, aggressive look without compromising structural integrity or accuracy.

Every Boss Barrel stainless steel barrel is sub-MOA guaranteed and available in a wide range of calibers, lengths, twist rates, and gas system configurations to fit any AR-15 or AR-10 build.

No outsourcing. No shortcuts. Boss built.
