Rosco Manufacturing Purebred 10.5" 300 BLK Heavy 1:7 Twist Pistol Stainless BarrelPurebred 10.5" 300 Blackout Barrel: This Rosco Purebred 10.5" 300 Blackout Barrel was designed for SBR/ Pistol use in conjunction with suppressors. The 10.5" Rosco barrel was made to be a direct precision replacement for any MK 18 platforms that are currently in 5.56 NATO. The 10.5" barrel is also perfect for carbines that require a slightly longer rail in order to run PEQ-15's, D-BAL (series), or any laser aiming devices comfortably. ALL NFA RULES APPLY!Rosco Manufacturing's "Purebred" series is a testament to precision and quality manufacturing. We took a step back to see how we could create a barrel line that would be the culmination of all the lessons learned over the years of making barrels for several OEMs. The result is a barrel that delivers out-of-the-box performance for any shooter looking to take their skills to the next level. All of our Purebred barrels are made from scratch in our Rhode Island facility and start life as a blank piece of 416R stainless steel.In addition to making our own barrel blanks and barrel extensions, we hold ourselves to the most stringent quality standards. This is the only way we can ensure we produce a product that will perform time after time in demanding situations. We are setting out to redefine the rules, and we plan on letting our work do the talkingSpecifications Barrel Length: 10.5" Barrel Weight: 21.09 oz Barrel Material: 416 R Barrel Caliber: 300 BLK Barrel Profile: Heavy Twist: 1:7 Barrel Thread: 5/8 x 24 Barrel Gas Block Size: 0.750 Gas System Length: Pistol Barrel Crown: Step Crown Barrel Finish: 80 Grit Bead Blast Barrel Extension Finish: Nickel Boron
